Xerces (the name comes from the Xerces blue butterfly) is a set of parsers compatible with Extensible Markup Language (XML). (A parser is a program that analyzes and organizes formal language statements into a usable form for a given purpose.) Xerces parsers are available for Java and C++, implementing World Wide Web Consortium (W3C) XML, Document Object Model (DOM), and Simple API for XML (SAX) standards.
All of the Xerces parsers are modular and configurable. A Perl wrapper is provided for the C++ version; this allows access to a fully-validating XML parser from Perl. It also provides access to Unicode strings.
