How can I extract the nth occurrence of a match in a Perl regex?

Question

Is it possible to extract the n^th match in a string of single-quoted words?

use strict;
use warnings;

my $string1 = \"\'I want to\' \'ex         


        

Answer 1

The match-g operator evaluated in an array context yields an array of matches. Therefore:

@matches = $string =~ /'(.*?)'/g;
$matches[$index-1];

is one way to get what you want.
