I built something similar (not quite as pretty) for parsing SWF tags in Ruby: http://github.com/daeken/Arienette/blob/master/swfTags.rb http://github.com/daeken/Arienette/blob/master/swfTags.rb Also in that repo is the beginning of a Ruby compiler for Flash, as part of an implementation that was intended to compile Flash apps to native iPhone apps, before Adobe announced they were doing the same thing.
