Get contents of BODY without DOCTYPE, HTML, HEAD and BODY tags

Question

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.

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.

Answer 1

Since the substr() method seemed to be too much for some to swallow, here is a DOM parser method:

$d = new DOMDocument;
$mock = new DOMDocument;
$d->loadHTML(file_get_contents('/path/to/my.html'));
$body = $d->getElementsByTagName('body')->item(0);
foreach ($body->childNodes as $child){
    $mock->appendChild($mock->importNode($child, true));
}

echo $mock->saveHTML();

Answer 2

$site = file_get_contents("http://www.google.com/");

preg_match("/<body[^>]*>(.*?)<\/body>/is", $site, $matches);

echo($matches[1]);
