=head1 NAME
HTML::LinkExtor - Extract links from an HTML document
=head1 SYNOPSIS
require HTML::LinkExtor;
$p = HTML::LinkExtor->new(\&cb, "http://www.perl.org/");
sub cb {
my($tag, %links) = @_;
print "$tag @{[%links]}\n";
}
$p->parse_file("index.html");
=head1 DESCRIPTION
I is an HTML parser that extracts links from an
HTML document. The I is a subclass of
I. This means that the document should be given to the
parser by calling the $p->parse() or $p->parse_file() methods.

The constructor takes two optional arguments. The first is a reference
to a callback routine. It will be called as links are found. If a
callback is not provided, then links are just accumulated internally
and can be retrieved by calling the $p->links() method.
The $base argument is an optional base URL used to absolutize all URLs found.
You need to have the I module installed if you provide $base.
The callback is called with the lowercase tag name as first argument,
and then all link attributes as separate key/value pairs. All
non-link attributes are removed.
