XML validation against DTD using loadGrammar

Hi All,

I asked this question in c-dev list, but not getting
satisfying answers, so I post it here:

I am using Xerces-c 2.7.  I am having a problem
validating XML against a given DTD (a string).

I am using SAX2XMLReader and using loadGrammar(...) to
load the DTD. My code is something like this:

    SAX2XMLReader* parser =
XMLReaderFactory::createXMLReader();
    parser->setFeature(XMLUni::fgSAX2CoreValidation,
m_bValidate);
    parser->setFeature(XMLUni::fgXercesDynamic, true);
   
parser->setFeature(XMLUni::fgXercesCacheGrammarFromParse,
true);

    parser->loagGrammar(DTDInputSource,
Grammar::DTDGrammarType);
    
    parser->setErrorHandler(errorHandler);
    parser->setContentHandler(contentHandler);

    parser->parse(XMLinputsource);

I noticed that the validation is not happening,
invalid xml gets parsed without problem. However, if I
don't use loadGrammar(...), instead, I embedded the
dtd content into XML input using <!DOCTYPE ... ]>,
then the validation happens correctly. 

Do I need to do some special settings? any problem
with loadGrammar(...)? 

Thanks much.
Frank
