XalanDocument and DOMDocument Interchange

[Manoj Kumar Chitlangia]

Hi,
I have the following declarations:

  xalanc_1_10::XalanDocument *xalan_document;
  xercesc_2_7::DOMDocument *dom_document_;

I have these statements afterwards to initialize these:

xalan_document = parser_liaison_.parseXMLStream(input_source);
XalanNode* result = evaluator.selectSingleNode(
                        dom_support_,
                        xalan_document_,
                        XalanDOMString(xpath).c_str(),
                        prefix_resolver);

XercesParserLiaison xerces_parser_liaison;
XercesDocumentWrapper *document_wrapper =
xerces_parser_liaison.mapDocumentToWrapper(xerces_parser_liaison.createDocument(dom_document_,
true, true, true));

I want to get a DOMNode out of the XalanNode* result, but going by the
following method I get the Exception WRONG_DOCUMENT_ERR

const DOMNode *dom_node = (const DOMNode*)document_wrapper->mapNode(result);

since result if owned by xalan_document but the XercesDocumentWrapper was
created for dom_document which is a DOMDocument.

Statements like these give null:

XercesDocumentWrapper *document_wrapper =
xerces_parser_liaison.mapDocumentToWrapper(xalan_document)

Please tell me how should I go about to get a DOMNode out of the
XalanNode* result.

Thanks,
-Manoj
