Here are half a dozen ways to get that.

The value of an answer is directly proportional to the care
given in asking the question...

use warnings;
use strict;

$_ = q($string['bababa']='jajaja');

my @matches = /([abj]+)/g;
print "@matches\n"; # only the "good" letters

@matches = /'([^']+)'/g;
print "@matches\n"; # single quoted

@matches = /(\w+a)/g;
print "@matches\n"; # ends with "a"

@matches = /(\w+)'/g;
print "@matches\n"; # ends with "'"

print substr($_, 9, 6), ' ', substr($_, 19, 6), "\n"; # no regexes at all!

tr/=/ /; # this one's *not* a regex
s/[^abj ]+//g; # but part of this one is
print "$_\n";
