[TriLUG] Perl LinkExtor

Hello TriLuggers,

I'm somewhat new to Perl, and I'm trying to get a script using 
HTML::LinkExtor to work... I know I'm doing something terribly wrong. 
What I want to do is call LinkExtor->parse() on a variable containing 
HTML content with links (to extract those links). Here's my code:

use LWP::Simple;
use HTML::LinkExtor;
use Data::Dumper;

my $url = 'http://some.web.site';

my $content = get $url;

print("fetched $url\n");

my $LinxEx = HTML::LinkExtor->new();

$LinkEx->parse($content);

print Dumper($LinkEX->links);

When I run it, the URL is fetched, but Perl complains that I can't call 
"Parse" on an undefined value. Obviously Parse() is expecting something 
other than what I'm giving it, but I can't figure out what... And I 
can't seem to find any documentation online about how to use the 
Parse() function... Does anyone know anything about HTML:LinkExtor? Or 
can anyone point me t a good resource on the web for learning Perl (or 
something that might explain what I'm doing wrong?) Thanks in advance!
