NAME

HTML::ResolveLink - Resolve relative links in (X)HTML into absolute URI

SYNOPSIS

  use HTML::ResolveLink;

  my $resolver = HTML::ResolveLink->new(
      base => 'http://www.example.com/foo/bar.html',
  );
  $html = $resolver->resolve($html);

  if ($resolver->resolved_count) {
      ...
  }

DESCRIPTION

HTML::ResolveLink is a module to rewrite relative links in XHTML or HTML into absolute URI.

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/',
  );

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

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.
