You can do a schwartzian transform ....
@hosts = (blah..blah..blah);
my @sorted =
map { $_->[0] }
sort { $a->[1] cmp $b->[1] }
map { [$_,$_->{name} }
@hosts;
foreach my $h (@sorted) {
foreach my $k (keys %$h) {
print "key $k has the value $h->{$k}\n";
}
print "New host\n";
}
wah lah! ... i am using the schwartzian transform 'cos i kinda just got round
to reading about it in effective perl and i think it is kewl ... anyone know a
better way of implementing this solution feel free to suggest as well ...
