Hi, i'm using Xerces 3.0.0.b1 and i can't get xpath to work
Basically i'm parsing a file with XercesDOMParser

then i grab the stuff to a DOMDocument

DOMDocument* domDoc = xdomp->getDocument();

initialise the xpath stuff

DOMXPathEvaluator* xpath = (DOMXPathEvaluator*) domDoc;
DOMXPathResult *xpres;

and finally in a try/catch i try to get the result

xpres = (DOMXPathResult *)
xpath->evaluate(XMLString::transcode("packet/group/offset"),
domDoc->getDocumentElement(), NULL, DOMXPathResult::ANY_TYPE, NULL);
  

The XPath processing can only return nodes, so the types that are 
supported are DOMXPathResult::FIRST_ORDERED_NODE_TYPE, 
DOMXPathResult::ORDERED_NODE_SNAPSHOT_TYPE, 
DOMXPathResult::ANY_UNORDERED_NODE_TYPE and 
DOMXPathResult::UNORDERED_NODE_SNAPSHOT_TYPE

However i always get a message saying: "The requested result type is not
supported".

Any help?

Thanks
