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.
