Hi Jason,

If you actually look at the syntax of what you are parsing, it is very 
simple.

My recommendation would be to write a recursive decent parser for your 
files.

That way will be easier to write, much easier to modify and almost 
certainly faster that a RE solution - and it can easily give you all the 
information in the file thus future proofing it.
