Use xmlReadFile and you can pass parser options as the 3rd argument:
m_pXmlDoc = xmlReadFile(szFilename, NULL, XML_PARSE_DTDLOAD | 
XML_PARSE_DTDATTR | XML_PARSE_NOENT | XML_PARSE_HUGE);

Using this you should also be able to remove the use of the global vars 
(xmlLoadExtDtdDefaultValue and xmlSubstituteEntitiesDefault).
