  Use the existing code from xmllint.c which does exactly this when passed
the --memory and --dtdvalid flags !

Direct cut and paste from the code:
-----------------
        doc = xmlParseMemory((char *) base, info.st_size);
-----------------

-----------------
        xmlDtdPtr dtd;

        dtd = xmlParseDTD(NULL, (const xmlChar *)dtdvalid);
        if (dtd == NULL) {
            xmlGenericError(xmlGenericErrorContext,
                    "Could not parse DTD %s\n", dtdvalid);
            progresult = 2;
        } else {
            xmlValidCtxt cvp;
            if ((timing) && (!repeat)) {
                gettimeofday(&begin, NULL);
            }
            cvp.userData = (void *) stderr;                                                 cvp.error    = 
(xmlValidityErrorFunc) fprintf;                                  cvp.warning  = (xmlValidityWarningFunc) 
fprintf;
            if (!xmlValidateDtd(&cvp, doc, dtd)) {
                xmlGenericError(xmlGenericErrorContext,
                        "Document %s does not validate against %s\n",
                        filename, dtdvalid);
                progresult = 3;
            }
       }
