appendChild in Xalan

[Shang, Crystal]

Hi,

I'm trying to create a DOM tree in memory and dump the result to an XML file
using FormatterToXML and FormatterTreeWalker. Somehow when I call
appendChild to append the result of XPath evaluation( ELEMENT_NODE ) to the
tree, the code crashes:

{
        ...
        XercesDOMSupport        domSupport;
        XercesParserLiaison     parserLiaison(domSupport);

                XalanDocument*          xDocument   =
parserLiaison.createDocument();
          
                XalanElement *          parentEle  =
xDocument->createElement(XalanDOMString("Parent"));
    
                xDocument->appendChild( parentEle );            
                parentEle->appendChild((XalanNode *)theNode);  <--- crashes
here         
        ...
}   

theNode is a valid element node retrieved from the nodelist of XPath
evaluation, if I just use FormatterTreeWalker::traverseSubtree(theNode), I
am able to save this into a valid XML file. However, when I add this to be a
part of a DOM tree, it crashes. Can you let me know what I should do?

Thanks in advance,

- Crystal
