NodeRefList to DOM_Nodes or DOM_NodeList?

[sk ask <ar...@yahoo.com>]

Hi,
  I am trying to get the selectListNodes method to
work.
Having a tough time returning a set of nodes
(converting from xalanNode to DOM nodes). Here is
the code. Can someone please point me to some
resources
or solution? Always get a crash in vector destructor


bool XMLReader::selectNodes(const TCHAR* xpathExpr,
std::vector<DOM_Node>& nodes)
{
	// Set up a XercesParserLiaison and use it to wrap
the DOM_Document
	// in a XalanDocument.
	XercesDOMSupport   theDOMSupport;
	XercesParserLiaison	theParserLiaison(theDOMSupport);

theParserLiaison.setDoNamespaces(m_parser->getDoNamespaces());
	XalanDocument* theDoc =
theParserLiaison.createDocument(getDocument());

	assert(theDoc);

	XPathEvaluator	theEvaluator;

	// OK, let's find the context node...
	NodeRefList const	theContextNodes =
		theEvaluator.selectNodeList(
		theDOMSupport,theDoc,
		XalanDOMString(xpathExpr).c_str(),
		theDoc->getDocumentElement());

	nodes.clear();	
	int numNodes = theContextNodes.getLength();
	if(numNodes)
	{
		nodes.reserve(numNodes);
		const XercesDocumentBridge* bridge=
theParserLiaison.mapDocument(theDoc);
		if(bridge)
		{
			for(int i=0;i<numNodes;++i)
			{
				DOM_Node aNode =
bridge->mapNode(theContextNodes.item(i));								
				nodes.push_back(aNode);
			}
			return true;
		}
	}			
	return false;
}

//usage
void TestXmlReader()
{
	CimfXMLReader reader;

reader.parseDoc("c:/temp/wpp/wpp3.xml",true,true,true);
	bool retVal;
	std::vector<DOM_Node> nodes;
	if(reader.selectNodes("//x:Model",nodes))
	{
		std::vector<DOM_Node>::iterator it = nodes.begin();
		for(;it != nodes.end();++it)
		{
			tstring str = reader.getAttValue("Type", (*it));			
			AfxMessageBox( str.c_str());
			
			*it = 0;
		}
	}
	nodes.clear();
}
