ThankYou for your contribution

We already have a RegexUtil Scriptinclude in our repository RegexUtils

Closing this for now. Once you make additional changes, feel free to re-open this Pull Request or create a new one.

Hi @rohi-v

Trying to understand your comment, so I need to add function under script include mentioned? As regular expression has its own folder so placed this one there. Also util is not having this check.

Hi @vhudlikar

We already have regexutils available with the same underlying logic. The only difference in this case is the regex expression being used, which can be provided as an input to the existing utility method.

Therefore, this appears to be just an example rather than a new enhancement.
