PHP DOMDocument without the DTD, head, and body ta

Question

Is it possible to use the DOMDocument class and not allow it to add doc type declarations, head, and body tags? I am writing my current bit of code for a server side include, and it is being rendered on an already well formed page. I don't need additional tags.

Answer 1

What @Wrikken said or, for PHP < 5.3.6, just use a regular expression:

$html = preg_replace('~<(?:!DOCTYPE|/?(?:html|body))[^>]*>\s*~i', '', $dom->saveHTML());

Answer 2

Since PHP 5.3.6, you can use a node in echo $DOMDocument->saveHTML($the_node_you_want_to_show), before that, I've abused ->saveXML() with minor fixes. You must however have 1 surrounding included node (e.g. output is <div>...somecontent and nodex....</div>, or loop through the nodes children if you don't want have 1 surrounding tag;

$html = '';
foreach($rootnode->childNodes as $node){
    $html .= $rootnode->ownerdocument->saveHTML($node);
}
