Hi @SamLima,

There are various regular expression testers online that you can use for testing. You just need an example of the data you're going to run the tests against. Here's one that I've used in the past:

http://regexstorm.net/tester

There's also a Reference page on that site that shows information about the various flags, etc that can be used in RegEx's.

Cheers,

Hi Sam,

There are two steps to it basically:

First step is first building regular expression using some online resource:

You can use a lot of resources to test the Regular expressions that you create using the following resources: Regex Tester , Regex101etc

Second step is to actually implement it from Blue Prism:

Once you have a regular expression in place, next step is to download and import the latest asset from Digital Exchange: Utility - Strings

Here, you can find a lot of useful actions that you can use to get various operations done using regular expressions like you can validate if a pattern of string exists or not as per your regular expression, you can also replace any string if you want if it matches your regular expression, you can also extract a set or subset of strings based on the pattern described by your regular expression from a entire text data.

I would suggest start using each of the action and go through the initial values defined in each of the actions in Object Studio to get a better understanding of how they work. Let me know in case you face any issues while understanding any one of these actions.
