  $data = array();

  // Get the XML as a string.
  $manifest_string = file_get_contents($manifest_file);

  // Parse it as an array.

  // The parser returns an array of arrays - skip the first element.
  $manifest = array_shift($manifest);

  // Get the manifest ID, if any.

  // Combine the resources and SCOs.
  $data['scos']['items'] = opigno_scorm_combine_manifest_sco_and_resources($data['scos']['items'], $data['resources']);
