Automation Using RegEX

Guy Slade

What I am trying to do is grab the labels from an issue and then use regex to look for a pattern and if it is there assign the sting to a variable. As you can see below I am using a Restful call to grab an issue. I have:

parentLabels = {{webhookResponse.body.fields.labels}}

filterByRegEx = {{parentLabels.match("PI-[0-9]+-[0-9]+")}}

and as you can see below I write the values of these two vars out to the log. 

The parentLabels looks good but there is nothing in filterByRegEx. I know I have a string in parentLabels as I can successfully substring out what I am looking for when I hardcode the start and end. ( I am looking for "PI-3-24")

What dumb newbie mistake have I made?

Hi @Guy Slade -- Welcome to the Atlassian Community!

I see two things to adjust in your rule:

First, a created variable is plain text, and when the labels are added, by default the list flattens out to a comma-and-space separated values list.  To feed them into match(), they must be split back apart with split(", ") into a list.

Next, I believe the match() expression will need a group for this case.

Putting those together:

{{parentLabels.split(", ").match("(PI-[0-9]+-[0-9]+)")}}

Kind regards,
Bill
