Soup Parser

This module provides a very lenient HTML/XML lexer. The SoupLexer class is initialized with a listener object, which receives all low level events (like starttag, endtag, text etc). Listeners must implement the ListenerInterface.

On top of the lexer there's SoupParser class, which actually implements the ListenerInterface itself (the parser listens to the lexer). The parser adds HTML semantics to the lexed data and passes the events to a building listener (BuildingListenerInterface). In addition to the events sent by the lexer the SoupParser class generates endtag events (with empty data arguments) for implicitly closed elements. Furthermore it knows about CDATA elements like <script> or <style> and modifies the lexer state accordingly.

The actual semantics are provided by a DTD query class (implementing DTDInterface.)
