DESCRIPTION ^

This plugin add nothing syntax to HTML::Template but add some methods usefull for parsing html template in an environment where web pages are built embedding more little html templates (have you see my HTML::Puzzle CPAN module?).

It add a costructor parameter "autoDeleteHeader" that, is set to 1, automatically remove html header returning only html code inside BODY tag.

If you have see HTML::Template::Extension::CSTART plugin this is equivalent to

 <HTML>
        <HEAD>
        </HEAD>
        <BODY>
                <TMPL_CSTART>
                ...
                </TMPL_CSTART>
        </BODY>
 </HTML>

But more than this a "header" method will be added to return removed header.

It also have a "js_header" method to return javascript code present in the header.
