If I understand correctly (which I'm sure I don't fully), why not set some flag in your handler if the filter name your looking for exists (or save the filter names in a hash?), and then warn or die after the parse if the filter name wasn't there? Or you could warn or die inside the Filter handler if the Name you're looking for isn't there.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
