Re: Listing Keys in a specific element(s) in an array of hashs

My self-taught way was this, which means maybe others have better style...

for ( my $i=0; $i<=$#data; $i++ ) {
    my $href = $data[$i];
    for ( keys %$href ) {
        print "$_\n";
    }
}

Most monks would suggest the more natural foreach for something like this, as it tends to cut down on "one-off" errors. Also, it tends to be more intuitive (at least after you've learned Perl; I can see how your way would be more intutitive to a person coming from C or Java). `foreach my $href ( @data ) { for ( keys %$href ) { print "$_\n"; } }` [download] -Bryan	[reply] [d/l]
