I am able to manage to create the data structure as below.

$VAR1 = {
  '99155' => {
              'PR' => [
                         'state_name=Puerto Rico',
                         'county_names_all=Adjuntas|Utuado',
                       ],
              'AK' => [
                         'state_name=Alaska',
                         'county_names_all=Ketchikan Gateway|Prince of
+ Wales-Hyder',
                       ],
              'WA' => [
                         'state_name=Washington',
                         'county_names_all=Pend Oreille|Spokane|Lincol
+n|Adams',
                         'comments=America/Los_Angeles'
                       ]
            },
  '26134' => {
               'WV' => [
                          'state_name=West Virginia',
                          'county_names_all=Wirt|Wood|Jackson|Ritchie|
+Calhoun',
                          'comments=America/New_York'
                        ]
                 }
};

But Now I Need to get all the "state_name" in above structure into an array.

 @array = ('Puerto Rico', 'Alaska', 'Washington', 'West Virginia');

and another array as (Filter "state_name" for which "comments" is present)

 @array = ('Puerto Rico', 'Alaska');

So far i tried 

for my $outerkey (keys %hash) { 
    for my $innerkey (keys $hash{$outerkey}) { 
       print join(', ', @{ $hash{$outerkey}{$innerkey} } );
       push( @{ $hash{$outerkey}{$innerkey} }, @array);
    } 
}
