Ok I think I have pieced together a solution but would appreciate one last ( hopefully ) piece of wisdom.

the host section of the log can look like any of the following examples

blah blah H=(10.21.32.43) [192.168.8.34] blah
blah blah H=([10.21.32.43]) [192.168.8.34] blah
blah blah H=mailsrvr.mail.com [192.168.8.34] blah

[download]

The data I want to assign is the number in the square brackets i.e. 192.168.8.34

How would I go about pattern matching to extract this i.e ip address in square brackets after space following initial text following H=

Many Thanks, Steve
