Regex: exact values of customfield

[felix.weber]

Hi

I have an similar issue to https://community.atlassian.com/t5/Jira-Service-Management/Automation-Customfield-exactly-matches-regular-expression/qaq-p/1827350

My Customfield is a select-list and contains different websites, e.g.:

DomainA - Blog
DomainA - Wiki
DomainB - Blog
DomainB - Extension
DomainC - Website
DomainC - Info

In the condition of my automation I want to make sure that only websites from DomainB has been selected (using "exactly matches regular expression")

the super basic idea was:

(DomainB - Blog|DomainB - Extension)

However this does work only when one of them is selected, so in case both are selected the condition does not work 

meanwhile ended up in

(?i)(DomainB).*

 however if e.g. a website from DomainA or DomainC has been selected the condition is valid is well :( 

maybe I was already close to the solution but I am really struggeling with Atlassian regex

Hi Felix

Maybe you could try the startsWith(String str) from the jira smart values text fields documentation instead if all values are like DomainB as this would potentially be easier then using/struggling with the regex

https://support.atlassian.com/cloud-automation/docs/jira-smart-values-text-fields/

If the regex option is the only way then the regex could potentially be as basic as 

DomainB

 which would match, or more complicated like to match the space and hyphens

DomainB\p{Space}\-\p{Space}

thanks for your idea, however the problem is, its a select-list.

So multiple websites can be selected. Furthermore I also don´t know how many websites are selected.

So can´t use the startsWith(str) 

I don´t want to know if DomainB is somewhere in the selection I need to know the opposite or kind of that ONLY DomainB has been selected and no other domain (without naming all others - because all others are way more)
