Answer 1

If you care about readability, i suggest to just use "split", like so: string.split("from").last.split("to").first or, in your case:

to.split("+").last.split("@").first

use the limit 2 if there are more occurancies of '+' or '@' to only care about the first occurancy: to.split("+",2).last.split("@",2).first
