Hello, I am attempting to parse some data that looks like the following: 
Users of some feature

   user1
   user2
   user3
   ...

Users of some other feature

   user1
   user2
   user3
   ...

Users of yet another feature

...

What I am trying to figure out is how to count the number of users utilizing each feature. I have been playing around with the .. and ... operators but have not been successful.
Thanks for any help you can give
