How do I extract a string using regexp?

I need to find a string somewhere on a page and then store the matching string to a variable so I can echo it to the log, branch on it, etc.

The page can have a variable number of lines, but somewhere on one of the lines is a string like " price code nnnn " where n is a digit. How do I get that into a variable?


The regexp would be something like:

/(^.*)(\sprice code\s\d{4}\s)([\s\S]*)/$2/m

In Perl I would easily grab subgroup $2, but I cant seem to replicate this in the IDE (natively or by calling javascript).

Any help?



Thanks,
Eric
