Xerces2 Java Parser 2.5.0 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.

Xerces2 is a fully conforming XML Schema processor. For more information, refer to the XML Schema page.

Xerces2 also provides an experimental implementation of the Document Object Model Level 3 Core and Load/Save Working Drafts and provides a partial implementation of the XML Inclusions (XInclude) W3C Candidate Recommendation.

Xerces2 is now able to parse documents written according to the XML 1.1 Candidate Recommendation, except that it does not yet provide an option to enable normalization checking as described in section 2.13 of this specification. It also handles namespaces according to the XML Namespaces 1.1 Candidate Recommendation, and will correctly serialize XML 1.1 documents if the DOM level 3 load/save API's are in use.

Features of This Release

The Xerces2 Java Parser 2.5.0 supports the following standards and APIs:

Backwards compatibility

According to the DOM Level 3 specification and DOM Level 2 errata the createElementNS and createAttributeNS methods convert empty string namespaceURI to null. Please, let us know if this change affects your application.

Changes from Previous Release

The Xerces2 Java Parser 2.5.0 fixes bugs and adds the following functionality:

  • Added partial implementation for W3C XInclude specification.
  • Added implementation for exposing XML Schema annotations.

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.
