XML :

I get the error when reading a file T x; try{ FileStorage f(fname, FileStorage::READ);

      if (!f.isOpened())      {          cout << "Could not open the configuration file: \"" << endl;        }      f["name"] >> x;      FileStorage ff = f;      f.release(); return x;  }  catch (std::exception const& e)  {      std::cout << "Message: " << e.what() << "\n";        std::cout << "Type:    " << typeid(e).name() << "\n";  }    

} `
