XML Parser for Java 4.0.5 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.

Xerces 2 is a fully conforming XML Schema processor. For more information, refer to the XML Schema Limitations page.

Xerces 2 also provides a partial implementation of Document Object Model Level 3 Core, Abstract Schemas and Load and Save Working Drafts. For more information, refer to the DOM Level 3 Implementation page.

Please use BugZilla to report any bugs that you find.

You can find the latest Xerces 2 jars here.

Changes from Previous Release
 

The XML Parser for Java 4.0.5 introduced some changes to the Xerces Native Interface. The following list enumerates the important changes:

  • Added an interface, XMLResourceIdentifier, for describing the physical location of XML resources to the core XNI interfaces. This interface is used in grammar caching and entity resolution.
  • Updated XMLEntityResolver, XMLLocator, XMLDocumentHandler, XMLDocumentFragmentHandler, and XMLDTDHandler to use XMLResourceIdentifier interface.
  • Added Augmentations to XMLDTDHandler, XMLDocumentFragmentHandler, and the XMLDTDContentModelHandler interfaces

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. It includes a completely redesigned and rewritten XML Schema validation engine. Applications using only the standard interfaces such as JAXP, DOM, and SAX should not see any differences.
