   I can't understand what you wrote, sorry.
you can parse a DTD with 

  xmlDtdPtr       xmlParseDTD             (const xmlChar *ExternalID,
                                           const xmlChar *SystemID);

   You should not have to write you own DTd parser libxml has one...

  xmlElementPtr   xmlGetDtdElementDesc    (xmlDtdPtr dtd,
                                           const xmlChar *name);

  right it's not allowed, read the spec.
