This is not how it works. loadXML() returns S_FALSE on load failure as 
well, so you have to test strictly for S_OK, or check VARIANT_BOOL 
argument. You can probably add a test when invalid xml stream is 
received to see how _get_responseXML() behaves, e.g. does it return 
S_FALSE and a valid IDispatch or does it fail and return NULL.

Also I don't think it's a good idea to trace xml contents.
