Hello Kalicharan,
You can use the Dynamic Expression Assigner Step for a dynamic regex. Please, see Tutorial 06.07 for an example of how to use the Step.
Also, keep in mind that matches() requires a Boolean column. So you would have to use ToString before matches for the expression to work - ‘toString(matches())’.
