Re: DOM Validation of XML against a schema

Hello,

You could define an ErrorHandler and then try something like this before 
parsing :

    parser->setErrorHandler(myErrorHandler);
    parser->setValidationScheme(XercesDOMParser::Val_Always);
    parser->setValidationSchemaFullChecking(true);
    parser->setDoNamespaces(true);
    parser->setDoSchema(true);
    parser->setExitOnFirstFatalError(true); // exception si le schema 
n'est pas trouve
    parser->setValidationConstraintFatal(true);
    parser->setIncludeIgnorableWhitespace(false);
    parser->setCreateCommentNodes(false);

    parser->setExternalSchemaLocation( ... );

We use XercesDomParser this way and get the parsing errors as exceptions.

Regards,
