Using Xerces in a COM Object

[Gareth Reakes <ga...@decisionsoft.com>]

Hello all,
	I am creating a simple in process COM object compiled as a dll. 
The following code causes abnormal program termination.

If the createElementNS() line is removed then everything is OK. Any help
is appreciated - first time using COM!!



STDMETHODIMP CXEngine::execute(BSTR uri, BSTR dataDoc, BSTR *result)
{
	try{
		XMLPlatformUtils::Initialize();
	}
	catch (const XMLException& eXerces) {
	    char *pMsg = XMLString::transcode(eXerces.getMessage());
	    fprintf(stderr, "Xerces exception caught: %s\n", pMsg);
		delete pMsg;
        }

	DOMString DataDocQName = L"xs:__data__";
	DOMString DataDocNamespaceURI = L"http://www.xmlscript.org/";
	DOM_DocumentType DataDTD;

	DOM_Document data = factory.createDocument(DataDocNamespaceURI,
DataDocQName, DataDTD);

	DOM_Element child1 = data.createElementNS("", "child1");

	return S_OK;
}

Sorry I didnt make myself clear. I am not using Xerces-COM. I have an
application which uses xerces-c and works. I want to turn it into a COM
object. When I tried this it did not work so I wrote the few lines of code
I posted in my previous messgae - which also fails.

When functionality is exposed by MSXML that isn't implemented by Xerces-C,
Xerces-COM returns E_NOTIMPL.  In this case, you are making a call to a DOM
2 method and Xerces-C hasn't implemented DOM2.
