isolate a number in a text

[Regis MAHOUKOU]

I want to isolate a number from a text for automation.
I tried match, split and replace functions but not working.

Someone can help ?

Hi @Regis MAHOUKOU and Welcome to Atlassian Community!

It's easy to do with a Regex expression.

For example, I have a description with the current value:

And I have the following automation:

After execution, I'll get:

I recommend you this site Pattern class and this article rules documentation around regular expressions

Thank so much @Sergei Troshin 

I've successfully tested your example.

The issue I have : "Effort" field contains a textd "3 Medium" that need to be isolated.

The functions replaceAll, split or match are not working on this.

Hi @Regis MAHOUKOU 

1) Do you have a text field named "Effort"? Or what is the field type?
2) Do you need to extract "3" from the value "3 Medium"?

[Regis MAHOUKOU]

Yep Effort is text field conatining this "3 Medium". I want to catch the number 3 so I can use it for calculation.

Hi @Regis MAHOUKOU again!

It works:

{{#=}}{{issue.customfield_10058.replaceAll("[a-zA-Z]","")}} * 2{{/}}

I successfully removed all letters, multiplied the result, and put it into a Number Field.

Hi @Richard Cho - ServiceRocket 

I am blocked on with the Split function

Is the Regex functions activated by default for Automation in JIRA ?
