All,

I'm needing a little help parsing a log file using Regex. Here is an
example line from the log.

[2010-05-21 02:42:15,307] [WARN,CommandHandler] Duplicate entry

I want to simply break the line into the following chunks:

[2010-05-21 02:42:15,307]
[WARN,CommandHandler]
Duplicate entry

I've tried the following Regex is some success:
\[[^\]]*\]
(?<DateTime>\[[^\]]*\]) (?<Message>.*)

I've already spent quite a bit of time on my own trying to figure it
out. Thanks for any help.

I am not exactly sure what the problem is. The regular expression seems
to work fine, just that DateTime isn't at the right place. If you want
to replace the text with regex to break those onto their own lines,
can't you just replace it all with
${DateTime}\n${WhatThisIs}\n${Message}
?
And you need to use proper line breaks, of course (\n, \r or \r\n).

After reading your post again, it seems like what you want to do is this:

^(?<DateTime>\[[^\]]*\]) (?<PleaseNameIt>\[[^\]]*\]) (?<Message>.*)$

I didn't really change much and the result is this:

DateTime: [2010-05-21 02:42:15,307]
PleaseNameIt: [WARN,CommandHandler]
Message: Duplicate entry
 
Jackie,
