Re^3: Regex, extracting stuff from the middle of a line

Messed up my question on the regex thing. Here is some example lines:

Created by a.buncha.stuff.I.dont.want\GeorgeO at the parker inn
date : 06-Aug-06:22.34.01 buncahstuffIdon'twant
Created by a.buncha.stuff.I.dont.want\7of9 at the parker inn
date : 06-Jan-06:22.34.01 buncahstuffIdon'twant

Please get me:
GeorgeO
06-Aug-06:22.34.01
7of9
06-Jan-06:22.34.01

Your requirements are very vague. You didn't specify which components are constant and which are not. I assumed "\" and "date : " are constant. You didn't specify of which chars the variable parts could be made. I assumed what is represented by "GeorgeO" could contain spaces (which required specifying " at the parker inn"), You didn't specufy from where the lines came. I assumed a file handle. You didn't specify what to do with the extracted values. I print them. `while (<$fh>) { print("$1\n") if /\\(.*?) at the parker inn$/ or /^date : (\S+)/; }` [download]	[reply] [d/l]

And your code that's not working looks like . . .? Show some effort of your own before submitting work requests. See How (Not) To Ask A Question. Update: Oop, didn't realize this was a followup to a prior question. Probably because it was exceedingly vague and offered no context or indication otherwise, so the how-not-to-ask-ing's still relevant.	[reply]

You should escape the special '\' symbol: `m\|\\(\w+)\| and print $1, "\n";` [download] For the date/time: `m\|:\s+(\S+)\| and print $1, "\n";` [download] See perlre	[reply] [d/l] [select]

While ikegami said pretty much everything I wanted to say, I suggest that if you can come up with a set of explicit rules for what you want removed or, conversely, kept, the code will be easy (perhaps not the most elegant possible). emc Outside of a dog, a book is man's best friend.
