Important: Xerces has added a number of DOM level-3 methods to its DOM interfaces. The DOM level-3 proposal is currently a working draft (it is not yet a W3C recommendation), and Xalan does not support these new methods. To run Xalan in the JDK 1.1.8 platform, you must put xalan.jar (with its DOM level-2 interfaces) in front of xerces.jar on the system class path. If you want to rebuild Xalan (on JDK 1.1.8 or higher), you must put Xalan in front of xerces.jar on the system class path.

This beta release includes the following changes:

• Costin Manolache has slightly modified the CoRoutine stuff so that a you can compile and run everything but the CoRoutineXercesParser without having Xerces on the classpath.
  
  
• Joseph Kesselman added chunked int array stuff to address our scaling problems that Mukund & co. uncovered. This was a fairly mechanical, but still substantial, change. No bugs have yet been discovered that relate to this. This is probably the most controversial change.
  
  
• The Process class now outputs incrementally if the output is standard out. This is mostly for testing purposes, but it makes general sense.
  
  
• Bug was fixed with setting the incremental flag in TransformerFactoryImpl. Clearly the change was made but never tested. Simply a missing 'else'.
  
  
• Fix for Bugzilla Bug 2275, Xalan did not fire the right templates. This was substantial and somewhat risky. Xalan had several problems related to the last() function. Fixes cover four axes files.
  
  
• Change PrintTraceListener to output the file, as well as the line numbers. This is really a feature change, but simple, and aids diagnosing problems with multi-part stylesheets.
  
  
• XPath fix: the XPath API wasn't working correctly due to a problem with with NodeSet/NodeIterator adapters. This fix ended up interacting quite a bit with the #2275 fix.
  
  
• Fix for the Norm Walsh bug posted 06/20/2001: iterators weren't always being cloned correctly from the variable value stack. This fix is not without some risk, though we haven't seen any problems since Scott Boag made it.
  
  
• David Bertoni added missing html element properties to SerializerToHTML.java.
  
  
• Shance Curcuru modified TransformerFactoryImpl.setAttribute() to accept a String ("true" or "false") as well as a Boolean object to set the value of a Boolean attribute.
  
  
• TransformerHandlerImpl was threading when incrementality is turned off. Scott Boag has fixed this bug.

• Handling xsl:namespace-alias declarations: In release 2.0.D01, we reported the need to do some research concerning exactly how Xalan should handle xsl:namespace-alias declarations. As a result of discussions among members of the W3C Working Group on XSL, we have reached a more precise consensus on how namespaces should be represented when an xsl:namespace-alias declaration is in effect.
  
  If a literal result element has a namespace prefix, the prefix will be preserved and the namespace URI of the element will be as specified in the xsl:namespace-alias element, but the result-prefix is not required to appear in the result. This also applies to the two other cases of "Literal namespace URI" mentioned in the XSLT Recommendation on Literal Result Elements. More simply, if the stylesheet calls for <axsl:foo> to be output as a literal result element, then it will be output as <axsl:foo> in the result, but the namespace associated with this "axsl" prefix will be as designated in the xsl:namespace-alias declaration.
  
  
• For HTML output, Xalan-Java 2 outputs character entity references (&copy; etc.) for the special characters designated in Appendix A. DTDs of the XHTML 1.0: The Extensible HyperText Markup Language. Xalan-Java 1.x, on the other hand, outputs literal characters for some of these special characters.
  
  
• In conformance with the XSLT Recommendation on the HTML Output Method and Section B.2.1 of the HTML 4.0 Recommendation, Xalan-Java 2 uses %hh encoding for each byte of the UTF-8 representation of non-ASCII characters in HTML URI attributes.
  
  
• When your stylesheet asks for an explicit carriage-return character (&#13;) to be inserted into the output, it is output during the serialization process in escaped form unless escaping has been disabled. When your stylesheet asks for an explicit line-feed character (&#10;) to be output, the system-default line-break character(s) is/are output during the serialization process. Also keep in mind that the XML parser normalizes line-breaks to line-feeds when it sends character events to the processor.
  
  
• If your XML input is a DOM, use the javax.xml.parsers.DocumentBuilderFactory setCoalescing() method to set coalescing to true (it is false by default), if you want to append CDATA sections to adjacent text sections to form a single text node (as the XPath standard calls for), and if the XML parser supports this feature (Xerces-Java version 1.4.1 does not).

All known Xalan-Java bugs are listed in Bugzilla (the Apache bug database). For a list of open bugs with links to each bug report, see XalanJ2 open bugs. If you find a new bug, please enter a XalanJ2 bug report in this database.

Before you can enter your first bug report, you must submit your email address to Bugzilla and receive a password.

We strongly encourage you write patches for problems you find and submit them to xalan-dev@xml.apache.org. We review the patches we receive to make sure they do not break something else, and (assuming they do not) include them in our next release. In the interest of fixing bugs, adding enhancements, and addressing outstanding design issues, we sincerely want (and need!) your active participation in the ongoing development of Xalan.

Xerces bug in Xerces-Java version 1.4.1:

• Xerces-Java version 1.4.1 does not process namespaces in SAX events when parsing UTF-16 documents, which causes Xalan-Java to fail with UTF-16 documents. Xerces will post a fix shortly.
  
  

The Xalan-Java version 2.2.D6 has been tested with Xerces-Java version 1.4.1. The Xalan-Java version 2.2.D6 download from xml.apache.org includes xerces.jar from Xerces-Java version 1.4.1. For information about including xerces.jar on the system class path, see Setting up the system class path.

Important You may experience unpredictable anomalies if your Xalan and Xerces builds are not in synch. If you download an update to Xalan, check the release notes to determine which version of Xerces you should use.

You can use Xalan with other XML parsers that implement the Java API for XML Parsing 1.0. See Plugging in the Transformer and XML parser.

For a list of goals, tasks, and target dates for completion, see Xalan-Java Version 2: Things To Do. As tasks are completed, they are moved from the to-do list to Completed.

The source document for the to-do list is an active document in the Apache CVS repository: xml-xalan/java/todo.xml.

  Committer's log entry: Added a fix for local variables inside nested xsl:for-each elements. Local variables are usually not initialized to any default value (such as with general Java classes), because code compiled for <xsl:variable> elements always assign values to variable slots before they are accessed. But the code structure generated by nested <xsl:for-each> elements is too much for the JVMs verifier to get around, so we have to initialize all local variables inside such loops to zero, false, null, whatever. This takes care some of our runtime-errors caused by apparent corrupt code. (The JVMs verifier thinks that it is corrupt, but it isn't really.)

XSLTC does not yet support the following features of the :

• The namespace axis is not implemented. You cannot get a node set containing the namespace nodes in scope from a context node in the document tree. Otherwise, namespace functionality is implemented.

XSLTC does not support a number of features that are not required by the XSLT 1.0 specification, but which are supported by a number of other XSLT processors:

• Incomplete support for extension elements and external Java functions. Currently you can set up an extension function to call a static Java function. For the extension namespace, use
      http://xml.apache.org/xalan/xsltc/java/<class>
  where <class> identifies the class with the static method.
• Lack of support for the redirection of output to multiple output files from within a stylesheet (equivalent to xalan:redirect or saxon:output).
• XSLTC does not implement a node-set extension to convert result tree fragments to node-sets. This would enable sorting and grouping of nodes assigned to a tree

• Casting variables: XSLTC requires you to explicitly type cast values returned by variables or expressions, when you use them in tests. Always a good practice, but it may seem like overkill in some in contexts, where other XSLT processors automatically assume or convert to the correct type. For example. unless you cast $country to a string in the following apply-templates, entry nodes whose <country> elements contain a string matching the global $country parameter are NOT selected.
  
      <xsl:apply-templates select="entry[country=string($country)]"/>
• Order dependency of conditions within a predicate: If you have a predicate in a select or match expression that has multiple conditions, one of which contains a union (X or Y), put it last. Otherwise, the predicate fails to match node that it should.
• When using DOM caching, as shown in the Servlet demo, if the source document is local to the server, the cache is not refreshed when the source XML document is modified. This problem does not apply when the source is associated with a URL.
• If you have a list of references included or imported stylesheets, put any with a relative path last; otherwise, stylesheets in the current directory are not found.
• [1] should be treated equivalent to position()=1, but it is not. Therefore, if you get unexpected results using such shortcut positional predicates, substitute the full postion()= version.
• XSLTC fails to match existing nodes when match expressions have multiple steps with predicates containing the position function. The following examples are taken from the XSLTMark oddtemplates.xsl test:
  
      match='top/*[position()=2]'
    match='top/*[6]/kid[2]'
    match='top/*[position()=last()]'
  
• XSTLC has problems with output escaping, see bug 1403.
• Case-order option with sorting is ignored.
• As a minor side-effect of implementing simplified stylesheets, if you inadvertenly go to compile a stylesheet and give the name of the .xml doc instead of the .xsl doc, it may compile without a warning. In some cases, the compiler aborts with an error about too many branches.

XSLTC provides demos for using XSLTC as a servlet and as a handler for Brazil (a new and powerful Web techology from Sun labs). To run these demos, download Brazil from sunlabs:

    http://research.sun.com/research/download/index.html

and the java extensions for servlets from Sun:

     http://java.sun.com/products/servlet/download.html

The translet must be specified as a pure class name, accessible through the Brazil handler's classpath. For example:

    translet=mk054

The document must be specified as a valid URL. For example:

    document=http://server/path/to/filename.xml

If the file is local to the Brazil handler, it has to be specified using the "file:filename.xml" format.

You also need to make the Brazil and javax classes available from your classpath

See also: sample JAXP translets.

The Translet API has been extended to conform with the JAXP1.1 TrAX model. This release contains the first implementation of that extension. Two new classes have been added to the Translet XSLT codebase, they are:

(1) org.apache.xalan.xsltc.runtime.TransformerFactoryImpl -
    the Translet implementation of a SAXTransformerFactory.

(2) org.apache.xalan.xsltc.runtime.TransletTemplates -     the Translet implementation of a Templates object.

The existing XSLT class 'org.apache.xalan.xsltc.runtime.AbstractTranslet' that implements the Translet interface is now also extending the javax.xml.transform.Transformer abstract class.

This implementation is only a partial implementation, with many limitations. These limitations include:

1. Currently 'StreamSource' and 'StreamResult' are the only TrAX Sources and Results that are supported.
2. The translet is compiled everytime a call is made to the
   TransformerFactoryImpl 'newTransformer()' method.
3. The translet is compiled everytime a call is made to the
   TemplateFactoryImpl 'newTransformer()' method.
4. Translet are currently not cached. (See (2) and (3)).
5. Several abstract methods from SAXTransformerFactory still need to be implemented in the xsltc.runtime.TransformerFactoryImpl class:
   
       TemplatesHandler newTemplatesHandler()
    TransformerHandler newTransformerHandler()
    TransformerHandler newTransformerHandler(Source src)
    TransformerHandler newTransformerHandler(Templates templates)
    XMLFilter newXMLFilter(Source src)
    XMLFilter newXMLFilter(Templates templates)
6. Several abstract methods from Transformer still need to be implemented in the AbstractTranslet class:
   
       ErrorListener getErrorListener()
    void setErrorListener(ErrorListener)
    Properties getOutputProperties()
    String getOutputProperty(String name)
    void setOutputProperties(Properties props)
    void setOutputProperty(String name, String value)
    URIResolver getURIResolver()
    void setURIResolver(URIResolver resolver)
7. Abstract method from Templates still need to be implemented in the TransletTemplates class:
   
       Properties getOutputProperties()
8. Several abstract methods from TransformerFactory still need to be implemented in the xsltc.runtime.TransformerFactoryImpl class:
   
       ErrorListener getErrorListener()
    void setErrorListener(ErrorListener listener)
    Object getAttribute(String name)
    void setAttribute(String name, Object value)
    boolean getFeature(String name)
    URIResolver getURIResolver()
    void setURIResolver(URIResolver resolver)
    Source getAssociatedStylesheet(Source src, String media, String title,
        String charset)
    Templates newTemplates(Source xslSrc)
    Transformer newTransformer()
9. Whenever possible, the required methods that are currently unimplemented will throw an exception if someone tries to call them- this will alert the user that the method is not implemented. The message is of the form:
   
       "<Class Name>:<Method Name>( <args> ) not implemented yet."

XSLTC Changes for Xalan-Java 2.1.0

The Sun XSLTC team (david.hofert@east.sun.com, tom.amiro@east.sun.com, todd.miller@east.sun.com, morten.jorgensen@Ireland.sun.com) has checked XSLTC into the Xalan source tree, and we have begun the process of merging XSLTC into Xalan. XSLTC provides a compiler for compiling stylesheets into translets, and a streamlined runtime environment for using translets to transform XML input. In the near term, XSLTC will appear in a separate JAR file (xsltc.jar) with its own API and command-line utilities. You can already use the same JAXP interfaces to perform transformations with the Xalan transformer and with translets. Over time, we plan to merge the two codebases. See XSLTC Design Documents.

Since this is the first release of XSLTC on Apache (xml.apache.org), changes are relative to Preview 5 of XSLTC posted on www.sun.com/xml/developers.

• Simplified stylesheets are now implemented.
• Base package name has changed from com.sun.xslt to org.apache.xalan.xsltc
• You no longer have to get the BCEL.jar file; it is included in the distribution.
• The Project X parser components and APIs have all been replaced with JAXP equivalents. Consequently, you may deploy XSLTC with JAXP-conformant parsers, such as Xerces or Crimson.
• Previously undocumented feature: -x. You can use the -x option on the java command line when you compile translets or run them to get more detailed information on errors.
• Addition of -s to DefaultRun - a new -s option has been added to the DefaultRun class for use with test auotmation. When you use the option, it prevents System.exit() from being called when and exception is encountered.

Apache Ant is a flexible, powerful, and easy-to-use Java build tool that we include with the Xalan-Java distribution. The Ant JAR file is in the bin directory, and the cross-platform XML build file (build.xml) is in the root directory along with a Windows32 batch file (build.bat) and a UNIX shell file (build.sh). The build file defines the "targets" that you can use Ant to build. The batch and shell files set up the classpath and launch Ant with the target (and any other arguments) you provide.

Instructions for using Ant

1. Set the JAVA_HOME environment variable to the JDK root directory.
   
   If you are using JDK 1.1.8, you must also put classes.zip in the JDK bin directory on the classpath. You can use Ant with JDK 1.1.8 to compile and jar the Xalan-Java source files, but you must have JDK 1.2.2 or higher to build the documentation.
   
   
2. Depending on your environment, run the batch file (build.bat) or shell file (build.sh) from the Xalan-Java root directory, optionally with arguments (see the table of targets below).
   
   The batch/shell file adds several JAR files to the classpath and launches Ant with any arguments you provide. If you provide no target, Ant compiles the source files and rebuilds xalan.jar (the "jar" target).

You can also set up your classpath manually (see build.bat or build.sh for the details), and then run Ant as follows:

java org.apache.tools.ant.Main target

where target is nothing (for the default target) or one of the following.

If you build a target that depends on other targets, Ant creates those other targets in the correct order.

The Xalan-Java build is in xalan.jar. The Xalan-Java source code tree is in the src directory.

If you are using Ant, the target is jar (the default). For more information, see Using Ant.

If you want to do the build without Ant, keep the following in mind:

• Set the classpath to include the src directory, xerces.jar, bsf.jar, and bsfengines.jar.
• Use a Java compiler (such as the IBM Just-In-Time compiler or the Sun javac) to compile all the .java files in the src tree.
• Use the Sun jar utility to store the resulting .class files in xalan.jar

If you modify a sample and want to recompile it, you can run the Java compiler in the directory containing the example. Be sure xalan.jar and xerces.jar are on the classpath. To recompile (and run!) the class files in the Servlet subdirectory, the javax.servlet and javax.servlet.http packages must also be on the classpath. Sun distributes these packages in the JSWDK 1.0.1 servlet.jar file.

After recompiling a sample, you can use the Sun jar utility to place your new .class files in xalansamples.jar.

You can use Ant with the samples target to recompile the samples and place the unpackaged class files in xalansamples.jar. For more information, see Using Ant.

To rebuild (and to run) the sample servlet, the javax.servlet and javax.servlet.http packages must be on your classpath.

Xalan-Java includes a number of XML source files, XSL stylesheets, document type definition (DTD) files, entity relationship (ENT) files, graphics, and a JavaScript file that provide the input for the Xalan HTML User's Guide, and the overview and package-level documents used during the generation of Javadoc.

To rebuild the documentation, you must use the StyleBook tool and the JDK 1.2.2 java and javadoc tools. StyleBook (which uses Xalan and Xerces) is in stylebook-1.0-b2.jar. Some of the document definition files, stylesheets, and resources are stored in xml-site-style.tar.gz, and are unzipped when you run Ant as described below.

You can use Ant with the docs target to regenerate the User's Guide and with the javadocs target to regenerate the Javadoc API documentation. For more information, see Using Ant.

If you want to rebuild the documentation without using Ant, keep the following in mind:

• Unzip xml-site-style.tar.gz into the xdocs directory (the operation places files in a number of subdirectories).
  
  
• Be sure stylebook-1.0-b2.jar, xalanjdoc.jar, xalan.jar, bsf.jar, bsfengines.jar, and xerces.jar are on the class path.
  
  
• To build doc in a build/docs subdirectory, run StyleBook from the xdocs directory as follows:
  
  java org.apache.stylebook.StyleBook "targetDirectory=../build/docs/" sources/xalanLocal.xml style
  
  
• To build the HTML source files that javadoc needs for the TrAX top-level and package-level documentation, add a build/docs/apdidocs/javax/xml/transform directory and run the Xalan command-line utility from the xdocs directory as follows (all one line):
  
  java org.apache.xalan.xslt.Process -in sources/trax/trax.xml -param package-root '../../../src/' -xsl style/stylesheets/spec.xsl -out build/docs/apidocs/javax/xml/transform/trax.html
  
  
• Before you run javadoc, make sure the following directory structure exists under the Xalan root directory: build/docs/apidocs.
  
  
• To build the API documentation, run the JDK 1.2.2 javadoc tool from the xdocs directory (all one line):
  
  javadoc -doclet xalanjdoc.Standard -docletpath ../bin/xalanjdoc.jar -private -overview ../src/javadocOverview.html -sourcepath ../src -group TrAX "javax.xml.transform*" -group Xalan_Core "org.apache.xalan.processor: org.apache.xalan.templates: org.apache.xalan.transformer" -group XPath "org.apache.xpath*" -group Utilities "org.apache.xml.utils*" -group Xalan_Other "org.apache.xalan.client: org.apache.xalan.dtm: org.apache.xalan.extensions:org.apache.xalan.res: org.apache.xalan.stree:org.apache.xalan.trace: org.apache.xalan.xslt" -group Xalan_Extensions "org.apache.xalan.lib*" -group Serializers "org.apache.xalan.serialize" org.apache.xalan.client org.apache.xalan.dtm org.apache.xalan.extensions org.apache.xalan.lib org.apache.xalan.lib.sql org.apache.xalan.processor org.apache.xalan.res org.apache.xalan.stree org.apache.xalan.templates org.apache.xalan.trace org.apache.xalan.transformer org.apache.xalan.xslt org.apache.xpath org.apache.xpath.axes org.apache.xpath.compiler org.apache.xpath.functions org.apache.xpath.objects org.apache.xpath.operations org.apache.xpath.patterns org.apache.xpath.res org.apache.xalan.serialize javax.xml.transform javax.xml.transform.dom javax.xml.transform.sax javax.xml.transform.stream javax.xml.parsers -d ../build/docs/apidocs -windowtitle "Xalan-Java 2" -doctitle "Xalan-Java 2" -bottom "Copyright © 2000 Apache XML Project.

This release includes the following changes:

• Deprecation of the Xalan-Java 1 compatiblity API
• The DTM
• Other optimization work

The primary focus of the 2.2 Developer releases is incorporation of all our work over the past several months on the Document Table Model (DTM).

As a result of the changes in *internal* api, you may encounter problems with extensions. We have done some bug fixing in support for extensions since 2.2.D1. John Gentilin is working on fixing the SQL library extension,which currently is broken. Please report any problems you find (see bugs).

The DTM and related work provides faster performance and less accumulation of garbage... though it is an ongoing battle. Brief summary:

• The DTM identifies nodes with 32-bit integer handles. The DTM has many features, including direct character dispatch to SAX2, native DTM iterators and "traversers", multiple document management, etc.
  
  
• Joe Kesselman's CoRoutine parsers, which are in a threaded SAX flavor and in a Xerces parseMore() flavor (no threads). These do away with the "race" conditions that occured in the original code, and should make Xalan much more robust.
  
  
• *Much* more robust XPath itteration. The "waiting" iterators of old are no more, and good riddance. There is stil lots more we want to do with this mechanism. (There is something here called MatchIterators, but it's not being used yet for various reasons. We will be taking advantage of these down the line.)
  
  
• A fair amount of XObject creation reduction. You can now get boolean, number, nodeset, and string values directly from an Expression, instead of going through an XObject.
  
  
• XMLString, which allows us to work with string objects that don't wrap Java's String object. These objects get their character data from an array or Fast String Buffer.
  
  
• Serializers now only do internal buffering if they know they are writing to a FileStream.
  
  
• The variable stack mechanism has been redisigned, so that it is no longer so interpretive, and we believe it is much more robust.
  
  
• Some small amount of stylesheet rewriting (but not yet redundent expression elimination), in particular to reduce full RTF creation and interpretation.

Xalan-Java implements two DTM performance features that you can control with the TransformerFactory setAttribute() method. See DTM performance settings

This release includes a number of bug fixes to Xalan-Java and TrAX. We have also enhanced the ApplyXSLT servlet. It can now be set up to use a compiled Templates object to respond to multiple client transformation requests involving the same stylesheet.

• Committed by jkesselm@apache.org on 03/22/2001
  Modified: java/src/org/apache/xml/utils FastStringBuffer.java
  Committer's log entry: We've reworked the algorithm again. The fixed-chunk-size mode (initial and max. chunk sizes equal) runs essentially unchanged, though with a few cycles less overhead. The variable-chunk-size mode now uses a recursive-encapsulation scheme, where the first chunk may itself be a FastStringBuffer whose total length equals one chunk; every so often we push the existing data down one level and restart with a larger chunk size. The new scheme has been stress-tested and is apparently working. At this writing, however, Xalan uses only the fixed-size mode (initial size equals max size), and no effort has been made to find the optimial values for the tuning parameters. It does appear likely that the best values will vary with usage patterns, but we hope to find a good compromise. I'll probably be putting this aside for a while to work on other things. If someone wants to experiment with varying the block sizes and how frequently they grow, and suggest good performance/memory tradeoff points, go for it!

  Committer's log entry: Patches submitted by Patrick Moore <patrickm@rioport.com> on 03/15/2001 01:25 PM: This proposed change does a number of things: 1. Problem: HTML output method does not uses XML output properties as default. In both org/apache/xalan/templates/output_html.properties and in the java doc for org/apache/xalan/templates/OutputProperties#getDefaultMethodProperties(Strin g) It specifically states that all OutputProperties use the output_xml.properties as a base. In the code this is not true for html. This is now changed to match the comments 2. Problem: unclear IOException. If there was a problem loading the XML properties file. The wrapped exception now will say which file was trying to be loaded. If the file did not exist I was getting a very strange "Stream closed" IOException message. 3. Problem: the streams were not closed after reading the property file. Fixed. 4. Problem: the double-check locking mechanism does not work in Java (see bug #919) <http://www.javaworld.com/javaworld/jw-02-2001/jw-0209-toolbox.html> 5. QUESTION: now if there is a default properties (i.e. output_xml.properties has been loaded) but the expected properties file does not exist a error message will be printed to System.err and the processing will continuing using just the default properties (output_xml.properties) I felt that this is the best behavior. (comment by sboag: I think it's better to throw a runtime exception in this case. but we can discuss this over time. For now the patch was modified to do the runtime exception).

For tooling support. 2) Check to make sure SourceTreeHandler isn't being entered twice, which is related to the cocoon bug from a couple of weeks ago. This will just help diagnose such a problem in the future. 3) Removed the error stack trace print from postExceptionFromThread. 4) Report exception in SourceTreeHandler#endDocument after the join, if we can determine that the posted exception won't be caught elsewhere. 5) removed some catches that simply rethrew the exception (thanks to Patrick Moore <patrickm@rioport.com>). See my note on 3/27/2001 to Patrick for more info on the last two.

  Committer's log entry: Make getClassForName a public method. There are few other places in xalan where Class.forName is used, and this can create problems in some cases where the Thread.getContextClassLoader should be used. getClassForName uses introspection to call getContextClassLoader ( so it works in JDK1.1 ). In ExtensionHandlerGeneral, use the thread loader to find BSF ( it may be possible that xalan is installed in CLASSPATH, but BSF is in a webapp ).

  Modified: java/src/org/apache/xalan/stree SourceTreeHandler.java java/src/org/apache/xalan/transformer TransformerImpl.java
  Committer's log entry: This is the "thread pooling hook". It slightly changes the API used to create and wait for the transform thread. Instead of using threadCreate() and Thread.start() that creates a new thread and thread.join() that waits for a thread to end, we now use a ThreadControler class that has the equivalent methods: - run( Runnable ) - executes a task in a thread. The default implementation is identical with what we had, using new Thread() and start() - waitTread() - waits for a task to end. The default impl. is identical with the previous code, using thread.join(). Someone wanting to use a thread pool for xalan will have to extend the ThreadControler and override the 2 methods, then call setThreadController. Xalan itself doesn't implement a thread pool right now ( for mosts uses it's not even needed - if you just do few transforms for example ), instead a server that runs xalan could plug it's own thread pool.

  Committer's log entry: In indirect response to bug posted by "Thee Boon Hoo" <theebh@newstakes.com> 02/07/2001 09:37 PM "//table[1]" patterns would give one node when they should have given 2, when applied to Boon Hoo's source. "//table[1]" is equivelent to "/descendant-or-self::node()/table[1]", and so must return the first table child of each table-inst element. An optimization was optimizing this to "/descendant-or-self::table, which is fine as long as indexing isn't used. Since we can not tell until runtime if indexing is being used, we have to turn of this optimization for all predicated "//foo[xx]" patterns.

  Modified: java/src/org/apache/xalan/transformer TransformerImpl.java
  Committer's log entry: Fix for bug originally reported by Daryl Beattie <DarylB@screamingmedia.com> on 02/14/2001 04:16 PM. A hang was occuring inside the use of a Result Tree Fragment. When the result tree fragement was being created, the Redirect extension was being called, which called createResultContentHandler which set the ContentHandler in the Transformer, but not in the ResultTreeHandler. Then, Redirect called Transformer#executeChildTemplates( ElemTemplateElement elem, Node sourceNode, QName mode, ContentHandler handler) which saves the reference to the original content handler in the transformer, and then sets the new one by calling setContentHandler, which sets the ContentHandler in the ResultTreeHandler as well as the Transformer. When it tried to restore the old ContentHandler, it restored the value in the ResultTreeHandler to a Serializer, instead of the correct ContentHandler. When transformToRTF then called endDocument on it's resultTreeFragment, the event was sent to the Serializer instead of the SourceTreeHandler, and thus the isComplete flag was not set, and thus the hang. (whew!) The fix is in executeChildTemplates save the value of the resultTreeHandler's contentHandler as well as Transformer's content handler, and restore them both. A more architectual fix could be made, but not without high risk, so I think this is the best and safest way to fix it.

  Committer's log entry: Fix for http://nagoya.apache.org/bugzilla/show_bug.cgi?id=741. 1) ResultTreeHandler now implements the TransformState interface. 2) Queued state such as the current node and the current template is stored as part of QueuedStartElement. Storage will only occur if the ContentHandler implements TransformClient. 3) When state is requested (for instance TransformState#getCurrentElement()), if the queued element is null or not pending (for instance, in a characters event), it will get the state from the transformer, otherwise it will get the state from the queued element. Other fixes were attempted for this problem, including trying to get rid of queueing altogether, and flushing a bit earlier before the state was pushed on the various stacks, but both of these had show-stopping issues (see discussions on xalan-dev). Note that for the moment the ContextNodeList is node cloned as it needs to be in order for TransformState#getContextNodeList.

  Modified: java/src/org/apache/xalan/templates ElemParam.java java/src/org/apache/xpath Arg.java VariableStack.java
  Committer's log entry: The field Arg.isParamVar was attempting to serve two functions: to indicate variable Frame entries which are not currently activated and to indicate Frames containing parameters passed with xsl:with-param. When processing was finished for a node in a node-set, the isParamVar flag was turned on to indicate the Frame slot was available. Unfortunately, this also indicated that the item was passed as a parameter which it wasn't. This fix changes isParamVar into to fields, isAvailable which indicates that the slot is available and isFromWithParam indicating the Frame slot came from an xsl:with-param or a top-level parameter passed in via the tranformerImpl.setParameter() API. I have tested this change against the conformance suite and had no regression. I've also submitted a test case which fails on the existing codebase but works okay after this fix. It is possible that I've missed something with regard to the API setParameter calls but we can fix those if problems are reported.

Also, in the elemAttribute#execute method, checks are made to make sure an element is pending.

  Committer's log entry: The DOM2Helper#isNodeAfter(Node node1, Node node2) method has been fixed so that it no longer does the try/catch thing if one of the nodes doesn't implement DOMOrder, but instead does an instanceof test. In StreeDOMHelper, it overloads this method and *does* do the try/catch business, since almost always both nodes will implement DOMOrder in this case, and this will be faster than an instanceof test. Also, in various classes, I did some stuff to try and make sure that a DOM2Helper wasn't being created and used when a StreeDOMHelper is needed. This addresses http://nagoya.apache.org/bugzilla/show_bug.cgi?id=800 and should give a good performance fix for foreign DOM processing.

There has been a discussion between Gary Peskin in Joe Kessleman on xalan-dev about this, but I hadn't been fully keeping up the the thread that well, and missed it's relation to this problem. I include some of the discussion at the end of this note. I made Xalan be able to compare a "" namespace to null for now, until we get this resolved. The gist of the discussion on xalan-dev regarding this is: >>1. Declare the Xerces-J support of schemas to have a bug and ask that >>Xerces be corrected to always use a null namespace URI to indicate that >>there is no default namespace. Even if the Xerces people change this >>behavior, is this correct? > > Yes. If your description of the problem is accurate (you should probably > submit a more detailed case so it can be reproduced in the lab), this is a > parser/DOM-builder bug.

  Committer's log entry: Made changes for change to API for XalanJ2 TreeWalker, which now requires that the DOM helper be created by the caller.

Release 2.0 includes several bug fixes to the Xalan-Java and TrAX core and to the Xalan-Java 1 compatibility API. We also updated bsf.jar to the Bean Scripting Framework (BSF) release candidate 2.2, which fixes a bug running JPython extensions.

Core bug fixes:

• A threading problem showed up when using multiple processors. We fixed it by using a separate XPathContext object to do whitespace node matches (xsl:strip-space).
  
  
• Fixed a bug running Norm Walsh's DocBook stylesheets by not setting the variable stack position if the FilterExprWalker is not owned by a top-level NodeIterator.
  
  
• Fixed a problem with null namespace being passed from xsl:element. This bug also surfaced while processing DocBook stylesheets.
  
  
• In the interest of stability, we now treat "unknown error in XPath" as a fatal error.
  
  
• Added support in stylesheet processing instructions for "text/xml" and "application/xml+xslt" mime types.
  
  
• Fixed tokenizing of stylesheet processing instructions to allow parameters to be passed to server in href attributes.
  
  
• Fixed a bug passing Transformer creation error messages to ErrorListener when an ErrorListener has been set on TransformerFactory.
  
  
• When using an Exception to instantiate a FactoryConfigurationError (extends Error), we now propagate the Exception message to super().
  
  
• Added defensive code to ElemTemplateElement for handling a null URI.
  
  
• When using an Exception to instantiate a TransformerException (extends Exception), we now propagate the Exception message to super() rather than a generic message.
  
  
• Fixed a bug (the generation of an unwanted entity reference) performing the identity transformation (see Serializing output) with an XML document containing a DOCTYPE declaration.
  
  
• Message manager modified so that the SourceLocator must always be passed in, which will make a major difference in getting line number information.
  
  
• xsl:element's handling of namespace attribute and prefix in name attribute changed so that it no longer manufactures prefixes... it always tries its best to match the prefix entered.
  
  
• Bug fixed with namespace contexts in the stylesheet processor. The bug could cause <a xmlns:a="x"><b> to produce <a xmlns:a="x"><b xmlns:a="x">.
  
  
• Modified processing of xsl:message to enhance it as a debugging aid. Line numbers are now output with each message. If the terminate attribute is true (the default is false) the message is sent to the console, and an exception is thrown with the message "Stylesheet directed termination".
  
  
• In TransformerException, check that the cause != null when checking for a contained exception.
  
  
• Fixed a problem validating non-namespaced attributes and a problem allowing non-namespaced attributes to be children of the stylesheet element.
  
  
• Fixed checking of number of arguments in document() function.
  
  
• Fixed problem with mutation of templates at run time. Templates resolution now takes place during the compose() method.
  
  
• Fixed some minor threading issues in org.apache.xalan.stree (Child, Parent, ElementImpl, SourceTreeHandler).
  
  
• Synchronized TrAX API functions subject to mutation to prevent mutation during a transformation.
  
  
• Fixed bug reported by Jano Elovirta: substring() was returning an error if the start index is larger than the string.
  
  
• Set StringKey.toString() to return the underlying String (m_str), thus avoiding a potential symmetry problem with the equals() method reported by Ito Kazumitsu.
  
  
• In response to note from Ito Kazumitsu, changed Java encoding name "EUCJIS" in FormatterToXML to "EUC_JP".
  
  
• When Xalan creates a FileOutputStream, it now closes the stream before exiting.
  
  
• Fixed handling of an exception that can be thrown while building a DOM.
  
  
• Fixed a problem reported by Dimitry Voytenko serializing compiled stylesheets.
  
  
• For support of applets, modified TransformerFactory System.getProperty() calls to catch SecurityExceptions.
  
  
• Fixed a bug reported by Krishna Mohan Meduri setting output properties.
  
  
• Fixed error recovery when xsl:element encounters a bad name or unresolvable prefix.
  
  
• Added AbstractMethodError handling to existing NoSuchMethodError handling as a fallback to the XMLReaderFactory for XML parsers that do not implement the JAXP parsers interface for creating an XMLReader
  
  
• Fixed bug with cloned iterators reported by Tim Sean.
  
  
• Fixed null pointer exception that could occur with getValue("xxx").
  
  
• Fixed bug reported by Tim Sean handling the xml:space attribute.

Bug fixes in the Xalan-Java 1 compatibility API:

• Fixed ProblemListener (for processing error messages) to derive from Xalan-Java 2 ErrorHandler.
  
  
• Fixed evaluation of stylesheet string parameters to conform to Xalan-Java 1 behavior (expressions for Xalan-Java 1 vs. String objects for Xalan-Java 2).
  
  
• Added XPathSupport and XPathSupportDefault, and fixed the derivation of XObject sub-types (XString, etc.).
  
  
• Fixed bug with XSLTProcessor process(xmlIn, null, out) method so that it uses the StylesheetRoot (if one exists) that has been created with the processStylesheet() method.

For a list of tasks in the Xalan-Java 2 To-Do list that have been completed, see Tasks completed.

Xalan-Java 2.0.D07 incorporates a Xalan-Java 1 compatibility jar, some performance enhancements, and a number of bug fixes for bugs found in version 2.0.D06.

• Fixed handling of disable-output-escaping="no". Previously, once it was turned on, it could not be turned off.
  
  
• Fixed a bug with whitespace handling where Xalan was incorrectly checking for whitespace stripping before collation of multiple whitespace events into a single text node.
  
  
• Whitespace stripping wasn't working with input DOMs before. This is now fixed.
  
  
• Fixed many exception handling problems and problems with error reporting.
  
  
• Fixed a bug resetting parameters in Transformer clearParameters().
  
  
• Fixed a bug where CDATA sections were not matching the text() node test.
  
  
• Made better memory allocation problem with result tree fragments.
  
  
• Made result tree fragment parsing of numbers consistent with strings.
  
  
• Exceptions thrown from extensions should now be properly reported via the error listener.
  
  
• Fixed hard-coded stack dump set off by m_reportInPostExceptionFromThread variable.
  
  
• Fixed intermittent threading problem with text nodes being dropped.
  
  
• Fixed problem with variable evaluation inside of union expressions.

We have fixed the bugs reported in Xalan-Java 2.0.D05. Along with several other enhancements, we have also fixed a number of bugs found by testing and our users:

• Fixed some threading problems and improved support for handling Exceptions thrown in a secondary thread.
  
  Note: To support incremental output, Xalan-Java performs the transformation in a second thread while building the source tree in the main thread.
  
  
• Fixed problems encountered in piping (utilizing transformation output as input for another transformation).
  
  
• Fixed problems handling attributes and adding attributes to result tree.
  
  
• Added defensive checking for null entities, null namespaces, and empty strings passed in for URIs and local names.
  
  
• We now conform to the SAX convention of representing null namespaces with empty strings.
  
  
• Fixed a bug encountered evaluating a variable in a predicate expression applied to child nodes.
  
  
• Changed names of serializers from FormatterToXxx to SerializerToXxx. See Package org.apache.xalan.serialize.
  
  
• Improved debugging support in a number of areas.

All of the bugs reported in Xalan-Java 2.0.D01 have been fixed. The remainder of this section discusses two changes that we believe are of particular importance:

TrAX

The Transformation API for XML (TrAX) that Xalan-Java 2 implements has undergone substantial revisions since the release of Xalan-Java 2.0.D01. TrAX has joined the Java API for XML Parsing (JAXP) as part of the Sun® Java Specification Request 63. Accordingly, the TrAX package names have changed. The conceptual organization has also changed somewhat: The primary transformation interfaces are defined in javax.xml.transform, with concrete classes for managing stream input/output, SAX parsers and ContentHandler, and DOM parsers and DOM trees in javax.xml.transform.stream, javax.xml.transform.sax, and javax.xml.transform.dom. For more information, see TRaX (Transformation API for XML), and review Usage Patterns.

Output properties

The handling of xsl:output properties has changed: org.apache.xalan.serialize.OutputFormat and apache.xalan.templates.OutputFormatExtended were removed and replaced with org.apache.xalan.templates.OutputProperties. The SerializerFactory getSerializer() method now takes Properties rather than a String indicating the output method. You can replace getSerializer("xml"), for example, with getSerializer(OutputProperties.getDefaultMethodProperties("xml")).

HTML, XML, and text xsl:output properties are specified in property files in org.apache.xalan.templates: output_html.properties, output_xml.properties, and output_text.properties.

You can start using the output properties defined in these files in your stylesheets. For example, you can turn URL escaping off in HTML output with
{http\u003a//xml.apache.org/xslt}use-url-escaping=no
and you can control indenting with
{http\u003a//xml.apache.org/xslt}indent-amount=n

The colon after the "http" protocol must be escaped.

Character-to-entity mapping is specified in org.apache.xalan.serialize: HTMLEntities.res and XMLEntities.res. You can override entity ref mapping from a stylesheet. For example:

	<?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xslt" version="1.0"> <xsl:output xalan:entities="myentities.ent"/> <xsl:template match="/"> <out>&#125;</out> </xsl:template> </xsl:stylesheet>

=== myentities.ent ===

	quot 34 amp 38 lt 60 gt 62 lala 125

The output is:

	<?xml version="1.0" encoding="UTF-8"?> <out>&lala;</out>

See also Setting output properties in your stylesheets.
