Hi,

I'm trying to load a grammar to be used with a DOMBuilder. The problem is that 
when I call 'parser->loadGrammar(...)' an unknown exception is thrown. My 
debugger prints:

First-chance exception in myXMLApp.exe (XERCES-C_2_3_0.DLL): 0xC0000005: Access 
Violation.

I've tried numerous DTD's, and even the DTD 'personal.dtd' that comes with the 
download fails in the same matter.

This is what I do:

  static const XMLCh gLS[] = { chLatin_L, chLatin_S, chNull };
  DOMImplementation* impl = 
    DOMImplementationRegistry::getDOMImplementation(gLS);
  DOMBuilder* parser = ((DOMImplementationLS*)impl)->
    createDOMBuilder(DOMImplementationLS::MODE_SYNCHRONOUS,NULL);

  if(parser->canSetFeature(XMLUni::fgDOMNamespaces, true))
    parser->setFeature(XMLUni::fgDOMNamespaces, true);

  if(parser->canSetFeature(XMLUni::fgXercesSchema, true))
    parser->setFeature(XMLUni::fgXercesSchema, true);

  if(parser->canSetFeature(XMLUni::fgXercesSchemaFullChecking, true))
    parser->setFeature(XMLUni::fgXercesSchemaFullChecking, true);

  if(parser->canSetFeature(XMLUni::fgDOMValidation, true))
    parser->setFeature(XMLUni::fgDOMValidation, true);

  if(parser->canSetFeature(XMLUni::fgXercesLoadExternalDTD, true))
    parser->setFeature(XMLUni::fgXercesLoadExternalDTD, true);

  Grammar* gram;
  try {
    gram = parser->loadGrammar("$THE_PATH/personal.dtd",
      Grammar::DTDGrammarType,true);
  }
  catch(const XMLException& problemExc){
    char* message = XMLString::transcode(problemExc.getMessage());
    XMLString::release(&message);
  }
  catch(const DOMException& problemExc)
  {
    char* message = XMLString::transcode(problemExc.msg);
    XMLString::release(&message);
  }
  catch(const SAXException& problemExc)
  {
    char* message = XMLString::transcode(problemExc.getMessage());
    XMLString::release(&message);
  }
  catch(...)
  {
    // This is where I end up!
    printf("Unknown Exception\n");
  }

I would really appreciate an answer. 

Thanks, 
Patric.
