High-level non-validating XML parser component that is free for both commercial and non-commercial use. (1) Load/save XML files to an in-memory document object model (DOM). (2) Add name/value attribtes to nodes. (3) Compress nodes or entire sub-trees using in-memory Zip compression. (4) AES encrypt the content of a node. (5) Numerous methods for iterating over the nodes in a document. (6) Numerous methods for searching and sorting nodes in a document. (7) API designed to make it easy to do frequently encountered tasks when working with XML. (8) Makes it easy to handle binary data (such as image data) within XML files.

Redland is a library that provides a high-level interface for RDF allowing the model to be stored, queried and manipulated. Redland implements each of the RDF model concepts in its own class so provides an object based API for them. Some of the classes providing the parsers, storage mechanisms and other elements are built as modules that can be added or removed as required. Features include: A modular, object based library written in C, C and Perl APIs for manipulating the RDF Model and parts - Statements, Resources and Literals, Parsers for importing the model from RDF/XML syntax, Storage for models in memory and on disk via Berkeley DB, Query APIs for the model by Statement (triples) or by Nodes and Arcs,and Statement Streams for construction, parsing, de/serialisation of models.

XML4C consists of three shared libraries (two code and one data) that provide classes for parsing, generating, manipulating, and validating XML documents. XML4C is faithful to the XML 1.0 Recommendation and associated standards (DOM 1.0, SAX 1.0, DOM 2.0, SAX 2.0, Namespaces). XML4C also supports a subset of the W3C Schema language (see the documentation for supported features). Source code, samples, and API documentation are provided with the XML4C parser.
