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.
