How to validate a xml file that refers to an xsd file using sax parser provided by Xerces-C++ ?

Hello,

I try without success to validate a xml file that refers to an xsd file using sax parser provided by Xerces-C++ ?

The following code does not work ( parsing a not well-formed xml will report error as expected, but an invalid xml - with respect to xsd - will not report error ) :
XMLPlatformUtils::Initialize ();
SAXParser * pParser = new SAXParser ();
if ( pParser )
{
  pParser -> setDoSchema ( true );
  pParser -> setLoadSchema ( true );
  pParser -> setExternalNoNamespaceSchemaLocation ( xsdFile.c_str () );
  pParser -> setValidationScheme ( SAXParser::Val_Auto );
  pParser -> setValidationSchemaFullChecking ( true );
  pParser -> setValidationConstraintFatal ( true );
      
  SaxParserHandler handler; // SaxParserHandler derives from HandlerBase
  pParser -> setDocumentHandler ( &handler );
  pParser -> setErrorHandler ( &handler );
  pParser -> parse ( xmlFile.c_str () );
      
  delete pParser; pParser = NULL;
}
XMLPlatformUtils::Terminate ();

I want the parse to stop if the xml is not compliant with the xsd. Bonus if I don't have to handle "by hand" the xsd ( setExternalNoNamespaceSchemaLocation ) : is there a way to tell the parser to validate automatically the xml with xsd in case xml refers to a xsd ?

Can somebody help me on that ?

Hello!

SAX2Counter.exe which is included in XERCES already performs a check against an xsd. Maybe this is a good starting point.

Sincerely,
Daniel
