Incomputing,Xerces isApache's collection ofsoftware libraries for parsing, validating, serializing and manipulatingXML. The library implements a number of standardAPIs for XML parsing, includingDOM,SAX and SAX2. The implementation is available in theJava,C++ andPerl programming languages.
The name "Xerces" is believed to commemorate the extinctXerces blue butterfly (Glaucopsyche xerces).[1]
There are several language versions of the Xerces parser:
| 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 |
The features supported by Xerces depend on the language, the Java version having the most features.

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.
