Re: How do I follow links stored in an array?

First you'd better make sure that there are some links in @links to follow.

#jump through tags until you get 'h1'
while( my $title = $p->get_tag( 'h1' )) {
last if $title->[1]->{class} eq 'h1';
}

Since there are no <h1> elements in the document, that code jumps to the end of string.

You can simply do:

$p->get_tag('/h2');

to get to the section of the document you are interested in. No loop needed.

# look through the tokens until you hit the end of 'h1'
my @links;
while ( my $token = $p->get_token ) {
last if $token->[0] eq 'E' && $token->[1] eq 'h1';
-----------------------------------------------------^^^^
Suppose you mean 'div' ...

# now follow the links

Yes, but first make sure that @links contains what you expect.

print "$_\n" for @links;

If it does, you can start working with the last section of your script.
