extends org.htmlunit.cyberneko.xerces.parsers.AbstractSAXParser
implements org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler, org.htmlunit.cyberneko.HTMLTagBalancingListener, HTMLParserDOMBuilder
    INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.
    The parser and DOM builder. This class subclasses Xerces's AbstractSAXParser and implements the ContentHandler interface. Thus all parser APIs are kept private. The ContentHandler methods consume SAX events to build the page DOM
