append new xalanNode taken from other Xalan Document to my XalanN ode

["Tankel, Ifat" <If...@icomverse.com>]

Hi
I want to take new XalanNode *from otherXalanDocument and append it to old
XalanNode in myXalanDocument
the XalanNode I have is XercesElementBridge * and that the XalanDocument is
XalanDocumentBridge *

when I wrote 
void myDom::addNode(string thisDomXpath,myDom & otherDom ,string
otherDomXpath){
   XalanNode * newNode=otherDom.getNode(_evaluatorI,otherDomXpath); //
getNode use evaluator to retrieve XalanNode which is XercesElementBridge
   XalanNode * oldNode=getNode(_evaluatorII,thisDomXpath); 
   oldNode->appendChild(_xalanRealDoc[0]->importNode(newNode,true)); //
_xalanRealDoc[0] is XalanDocumet * returned by
XercesParserLiaison->createDocument(DomDoc) 
}
I got exception not supported // because XalanDocumentBridge::importNode is
not supported   ...... so I wrote 

void myDom::addNode(string thisDomXpath,myDom & otherDom ,string
otherDomXpath){
   XalanNode * newNode=otherDom.getNode(_evaluatorI,otherDomXpath); 
   XercesDocumentBridge * newXercesDoc= dynamic_cast <XercesDocumentBridge
*> (otherDom.getRealXalanDoc());
   DOM_Node newDOMNode= newXercesDoc->mapNode(newNode);

   XalanNode * oldNode=getNode(_evaluatorII,thisDomXpath);
   XercesDocumentBridge * oldXercesDoc=dynamic_cast <XercesDocumentBridge *>
(_xalanRealDoc[0]);
   DOM_Node oldDOMNode=oldXercesDoc->mapNode(oldNode);

   oldDOMNode.appendChild(_domDocument->importNode(newDOMNode,true));
    // to see my changes I need the next steps
   _parserLiaison->destroyDocument(_xalanRealDoc[0]);
   _xalanRealDoc[0]=_parserLiaison->createDocument(*_domDocument);
} 
must it be like that ? Is there any other way to do it?
Regards
