Xerces2 Java Parser 2.0.0 (beta3) Release
 

Welcome to the future! Xerces2 is the next generation of high performance, fully compliant XML parsers in the Apache Xerces family. This new version of Xerces introduces the Xerces Native Interface (XNI), a complete framework for building parser components and configurations that is extremely modular and easy to program.

The Apache Xerces2 parser is the reference implementation of XNI but other parser components, configurations, and parsers can be written using the Xerces Native Interface. For complete design and implementation documents, refer to the XNI Manual.

Note: Since this is a beta release, bugs are to be expected. Please use BugZilla to report any bugs that you find.


Features of This Release
 

The Xerces2 Java Parser 2.0.0 (beta3) supports the following standards and APIs:


Changes from Previous Release
 

This is the first Xerces2 release to include support for validating XML documents against XML Schema grammars. The XML Schema validation engine was completely redesigned and rewritten for Xerces2. Therefore, the XML Schema support in this release should be considered alpha.

This release also introduces some changes to the Xerces Native Interface. The following list enumerates the important changes:

  • Filter interfaces were added to simplify the implementation and use of pipeline components that consume and produce document and DTD events.
  • Getter methods were added to the XMLParserConfiguration interface to query the registered handlers, resolvers, etc.
  • The XMLDTDHandler#internalEntityDecl method was modified to include the non-normalized literal value of the internal entity.
  • The XMLAttributes interface was simplified by removing the methods relating to entities appearing in attribute values. The non-normalized attribute value in conjunction with the non-normalized value for internal entity declarations makes these methods unnecessary.

For a more complete list of changes, refer to the Release Information page.


Changes from Xerces 1.x
 

Xerces2 is a nearly complete rewrite of the Xerces 1.x codebase in order to make the code cleaner, more modular, and easier to maintain. Applications using only the standard interfaces such as JAXP, DOM, and SAX should not see any differences.
