validating XML parser library for C++ 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. Xerces-C++ is faithful to the XML 1.0 recommendation and associated standards (DOM 1.0, DOM 2.0, SAX 1.0, SAX 2.0, Namespaces, XML Schema Part 1 and Part 2). It also provides experimental implementations of XML 1.1 and DOM Level 3.0. The parser provides high performance, modularity, and scalability.
