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
[edit]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]

Apparently, the parser was named after the now extinct Xerces blue butterfly, a native of the San Francisco peninsula.

XML::Xerces is the Perl API to the Apache project's Xerces XML parser. It is implemented using the Xerces C++ API, and it provides access to most of the C++ API from Perl.
