I have a string in this form:

sub = 13433

cf-ipcountry = US

mail = abc.test@gmail.com

ct-remote-user = testaccount

elevatedsession = N

iss = www.google.com

user-agent = Apache-HttpClient/4.5.8 (Java/1.8.0_322)

I want to extracr iss fields value

I tried this but did not work

| rex max_match=0 field=_raw "\/sub \/user-agent \/(?<temp>.*)"

Is this the exact string you have in your event? If so, try

| rex "iss = (?<iss>\S+)"
