This is an XML parser, based upon NSXMLParser, that parsers a well-formed XML feed into a structure of ParserNode objects. The intent is to provide a generalized parser (not hard-coded for any particular feed), that returns data in a structure more robust than simply a combination of NSDictionary and NSArray objects.
This is a work-in-progress so use at your own risk. But it illustrates how to use NSXMLParser to parse an XML feed into a tree-like structure that can be easily navigated.
For more information, see the XMLNodeParser documentation.
