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).[1]

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.[2]
Language Release Date Version
Java 2022-01-24 2.12.2
C++ 2020-04-10 3.2.3
Perl 2014-04-30 2.7.0
