Allow to remove "Taxonomy Vocabulary" from urls

Hello,
I was tried to remove "Taxonomy Vocabulary" from urls, but with no success.
I was found out below code in file "url_processor_pretty_paths.inc", where I was add this comment
/*. $segment['alias'] . '/'*/ ....with this, I was remove vocabulary from urls, but can't be use because after that links don't have affect to contents.

How I could remove it regularly or what next I should do?
Thanks.

    // Add all path segments.
    foreach ($segments as $key => $segment) {
      $this->encodePathSegment($segment, $segment['facet']);
      $path .=  '/' /*. $segment['alias'] . '/'*/ . $segment['value'];
    }
