Trying to create a custom Field Extraction

[scout29]

I am trying to write a regex to extract a field called "registrar" from some data like i have below. Can you please help how i could write this regex to be used in a rex command to extract the field? Below are three example events:


Registry Date: 2025-10-08T15:18:58Z   Registrar: ABC Holdings, Inc.   Registrar ID: 291  Server Name: AD12

Registry Date: 2025-11-08T15:11:58Z   Registrar: OneTeam, Inc.   Registrar ID: 235  Server Name: AD17

Registry Date: 2025-12-08T15:10:58Z   Registrar: appit.com, LLC   Registrar ID: 257  Server Name: AD14

I need the regex to use to extract the field called "registrar"  which in the above example would have the following three value matches:  

ABC Holdings, Inc. 

OneTeam, Inc

appit.com, LLC

Assuming the fields are always in the same order, this should do it.

| rex "Registrar: (?<registrar>.*?) Registar ID"

Try adding this to your search

| rex field=_raw "Registrar ID: (?<registrar_id>\S+)" 

Update: I misread your post, standby for an updated search to include all three field extraction - unless someone else beat me to it. You can also use the "Extract New Fields" or "Event Actions" option when you run your search.

i am looking for the field registrar to be extracted. There are three spaces after the registrar string - but i cant seem to write my regex to capture the full registrar name up to the three spaces. I am using this but not getting the full string extracted 

\sRegistrar:\s(?<registrar>\w+\s\w+)

Try this - I'm not the best at regex and someone else may come along and provide a more efficient one.

Registrar: (?<registrar>.+[^\s]).+Registrar ID
