Excellent Maresia! Here's a couple of different ways you can do it. Note that double-quotes automatically 'interpolate' variables (ie. expands variables to their values), so you can even do "$rows\n"; instead of $rows."\n" :)

my %my_data = ( names => $some_data);
my $my_data_ref = \%my_data;

my @all_names = split /\n/, $my_data_ref->{names};

for (@all_names){
    print "$_\n";
}

# or even skip creating the @all_names array altogether

print "$_\n" for split /\n/, $my_data_ref->{names};

I wouldn't recommend the latter unless you're really just doing something with the extracted information immediately on the spot.
