Assuming I understand the way you structured your hash correctly, let me suggest this solution:
my %domain_stats = ( 'www.perlmonks.com' => { 'country' => 'USA', # ... other very much needed fields ... }, 'www.google.ca' => { 'country' => 'Canada', }, 'www.foobar.com' => { # does this one exist even? ;) 'country' => 'Nebukadnezaria', }, ); for (sort {$domain_stats{$a}{country} cmp $domain_stats{$b}{country}} +keys %domain_stats) { print "Domain: $_; Country: $domain_stats{$_}{country}\n"; }
This prints out the following:
Domain: www.google.ca; Country: Canada Domain: www.foobar.com; Country: Nebukadnezaria Domain: www.perlmonks.com; Country: USA
