OT: PERL Question

2nd reply, since GigaNews doesn't seem to like alt.binaries.

Note that I do all my Perl programming with

open. I'm mostly not a Perl programmer!

I know you can search for groups of three digits, and probably groups of three digits bound by non-digits (I'm pretty sure you can search on "\D(\d \d\d)\D", but I know that "[^0-9]([0-9][0-9][0-9])[^0-9]" will work -- there's probably a way to say "repeat three times" but I don't know it).

I'd identify groups of three, then parse them for value and test with an if statement. I'm pretty sure that making regular expressions to test by value in the text would be exceptionally tedious.

Independent of language, I'm guessing the best answer will be regular expressions. Most all languages support regex. Sadly I don't know them, so I can't compose one offhand.

Hmm, just asked a friend, says a regex would be obscene. Nevermind.

For a heavy weight solution, I wonder if it could be fed into Google Docs and queried with Google search tools? That supports a range search.

I'm no expert on regex, but I think this works

19[2-9]|2[0-1][0-9]|22[0-2]

Thanks for the nudge, Lasse. I think something like that will work. ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

Tested, it does work, Thanks! ...Jim Thompson

It's just a regex thing- first hit on Google

Assuming between is inclusive, this, I think:

\D(19[2-9]|2[01][0-9]|22[012])\D

umop apisdn

a digit is denoted by \d, so \D(\d{3})\D ; checking that by running in Perl debugger

perl -de 1

main::(-e:1): 1 DB $_= "abc123def"

DB ($a)=/\D(\d{3})\D/

DB p $a

123

So then you'd check if this 3-digit number is in the range

p (192 < $a ) && ($a < 222)

Lasse's suggestion helped me sort it out, but your post reminded me that I have a copy of "Regex Buddy" which does exactly what your link does... I just need to install it on this machine. ...Jim Thompson
