Converting Brackets

I have Titles that have <<< and >>> in the Title and I need to change these to Standard Brackets.

Is there a way to change single of multiple instances of a < to an Opening Bracket and conversly changing Single or Multiple instances of > to a single Closing Bracket.

Thanks for your help

I guess that you want to replace '<<<<' with '(' and the same with closing brackets.
For this create 2 actions of the type "Replace with regular expression
Search string: <+
Replace string: (

and the other one with
Search string: >+
Replace string: )
