The .* lets your match cross over section boundaries.
$stayinsection acts just like .* but will not allow crossing over your section boundary of "\n\n"
Just a slightly advanced regex trick :)

use strict;
use warnings;

my $stayinsection = qr/(?:(?!\n\n).)*/s;

$_ = do { local $/; <DATA> };

print "<$1> <$2>\n" while
