Regular expression with a small bug

I have this string 

hey {Bobby|Apple|Peter}, nice to meet you {David}

and this regex: 

(\{(\w+)(\|(\w+))*)\}

the answer: 

Bobby
Peter
David

However, it's not getting "Apple", how can I fix this to get it as well?

Thanks!

Repetition does not work for groups. Instead, try to iteratively use find on the string. Probably best to first filter out {Bobby|Apple|Peter}, get the names from that, then find {David} and get the names from that. So that would be two finds, if you keep using regular expressions. Or one find, then a split on | from the result.

Regexp for the find: \{(\w+(?:\|\w+)*)\}, then use group 1 (everything within the braces) and split the result.

Can you show the entire, minimal code that reproduces this problem? It's possible the problem is with how you're iterating through the captured groups.
