Xerces2 Java Parser 2.2.0 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.

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

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

Before reporting a bug in BugZilla, please read the Bugzilla FAQ.

You can find the latest Xerces 2 jars here.

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.
