Get contents of BODY without DOCTYPE, HTML, HEAD and BODY tags
<p>Sorry for the long title, but it kind of says it all clearly. What I am trying to do is include an HTML file within a PHP system (not a problem) but that HTML file also needs to be usable on its own, for various reasons, so I need to know how I can strip the doctype, html, head and body tags in the context of the PHP include, if that's possible.</p>

<p>I'm not particularly good at PHP (doh!) so my searches of the php manual and on the web hasn't made me figure this out. Meaning that any help or reading tips, or both, are much appreciated.</p>
