Do I gain something when I transform my $url like this: $url = URI->new( $url )?
#!/usr/bin/env perl
use warnings; use strict;
use 5.012;
use URI;
use XML::LibXML;
my $url = 'http://stackoverflow.com/';
$url = URI->new( $url );
my $doc = XML::LibXML->load_html( location => $url, recover => 2 );
my @nodes = $doc->getElementsByTagName( 'a' );
say scalar @nodes;
