Does anyone know if it's possible to output an HTML document via the DomDocument::saveHTML() function without having the DTD, body, and html tags automatically added?
For example, I have this kind of html:
<form ...>
<div>...</div>
....
</form>
I would like to use DOMDocument to make some changes to this bit of HTML and then insert it into the middle of some HTML. The problem is that once I do this and use saveHTML(), I get:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<body>
<form ...>
<div>...</div>
....
</form>
</body>
</html>
This is obviously a problem if I want to put it in the middle of some other HTML.
I can't feed the file in using loadXML because of the validation errors. It would be great if there was convenient method a variable or method of some sort that could turn this feature off, rather than have to process the string output by saveHTML(), or any other method. Anyone?
<?php
class DOM extends DOMDocument {
public function saveHTML(){
return preg_replace("/(<\/?html>¦<!DOCTYPE.+¦<\/?body>)/", '', parent::saveHTML());
}
}
?>
Now, just call a new DOM() and use it as normal!
However, I would love it if there were a function in the DOMDocument that took care of this!

I must be missing something? If you are the one building the DOM document in the first place, then just don't add the elements ...
<?php
$doc = new DOMDocument();
$form = $doc->createElement('form');
$form = $doc->appendChild($form);
$div = $doc->createElement('div');
$div = $form->appendChild($div);
echo $doc->saveHTML();
?>
<form><div></div></form>
When reading in, the DTD, html, and body tags are automatically added...
Would be nice if the HTML section of DOMDocument did have an option to omit those automatic tags, at least if your HTML has a root element...
Oh well, if anyone knows of some obscure DOMDocument function/property that does this I'm all ears :)
$dom = new DOMDocument();
$dom->loadHTML($data);
$dom->firstChild->nextSibling->firstChild->textContent
No need for extending, same as $dom->saveHTML() but only with your original HTML, no extra tags!
