code: function _getTagsInPlatform(pelem, tag, platform, transform) {
      var platformTag = pelem.find('./platform[@name="' + platform + '"]');
      var tags = platformTag ? platformTag.findall(tag) : [];
      if ( typeof transform === 'function' ) {
          tags = tags.map(transform);
      }
      return tags;
  }
docs: Same as _getTags() but only looks inside a platform section.
