	 *	The DomParser is a close-to (but not entirely)
	 *	conforming XML parser based on regular
	 *	expressions.  It will take any XML fragment
	 *	and return a lightweight JS structure that is
	 *	similar to (but not exactly) the DOM specification.
	 *
	 *	Getter and setter methods are NOT available; the goal
	 *	was to keep the resulting object model entirely JS-like.
	 *
	 *	All node types but document fragments are supported;
	 *	all nodes support getElementsByTagName and 
	 *	getElementsByTagNameNS (with short names byName and 
	 *	byNameNS).  The document node supports getElementById
	 *	(byId), and all nodes support a supplimental
	 *	childrenByName/childrenByNameNS method as well.
	 *
	 *	The object model is intended to be a READONLY format;
	 *	mutation events are NOT supported, and though you
	 *	can change properties on a node-by-node basis, certain
	 *	operations are not supported (such as changing the ID 
	 *	of an element).
