HTML::RewriteAttributes::Links(3pm)			User Contributed Perl Documentation		       HTML::RewriteAttributes::Links(3pm)

NAME

       HTML::RewriteAttributes::Links - concise link rewriting

SYNOPSIS

	   # up for some HTML::ResolveLink?
	   $html = HTML::RewriteAttributes::Links->rewrite($html, "http://search.cpan.org");

	   # or perhaps HTML::LinkExtor?
	   HTML::RewriteAttributes::Links->rewrite($html, sub {
	       my ($tag, $attr, $value) = @_;
	       push @links, $value;
	       $value;
	   });

DESCRIPTION

       "HTML::RewriteAttributes::Links" is a special case of HTML::RewriteAttributes for rewriting links.

       See HTML::ResolveLink and HTML::LinkExtor for examples of what you can do with this.

METHODS

   "new"
       You don't need to call "new" explicitly - it's done in "rewrite". It takes no arguments.

   "rewrite" HTML, (callback|base)[, args] -> HTML
       See the documentation of HTML::RewriteAttributes.

       Instead of a callback, you may pass a string. This will mimic the behavior of HTML::ResolveLink -- relative links will be rewritten using
       the given string as a base URL.
