Thanks for your prompt response.

I am using xmlParseDTD as described in your mail. My
code reads as follows and the behaviour is as
described in previous mail. I am unable to figure my
problem:


if ((dtd = xmlParseDTD(NULL, (const xmlChar *)
             dtdvalid.c_str())) == NULL)
{
    printf ("Could not parse DTD\n") ;
}
else
{
    xmlValidCtxt cvp;
    cvp.userData = (void *) stderr;
    cvp.error    = (xmlValidityErrorFunc) fprintf;
    cvp.warning  = (xmlValidityWarningFunc) fprintf;
    if (!xmlValidateDtd(&cvp, _doc, dtd))
    {
	printf ("XML contents does not validate
                  against DTD\n");
    }
}
