Xerces

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.

The Xerces Java Parser 1.2.0 supports XML 1.0, and can be used for building XML-compatible Web servers; building the next generation of XML-based vertical applications; creating XML editors; ensuring the integrity of XML data; and building global XML applications.

Xerces-C is an XML parser written in a portable subset of C++. Xerces-C allows applications to read and write XML data. A shared library facilitates parsing, generating, manipulating, and validating XML documents. Other features include conformity to XML 1.0; tracking of latest DOM and SAX specifications; programmatic generation and validation of XML; pluggable catalogs, validators and encodings; and customizable error handling.

XML4P includes a collection of Perl wrapper objects that internally use their XML4C counterparts for high-performance, scalable and localizable DOM parsing. Features include programmatic generation and validation of XML; conformity to DOM specifications; and customizable error handling.
