If VAR is your root element, then the other element nodes are children
of it.  If not and there's a different root element, then all these
element nodes are siblings of it.

Nodes are arranged in a hierarchical structure:

	VAR element [with attributes]
	 DESCRIPTION element
	  text node ("EngineStart Leak")
	 STATENAME element
	  text node ("good")
	 STATENAME element
	  text node ("bad")

Traverse the tree by looking at the childNodes attribute (Python
attribute, not XML attribute).
