Re: Regexp string concat

First - doesn't BioPerl have a few functions that will do this?

As for code ... you still don't have all the requirements laid out yet. Specifically:

Do the matches have to be in the order specified? For example, what should @new_query contain if $string = 'EICHENLEBAUMSCHU'?
What happens if something in @query isn't there? For example, $string = 'XXX'.
What happens if there is more than one match? For example, $string = 'EICBAUMEIC'.
What happens if something isn't there and there's two matches on something else?
What happens if one element in @query fits into another element? For example, @query = qw( BAUM AU ).
What happens if there are two possible solutions? For example, $string = 'BAABAB' and @query = qw( AA BA ).

I'm sure there are other possibilities that I didn't think of in the first five minutes of looking at the problem. Remember - if you can't explain the problem to a teddy bear, you can't explain the problem to a computer.

I shouldn't have to say this, but any code, unless otherwise stated, is untested

Heh. Your requirements seemingly contract each other. Specifically, you state that @new_query = @query if a value in @query isn't matched. However, you say that if something isn't matched and something else is matched twice, remove the double. But, you say that there can never be a double match. In other words, it doesn't sound like you can explain the requirements to a teddybear. I would spend some time with pencil and paper before going much further. Then, when you have pencil and paper down, convert those into test cases before writing any code. ------ We are the carpenters and bricklayers of the Information Age.
