Call to XercesDocumentWrapper method mapNode results in a pure virtual method called error

[T A]

Hi,

 

I am trying to use the XercesDocumentWrapper method mapNode to convert a Xalan Node to a Xerces Node. The Xalan node is obtained from a NodeRefList object via the item method.

 

The code is aborting at the call to map node and I see an error message "pure virtual method called"

 

Below is a code fragment. I would appreciate any help. Am I missing some kind of macro declaration or object?

 

 

        XALAN_CPP_NAMESPACE_USE
        XALAN_USING_XERCES(XMLException)
        XercesDOMSupport theDOMSupport;

        try
        {
                if (nodeList)
                {
                        DOMDocument* xercesDocument = sourceDocument->getDocument();

                        DOMNode* indexedNode;

                        XercesDocumentWrapper xalanDocument(xercesDocument);

                        

                        const NodeRefList::size_type nodeListLength = nodeList->getLength();
                        ctrace << "Node List Length is" << nodeListLength << endl;

                         XalanNode* the_node = nodeList->item(index);

 

                        if(the_node)
                             indexedNode = (DOMNode*)(xalanDocument.mapNode(the_node)); 

 

 

Thanks,

Ted
