Apache Xerces

In computing, Xerces is Apache's collection of software libraries for parsing, validating, serializing and manipulating XML. The library implements a number of standard APIs for XML parsing, including DOM, SAX and SAX2. The implementation is available in the Java, C++ and Perl programming languages.

The name "Xerces" is believed to commemorate the extinct Xerces blue butterfly (Glaucopsyche xerces).

Xerces language versions
There are several language versions of the Xerces parser:
 * Xerces2 Java, the Java reference implementation
 * Xerces C++, a C++ implementation
 * Xerces Perl, a Perl implementation. This implementation is a wrapper around the C++ API.

Features
The features supported by Xerces depend on the language, the Java version having the most features.
