in reply to Recommendations for breaking up string?

Fun problem! Here is my take. The bulk of the work is done via a regex, and since the target delimiters appear first, reversing the string makes the matching easier. I do not recommend this solution for production, but rather as a learning experience. It assumes the roles are uppercase characters between 2 and 4 chars in length.

use strict; use warnings; my $str = scalar reverse "QB Carson Palmer RB Chris Ivory RB Eddie Lac +y WR A.J. Green WR John Brown WR Davante Adams TE Martellus Bennett F +LEX Jeremy Hill DST Panthers"; for ($str =~ /(.*?[A-Z][A-Z][A-Z]?[A-Z]?)/g) { $_ = scalar reverse $_; chomp( my ($role,@name) = split ); print "$role -> @name\n"; } __DATA__ DST -> Panthers FLEX -> Jeremy Hill TE -> Martellus Bennett WR -> Davante Adams WR -> John Brown WR -> A.J. Green RB -> Eddie Lacy RB -> Chris Ivory QB -> Carson Palmer
