perl遍历哈希的所有健和值

my %h=("001",{name,"李白",age,"18",height,"185",weight,"60kg"},"002",{name,"杜甫",age,"35",height,"175",weight,"50kg"},"003",{name,"王维",age,"50",height,"180",weight,"80kg"});
dumplist(\%h);
sub dumplist
{
    my $LIST = shift;
    my $legend = 0;
    foreach $item (sort keys %$LIST)
    {
        print "$item:\n";
        my @attributes = ();
        my @legen = ();

        foreach $attr (sort keys %{$$LIST{$item}})
        {
            push(@legen, $attr);
            push(@attributes, $LIST->{$item}{$attr});
            print "$attr=$LIST->{$item}{$attr}\n";
        }
        print "\n";

    }
}
