PHP DOMDocument without the DTD, head, and body tags?

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

@Wrikken所说的，或者，对于PHP <5.3.6，只需使用正则表达式即可：

$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 (eg 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);
}
