How to use use Regular Expression (RegEx) within Azure logic app

Question

I want to verify a value in my azure logic app which follows a pattern which can be identified by Regular Expressions.

My Value is KUL-M-X-Y, here KUL is fixed value but value of M can be "KG", "TON" etc., also Value of X and Y can be numeric.

I searched for RegEx related expression in Logic apps but didn't find any.

Can any one suggest possible way to work with this?

You can use inline code with Azure Logic Apps to handle regular expressions. I ran through the example and modified it to use the following regular expression:

/([K][U][L]-[a-zA-Z]{2,3}-\d\d)/g

You can then use a normal Condition step to check for existence of the results (if a match) or null if not:

Here is the code in the inline code step, for reference:

var reg = /([K][U][L]-[a-zA-Z]{2,3}-\d\d)/g;
var email = workflowContext.trigger.outputs.body.body;
return email.match(reg);
