public class XMLHelper

extends DefaultHandler

Utilities to convert XML within strings to property lists.

This builds a hashtable from some xml, which in simple cases will then allow us to pull out the values we need. Can be used where a custom handler implementing its own startElement etc methods is overkill and you couldn't be bothered to use DOM or SAX parsing.

The document is a hashtable, as is each element. Within an element, attributes or child elements are put in as keys of whatever they are called. If an element has more than one child of the same type, instead of a hashtable under that key there will be a vector of hashtables.
