grouping

Hi ,

I spent lot time figuring out a simple regex to return a group (only 1st group).

So the string can be - "No purchase required" or "Purchase of $50.00 worth groceries is required."

I am trying to write a regex which can parse "No" or "50" based on the given string.

This is what I have written.

(?:(No) monthly maintenance|Purchase of \$([\d\.]+ worth groceries)

This works fine but I want my output as 1st group/group 1 only.
