selectSingleNode

[Arigapudi, Shyam]

Hi,
 I already have a DomDocument from xerces.

 I saw the stub about converting xalandocument to xerces and viceversa.
 I am stuck at trying to convert the the XObjectPtr to a xalanNode. Then I
want
to map it back to Dom_node and go on.
 Here is a simple function that I am trying to write and it does not work.
Could
someone help me out. Thanks.

DOM_Node aNode;
        // Set up a XercesParserLiaison and use it to wrap the DOM_Document
        // in a XalanDocument.
        XercesDOMSupport   theDOMSupport;
        XercesParserLiaison     theParserLiaison(theDOMSupport);
        XalanDocument* theDoc =
theParserLiaison.createDocument(getDocument(),false,true);

        assert(theDoc);
        XPathEvaluator  theEvaluator;

        // OK, let's find the context node...
        XalanNode* const        theContextNode =
                theEvaluator.selectSingleNode(
                theDOMSupport,theDoc,
                XalanDOMString("/").c_str(),
                theDoc->getDocumentElement());
        if(theContextNode != 0)
        {
                // OK, let's evaluate the expression...
                const XObjectPtr        theResult(
                        theEvaluator.evaluate(
                        theDOMSupport,
                        theContextNode,
                        XalanDOMString(xpathExpr).c_str(),
                        theDoc->getDocumentElement()));
                
                assert(theResult.null() == false);
                const XercesDocumentBridge* bridge=
theParserLiaison.mapDocument(theDoc);
                if(bridge)
                {
                        //How to get the xalanNode from the Evaluator
                        const XalanNode *xnode = (const
XalanNode*)theResult.get();
                        XalanDOMString str = xnode->getNodeValue();
                        aNode = bridge->mapNode( xnode);
                }
        }
