If the next web request returns an XML document, the document will be parsed by the XML dom parser and the handle to the document will be stored in hDocument. If there is no document that can be parsed, the handle will be 0.
nOccurrence specifies that the nOccurrence'd document of the next request that matches the content type should be parsed. Default value is 1.
If sContentType is defined only documents of that content type will be parsed. Default value is "text/xml".
