html::elementraw

HTML::ElementRaw(3pm)					User Contributed Perl Documentation				     HTML::ElementRaw(3pm)

NAME

       HTML::ElementRaw - Perl extension for HTML::Element(3).

SYNOPSIS

	 use HTML::ElementRaw;
	 $er = new HTML::ElementRaw;
	 $text = '<p>I would like this &nbsp; HTML to not be encoded</p>';
	 $er->push_content($text);
	 $h = new HTML::Element 'h2';
	 $h->push_content($er);
	 # Now $text will appear as you typed it, non-escaped,
	 # embedded in the HTML produced by $h.
	 print $h->as_HTML;

DESCRIPTION

       Provides a way to graft raw HTML strings into your HTML::Element(3) structures.	Since they represent raw text, these can only be leaves in
       your HTML element tree.	The only methods that are of any real use in this degenerate element are push_content() and as_HTML().	The
       push_content() method will simply prepend the provided text to the current content.  If you happen to pass an HTML::element to
       push_content, the output of the as_HTML() method in that element will be prepended.

REQUIRES

       HTML::Element(3)
