c++ - Template auto-generated code, not a type -

i'm attempting generate class can read type of serialized xsd/xml code. since have 1000 different data defintions, love make xmlloader class generic.

however, in auto-generated serialized code, way obtain pointer in-memory data difficult me grasp.

the code:

template <class xmltype> class xmlloader { public:      xmlloader(const std::string &filename, const std::string &xsd) :     filename(filename),     xsd(xsd) {         try {             this->initialize();         } catch (const xml_schema::exception &e) {             error("unable parse [%s], aborting\n", filename.c_str());         } catch (const std::invalid_argument &e) {             error("unable locate [%s], aborting\n",                     std::string(component::getjarssxsddirectory() + xsd).c_str());         }     }      std::auto_ptr<xmltype> xmlinstance;  private:      void initialize() {          std::string schema = component::getjarssxsddirectory() + xsd;         if (!application::validatepath(schema)) {             throw std::invalid_argument("xsd cannot found");         }          xml_schema::properties props;         props.no_namespace_schema_location(schema);         xmlinstance = std::auto_ptr<xmltype > (xmltype_(filename, 0, props));     }      std::string filename;     std::string xsd; }; 

the problem lies line: xmlinstance = std::auto_ptr<xmltype > (xmltype_(filename, 0, props));

if hand, like:

xmlinstance = std::auto_ptr<xmltype>(xmltype_(filename, 0, props)); 

notice _ function on xmltype.

when try template this, compiler states xmltype_ isn't type, nor included in argument template.

since xmltype_ isn't type, it's function generated xsd serializer, how can pass through template? i've never encountered before.

any ideas?
