Support for Regex in Flow

IsMatch, Match, and MatchAll functions are already supported in PowerApps. Why can't they also be supported in Flow?  Here's a simple scenario that is very difficult to do without Regex support.

 

I'm starting an Approval Flow to be sent to a user's manager.  I check a user's manager's mailbox to see if an Out of Office message is set.  Such a message will normally include the email address for another person to contact.  I want to extract that email and use it to escalate the approval to that other person.  I can easily extract that email address using Match().  Doing it without Regex is almost impossible.

 

Why are these functions supported in PowerApps but not in Flow?

one of the best, and certainly most underrated feature requests out there.  I wouldn't have my current issue if Regex was supported.

Currently not using flow because of this limitation.

I've written up a method of performing Regular expression matches and substitutions in Power Automate, check it out here:

How to use Regex in Power Automate 

This method uses no external connectors and does not require a premium licenses but does give you full Regex support.

Hope this is useful to everyone waiting patiently for this feature to be a standard part of Power Automate.

Still waiting for RegEx in Flow for years. It would such a great improvement and prevent tons of cascades of nodes and functions calls / expressions.
