A more generalized way to handle such requirements is with a Finite-State Machine (FSM) approach. The algorithms consider, not only the current line of input, but the $state that the FSM is “in” at the time, where the current value of $state is determined by recent history of lines seen.
Sounds cool. I found a lot of interesting hits using Super Search: All these glowing endorsements have got me excited, yet I couldn't find any sample code in any of these nodes. So I was wondering if you could post some of the excellent FSM code you've implemented over the years? It would really help me to better understand FSMs.
