Is it possible to match on nth instance of a marked subexpression? For
example, with the string:
"hello _world_ !!!"
I would like to extract the world "world". The closest I can get to is
using the regex expression:
This gives me two subexpression matches
I can't seem to be able to select the 2nd subexpression using
"_(.*)_\2", I guess it's not supported?
