[scew-users] scew_element_by_name error..

[mach]

Hello Dear;

I am testing the api of scew-1.1.2 as below using 
example/scew_print/scew_print.c.
The example works fine without appended part.
But scew_print abort with a message like below when compiled with appeded part.

lt-scew_print: scew_print.c:189: main: Assertion `element != ((void *)0)' 
failed.
Aborted

Could you let me know what is wrong or missed.

#inlcude <assert.h>
...
... 
...
      /* Frees the SCEW parser and reader. */
      scew_reader_free (reader);
      scew_parser_free (parser);
      return EXIT_FAILURE;
    }   

  // ---------------------------------------------  appended from here
  {
          scew_element *element = NULL; 
          scew_element *root = NULL; 

          root = scew_tree_root (tree);
          assert(root != NULL);
          element = scew_element_by_name(root, _XT("trt:Profiles"));
          assert(element != NULL);
  }
  // ---------------------------------------------  appended to here

  /* Prints full tree. */
  scew_printf (_XT("\n*** Manual print:\n\n"));
  print_element (scew_tree_root (tree), 0); 


Thanks,

Best regards,

Mach
