Help with Regex

dru145 has asked for the wisdom of the Perl Monks concerning the following question:

Monks,

I would be most gratefull if a monk can help me out so that I can stop banging my head ask my desk (it's starting to hurt).
I have the username out of these two patterns:

1. Sep 20 19:05:06 nts-sa-nam NA(shiva-NA): phen.2048: This Certificat
+e has been renewed.<br><br>
2. Sep 21 04:40:46 nts-sa-nam NA(shiva-NA): [jlee] Certificate name 'h
+jingi.512' has been revoked.
[download]

Here is the regex that I have so far: m/(\w+\.(2048|512)).*renewed|revoked/ which matches the username in the first entry but not the second.

Any suggestions?

`m/(\w+\.(2048\|512)).renewed\|revoked/` [download] is similar to `m/(\w+\.(2048\|512)).renewed/ or m/revoked/` [download] because of the precedence of the vertical bar. You want (I think): `m/(\w+\.(2048\|512)).*(renewed\|revoked)/` [download] -- Randal L. Schwartz, Perl hacker	[reply] [d/l] [select]

you need parens around the last bit... `m/(\w+\.(2048\|512)).*(renewed\|revoked)/` [download] otherwise I belive you are matching just the word revoked in a revoked line... - Ant - Some of my best work - Fish Dinner	[reply] [d/l]

Thanks guys, That was it! I didn't even think to look at that part of the pattern. -Dru (Another satisfied monk)	[reply]
