XPathAPI and namespaces

[Sol Mayer-Orn]

I'm having a problem with XPATH and namespaces.
Could anyone please help ?

I'm using apache XPathAPI, with java 1.4.
It works fine as long as there are no namespaces.
Unfortunately, when adding namespaces to the xml, XPathAPI fails to find the desired element (returning null).

String xml=
   "< ns1:body xmlns:ns1='tempuri' >" +
        "< ns1:status > OK < / ns1:status >" +
   "< / ns1:body >";
 
// Parse the above xml string:
DocumentBuilder docBuilder= DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc=docBuilder.parse(new InputSource(new StringReader(xml)));
Node root=doc.getDocumentElement();
 
// Tell XPathAPI that "ns1" is the prefix for the "tempuri" prefix:
Element nsResolverNode=doc.createElement("NamespaceResolver");
nsResolverNode.setAttribute("xmlns:ns1", "tempuri");
 
// This returns "null", instead of the desired < status > element... why ?
Node subNode = XPathAPI.selectSingleNode(root, "ns1:body/ns1:status", nsResolverNode);
 

What am i doing wrong ? Do you know of a better way to do it ?
Thanks.

Thanks.

If you do like this, does it work?

Node subNode = XPathAPI.selectSingleNode(root, "tempuri:body/tempuri:status", nsResolverNode);

Thanks for replying... unfortunately this suggestion doesn't work
(it gives a runtime error message, which actually makes sense here: "prefix must resolve to a namespace: tempuri" ).
