PHP XML Classes

Release Notes: class_xml_check (v1.0), a class to check if a file/URL is well formed was added. It can report error details (message, line number, column number) if the file is not well formed or statistics about the XML document if it is well formed (size, number of elements, text sections, size of text sections, and attributes).

Release Notes: The RDQL_db and RDQL_query_db classes were added. RDQL_db is a class to store and retrieve (delete) RDF documents to and from a MySQL database. RDF documents are parsed and then stored as RDF statements. The second class, RDQL_query_db, implements the RDQL language for RDF documents stored with the first class. Since documents are parsed when stored, the RDQL class doesn't parse the documents, which improves the querying speed.

Release Notes: The RDQL class was added. This is a generic RDQL engine and an implementation of the engine to query RDF documents from files or URLs. The documentation for all the packages was updated. Bugfixes and minor cosmetic changes were made.

Release Notes: A path parser class was added. This is a generic XML parser, based on Expat, that lets you associate PHP functions with XML elements indicating a path (for example, /foo/data/name). The user's functions will be called each time such an element is found by the parser, passing the element name, attributes, and content (text or a XML fragment) as arguments.

Release Notes: A class to parse RDDL documents was added. The class can parse RDDL documents, extracting resource elements that can then be obtained. The class can parse all RDDL valid documents from URLs or files.
