Dear Monks,

I am trying to learn how to dereference hashref/arrayrefs. So far I have managed to get my test results I want, but having to write (2) different scripts for it.
They are basically the same except for the iteration of the values. I need some help constructing a condition to print the keys I need.

I have a couple of data structures (see below) which is from an xml file and is handled using XML::Simple using ForceArray =>1.

Here is the data structure from dumper, I am working with:

    $VAR1 = {
              '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_car
+e',
                               'accesstime' => '1970-01-01T00:00:00+00
+00',
                               'modified' => '2011-10-25T23:54:17+0000
+'
                             },
                             {
                               'owner' => 'tst_act',
                               'group' => 'eng',
                               'permission' => 'drwx------',
                               'path' => '/work/eng/feeds/customer_car
+e/abc',
                               'accesstime' => '1970-01-01T00:00:00+00
+00',
                               'modified' => '2011-10-25T17:12:56+0000
+'
                             },
                             {
                               'owner' => 'tst_act',
                               'group' => 'eng',
                               'permission' => 'drwx------',
                               'path' => '/work/eng/feeds/customer_car
+e/def',
                               'accesstime' => '1970-01-01T00:00:00+00
+00',
                               'modified' => '2011-10-25T21:05:50+0000
+'
                             },
                             {
                               'owner' => 'tst_act',
                               'group' => 'eng',
                               'permission' => 'drwx------',
                               'path' => '/work/eng/feeds/customer_car
+e/test',
                               'accesstime' => '1970-01-01T00:00:00+00
+00',
                               'modified' => '2011-10-25T21:28:14+0000
+'
                             }
                           ],
              'exclude' => ''
            };
[download]

Here is the code part to extract the directories:

my $lsResults = $cmd->ls("$chkdir"); #$chkdir = "/work/eng/feeds/custo
+mer_care"
#print Dumper($lsResults);
for my $dirnm ( @{$lsResults->{directory}} ) {
    print "Directory:  " . $dirnm->{path} . "\n";
}
[download]

Results:

Directory:  /work/eng/feeds/customer_care
Directory:  /work/eng/feeds/customer_care/abc
Directory:  /work/eng/feeds/customer_care/def
Directory:  /work/eng/feeds/customer_care/test
[download]

The results are fine, until I list the sub-directory that happens to have files: $chdkir="/work/eng/feeds/customer_care/test"

Which in the case the test directory has files and size information that I want to list, but can't due to this message:

Not an ARRAY reference at ./tst.pl

Here is the data dump with that new directory, that shows a file:

    $VAR1 = {
              'recursive' => 'no',
              'version' => '0.20.202.1.1101050227',
              'time' => '2011-10-26T00:30:02+0000',
              'filter' => '.*',
              'file' => {
                        'owner' => 'tst_act',
                        'replication' => '3',
                        'blocksize' => '134217728',
                        'permission' => '-rw-------',
                        'path' => '/work/eng/feeds/customer_care/test/
+q_data_20111023.dat',
                        'modified' => '2011-10-26T00:29:46+0000',
                        'size' => '379085',
                        'group' => 'eng',
                        'accesstime' => '2011-10-26T00:29:46+0000'
                      },
              'path' => '/work/eng/feeds/customer_care/test',
              'directory' => {
                             'owner' => 'tst_act',
                             'group' => 'eng',
                             'permission' => 'drwx------',
                             'path' => '/work/eng/feeds/customer_care/
+test',
                             'accesstime' => '1970-01-01T00:00:00+0000
+',
                             'modified' => '2011-10-26T00:29:46+0000'
                           },
              'exclude' => ''
            };

So, to get the file and sizes, I am using this in a separate perl script

my $lsResults = $cmd->ls("$chkdir");
#print Dumper($lsResults);
for my $filenm ( @{$lsResults->{file}} ) {
    print "Filename:  " . $filenm->{path} . "\n";
    print "    Size:  " . $filenm->{size} . "\n";
}
[download]

Results:

Filename:  /work/eng/feeds/customer_care/test/q_data_20111023.dat
    Size:  379085
[download]

What I need help is combining these scripts, combining the logic where: whatever directory I pass in, if the directory has sub-directories, list the sub-directory. If the directory has filenames, list the directory, file, and size.

So, in this case if $chkdir="/work/eng/feeds/customer_care/test"

Expected Output:

Directory: /work/eng/feeds/customer_care/test
Filename:  /work/eng/feeds/customer_care/test/q_data_20111023.dat
    Size:  379085
