Loading XML from CPP

Right...

 I've got my facts wrong. This code works fine with Mozilla 1.4.2 and 1.7.2.

 However, and this is why I got confused: I have put this code into an XPCOM Compoment. If the XPCOM component is loaded from a XUL dialog: everything is cool... but if this is loaded from a JS started with xpcshell, then it doesn't quite work anymore. Actually, the document loading work, but I cannot query anything using nsIDOMXPathEvaluator...

 any ideas ???

 Thanks

 Hi,
 
 What is the best/recommended way of loading XML from a cpp mozilla application?
 
 {
 NS_DEFINE_CID(kXMLDocumentCID, NS_XMLDOCUMENT_CID);
 nsCOMPtr<nsIDOMXMLDocument> pXMLDoc;
 do_CreateInstance(kXMLDocumentCID, &rv);
 pXMLDoc->SetAsync( false );
 PRBool retval = false;
 NS_NAMED_LITERAL_STRING(url , "http://mysite/myxml" );
 pXMLDoc->Load( url , &retval );
 }
 
 Seems to work, but then when I use the nsCOMPtr<nsIDOMXPathEvaluator> to query the XML node, I always get an empty result set(stepped down to no document owner....) So i assume this is not the way to do it anymore (used to work with Mozilla 1.4.2, but not with mozilla 1.7.2).
 
 What is the best/recommented practice to do this ?
 
 Thanks
 
 JM
