Hello all,

As the other monks have answered your question, I thought I might offer a tip. When printing the contents of an array, or stringifying an array in general, it's a lot easier (and more idiomatic) to use join.

So instead of:

my $yy = $test->{'divs'};
foreach my $xx (@$yy) { print $xx."\n";}

try:

my $yy = $test->{'divs'};
print ((join "\n", @$yy) . "\n");

The extra parens are required to prevent print being interpreted as a function and seeing only the join, not the extra "\n".

You also might want to explore more about {} syntax for dereferencing structures. The Camel Book has an excellent overview of the various syntaxes. Here's an example, eliminating the need for $yy:

foreach my $xx (@{$test->{divs}}) { print $xx."\n";}
print ((join "\n", @{$test->{divs}}) . "\n");

Of course, it can be argued that these sorts of idioms reduce legibility. It's a matter of taste.
