- * 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).
