html::linkextor
HTML::LinkExtor(3) User Contributed Perl Documentation HTML::LinkExtor(3)
NAME
HTML::LinkExtor - Extract links from an HTML document
SYNOPSIS
require HTML::LinkExtor;
$p = HTML::LinkExtor->new(&cb, "http://www.perl.org/");
sub cb {
my($tag, %links) = @_;
print "$tag @{[%links]}
";
}
$p->parse_file("index.html");
DESCRIPTION
HTML::LinkExtor is an HTML parser that extracts links from an HTML document. The HTML::LinkExtor is a subclass of HTML::Parser. This means
that the document should be given to the parser by calling the $p->parse() or $p->parse_file() methods.
$p = HTML::LinkExtor->new
$p = HTML::LinkExtor->new( $callback )
$p = HTML::LinkExtor->new( $callback, $base )
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 URI 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.
$p->links
Returns a list of all links found in the document. The returned values will be anonymous arrays with the following elements:
[$tag, $attr => $url1, $attr2 => $url2,...]
The $p->links method will also truncate the internal link list. This means that if the method is called twice without any parsing
between them the second call will return an empty list.
Also note that $p->links will always be empty if a callback routine was provided when the HTML::LinkExtor was created.
EXAMPLE
This is an example showing how you can extract links from a document received using LWP:
use LWP::UserAgent;
use HTML::LinkExtor;
use URI::URL;
$url = "http://www.perl.org/"; # for instance
$ua = LWP::UserAgent->new;
# Set up a callback that collect image links
my @imgs = ();
sub callback {
my($tag, %attr) = @_;
return if $tag ne 'img'; # we only look closer at <img ...>
push(@imgs, values %attr);
}
# Make the parser. Unfortunately, we don't know the base yet
# (it might be different from $url)
$p = HTML::LinkExtor->new(&callback);
# Request document and parse it as it arrives
$res = $ua->request(HTTP::Request->new(GET => $url),
sub {$p->parse($_[0])});
# Expand all image URLs to absolute ones
my $base = $res->base;
@imgs = map { $_ = url($_, $base)->abs; } @imgs;
# Print them out
print join("
", @imgs), "
";
