TXMLParser is an abstract class which interfaces with Libxml2.

Libxml2 is the XML C parser and toolkit developed for the Gnome project. The libxml library provides two interfaces to the parser, a DOM style tree interface and a SAX style event based interface. TXMLParser is parent class of TSAXParser and TDOMParser, which are a SAX interface and DOM interface of libxml.
