For getting this result, I would approach it differently. I would define a hash, %tags, which is initially empty. Whenever you encounter a tag, say AUTHOR, with some content, say 'author1', you have have two cases:
  1. If AUTHOR does not exist yet in your hash, create a new entry with AUTHOR as a key, and 'author1' as a value.
  2. If AUTHOR already exists in your hash, just append to the existing string your new value (separated by a space).
