in reply to Re: matching numeric range
in thread matching numeric range

I'm liking this. One question on this. Is there a simple way (one line regex substitution for example) to get from B10-15 to B1[0-5], or B120-125 to B12[0-5]? Actually, as I think about it, I may need to apply some logic to handle B18-24. Can you think of a good way to handle this one?

    the B10-15 example is easy: B1[0-5] (character class), as is B120-125 (B12[0-5]). As you say, logic spanning B18-24 is more difficult; that's why I broke it into 2 regexs in my post above. It was easier to match B1[8-9] or B2[0-4] than to try some regex-fu. You may be more adept with regexes than I am.

    update: escape out [ ] so they're visible.
