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.
Because it is based on Xerces-C, XML::Xerces provides a validating XML parser
that makes it easy to give your application the ability to read and write XML
data. Classes are provided for parsing, generating, manipulating, and
validating XML documents. XML::Xerces is faithful to the XML 1.0 recommendation
and associated standards (DOM levels 1, 2, and 3, SAX 1 and 2, Namespaces, and
W3C XML Schema). The parser provides high performance, modularity, and
scalability, and provides full support for Unicode.
XML::Xerces implements the vast majority of the Xerces-C API. The exception is
some functions in the C++ API which either have better Perl counterparts (such
as file I/O) or which manipulate internal C++ information that has no role in
the Perl module.
