You supplied a GSSAXHandler object.
If a GSSAXHandler object is supplied, it is assumed to handle the 
elements found in the document
on the fly, and no GSXMLDocument is created.  If you want to create a 
GSXMLDocument and then
examine its contents, you should use [GSXMLParser parserWithData:] to 
create the parser.
