Having read the rest of your conversation with Jonathan, I'm going to
suggest a related book that I think may help you approach this from a
different angle: _Mastering Regular Expressions_ by Jeffrey Friedl.  (I
haven't gone through SICP myself, so I can't be sure that it's relevant,
but it covers the topic of transforming search criteria into executable
statements -- and it will almost certainly be useful to you even if it's
not relevant to your current problem.)

definition, not smart enough to debug it."  --Brian W. Kernighan
