I need to select fields from a log who are between two [ ]
Event 1: Some data... [ AAA ]
Event 2: Some data... [aa - DD ]
I need those fields
AAA
aa - DD
DD
How to do that? I'm using this regular expression (?P
[AAA
[aa
and this is wrong i don't need the first character [ and need to get all the data between [ ]
Once you figure out your starting point, you can use (?P
You can do something like
\[(?P<fieldname>[^\]]+)\]
This way you will pick up everything between an open bracket ([) and a close bracket (]) as long as it's not a close bracket.
Notice that I have escaped the open bracket and two of my close bracket. This makes the regex use the escaped brackets as a character instead of trying to parse them as part of the regex.
Hope this helps
