Re: Where did the regexp fail?

Thanks Chris, Peter, Drew and Tim for your helpfullness. I appreciate 
it. But my struggles with regexps and all the parenthesis are very easy 
today since I always use rx for complicated regexps.

My struggle with trying to express what I am looking for is however not 
at all finished ;-)

I wanted some kind of simple parser for data in a buffer, but I realize 
now that I have to write a small small parser to be able to give the 
feedback I want to the user.
