=head1 NAME
Template::Plugin::HTML::Strip - HTML::Strip filter for Template Toolkit
=head1 SYNOPSIS
[% USE HTML.Strip %]
[% FILTER html_strip %]
<title>People for the Preservation of Presentational Markup</title>
<h1>HTML::Strip - A cause for concern?</h1>
[% END %]
[% USE HTML.Strip 'strip'
striptags = [ 'script' 'iframe' ]
emit_spaces = 0
%]
[% FILTER strip %]
<p>A call to arms against the removal of our elements!</p>
[% END %]
=head1 DESCRIPTION
This module is a Template Toolkit dynamic filter, which uses HTML::Strip
to remove markup (primarily HTML, but also SGML, XML, etc) from filtered
content during template processing.
By default, the installed filter's name is 'html_strip'. This can be
changed by specifying a new name as the first positional argument
during plugin usage:
[% USE HTML.Strip 'strip' %]
[% '<div>Our very existence is under threat.</div>' | strip %]
The filter can optionally take configuration options, which will be
passed to HTML::Strip's constructor method:
[% USE HTML.Strip
striptags = [ 'applet' 'strong' ]
emit_spaces = 0
%]
[% FILTER html_strip %]
<strong>Are we next!?</strong>
[% END %]
For more details on available configuration options, please refer to
L<HTML::Strip|HTML::Strip>.
=head1 METHODS
=head2 init
Creates a dynamic filter and installs the filter under the value provided
for the first positional argument, otherwise uses 'html_strip'.
=head2 filter
Receives a reference to the plugin object, along with the text to be
filtered and configuration options. Using HTML::Strip, returns the filtered
(stripped) text.
