Datastructure access

slatibart has asked for the wisdom of the Perl Monks concerning the following question:

This is probably a very easy question to answer but gives me headache. I have trouble to access a datastructure . This is what Data::Dumper tells me How do I access the DOMAIN structure correctly ?

$VAR1 = {
          'QUEUETIME' => '0.046',
          'PROPERTY' => {
                        'DOMAIN' => [
                                    'a.com',
                                    'b.com',
                                    'c.com'
                                  ],
                         'LIMIT' => [
                                   '1000'
                                  ],
                      }
        };

So that I could do something like this : for(@domains) {..}

One way to dereference the array: `use warnings; use strict; my %data = ( 'QUEUETIME' => '0.046', 'PROPERTY' => { 'DOMAIN' => [ 'a.com', 'b.com', 'c.com' ], 'LIMIT' => [ '1000' ], } ); my @domains = @{ $data{PROPERTY}{DOMAIN} }; for (@domains) { print "$_\n"; } # Same w/out intermediate array: # print "$_\n" for @{ $data{PROPERTY}{DOMAIN} }; __END__ a.com b.com c.com` [download] See also: perldsc	[reply] [d/l]
