Using regex to match a sting in a replace function

Damien_Rosario thanks for the input.  After literally wasting half a day trying to get regex to work i found one entry in Google that appears to indicate regex is not supported natively.  Can't imagine why its not but there you go.

Thanks for your suggestion I was able to get it to work within Flow using splits and concatenates its just 8 steps long which seem crazy when it could be done in one replace if only regex was supported.
