Xerces-C++ validating XML parser
Xerces-C++ is a validating XML parser written in a portable subset of C++.
Xerces-C++ makes it easy to give your application the ability to read and
write XML data. A shared library is provided for parsing, generating,
manipulating, and validating XML documents.
The parser provides high performance, modularity, and scalability. Source
code, samples and API documentation are provided with the parser. For
portability, care has been taken to make minimal use of templates, no RTTI,
and minimal use of #ifdefs.
