NAME

SYNOPSIS

  use HTML::ResolveLink;

  my $resolver = HTML::ResolveLink->new(
      base => 'http://www.example.com/foo/bar.html',
      callback => sub {
         my($uri, $old) = @_;
         # ...
      },
  );
  $html = $resolver->resolve($html);

DESCRIPTION

For example. when you have

  <a href="foo.html">foo</a>
  <img src="/bar.gif" />

and use "http://www.example.com/foo/bar" as "base" URL, you'll get:

  <a href="http://www.example.com/foo/foo.html">foo</a>
  <img src="http://www.example.com/bar.gif" />

If the parser encounters "<base>" tag in HTML, it'll honor that.

METHODS

new

  my $resolver = HTML::ResolveLink->new(
      base => 'http://www.example.com/',
      callback => \&callback,
  );
    

"base" is a required parameter, which is used to resolve the relative URI found in the document.

"callback" is an optional parameter, which is a callback subroutine reference which would take new resolved URI and the original path as arguments.

Here's an example code to illustrate how to use callback function.

  my $count;
  my $resolver = HTML::ResolveLink->new(
      base => $base,
      callback => sub {
          my($uri, $old) = @_;
          warn "$old is resolved to $uri";
          $count++;
      },
  );

  $html = $resolver->resolve($html);

  if ($count) {
      warn "HTML::ResolveLink resolved $count links";
  }
    

resolve

  $html = $resolver->resolve($html);
    

Resolves relative URI found in $html into absolute and returns a string containing rewritten one.

resolved_count

  $count = $resolver->resolved_count;
    

Returns how many URIs are resolved during the previous resolve method call. This should be called after the resolve, otherwise returns undef.
