There are a large number of ways to solve this problem and the best solutions probably involve recursion to deal with nested directories. However, you haven't asked for such a solution (yet) so here's a solution that uses Perl 5.10 (and later)'s switch statement:

use strict;
use warnings;
use 5.010;

my $lsResults1 = {
    'recursive' => 'no',
    'version'   => '0.20.202.1.1101050227',
    'time'      => '2011-10-26T00:21:06+0000',
    'filter'    => '.*',
    'path'      => '/work/eng/feeds/customer_care',
    'directory' => [
        {
            'owner'      => 'tst_act',
            'group'      => 'eng',
            'permission' => 'drwxr-xr-x',
            'path'       => '/work/eng/feeds/customer_care',
            'accesstime' => '1970-01-01T00:00:00+0000',
            'modified'   => '2011-10-25T23:54:17+0000'
        },
        {
            'owner'      => 'tst_act',
            'group'      => 'eng',
            'permission' => 'drwx------',
            'path'       => '/work/eng/feeds/customer_care/abc',

        },
        {
            'owner'      => 'tst_act',
            'group'      => 'eng',
            'permission' => 'drwx------',
            'path'       => '/work/eng/feeds/customer_care/test',

Notice the use of ref to determine what type of directory entry is being dealt with and the use of keys to work through the hash entries looking or the interesting stuff.

True laziness is hard work
