As of PHP 5.4 and Libxml 2.6, there is currently simpler approach:
when you load html as this
$html->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
in the output, there will be no doctype, html or body tags

When saving HTML fragment initiated with LIBXML_HTML_NOIMPLIED option, it will end up being "broken" as libxml requires root element. libxml will attempt to fix the fragment by adding closing tag at the end of string based on the first opened tag it encounters in the fragment.
For an example:
<h1>Foo</h1><p>bar</p>
will end up as:
<h1>Foo<p>bar</p></h1>
Easiest workaround is adding root tag yourself and stripping it later:
$html->loadHTML('<html>' . $content .'</html>', LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
$content = str_replace(array('<html>','</html>') , '' , $html->saveHTML());

If you load HTML from a string ensure the charset is set.
<?php
...
$html_src = '<html><head><meta content="text/html; charset=utf-8" http-equiv="Content-Type"></head><body>';
$html_src .= '...';
...
?>
Otherwise the charset will be ISO-8859-1!

To avoid script tags from being output as <script />, you can use the DOMDocumentFragment class:
<?php
$doc = new DOMDocument();
$doc -> loadXML($xmlstring);
$fragment = $doc->createDocumentFragment();
/* Append the script element to the fragment using raw XML strings (will be preserved in their raw form) and if succesful proceed to insert it in the DOM tree */
if($fragment->appendXML("<script type='text/javascript' src='$source'></script>") {
$xpath = new DOMXpath($doc);
$resultlist = $xpath->query("//*[local-name() = 'html']/*[local-name() = 'head']"); /* namespace-safe method to find all head elements which are childs of the html element, should only return 1 match */
foreach($resultlist as $headnode) // insert the script tag
$headnode->appendChild($fragment);
}
$doc->saveXML(); /* and our script tags will still be <script></script> */
?>

If you want a simpler way to get around the <script> tag problem try:
<?php
$script = $doc->createElement ('script');\
// Creating an empty text node forces <script></script>
$script->appendChild ($doc->createTextNode (''));
$head->appendChild ($script);
?>

To solve the script tag problem just add an empty text node to the script node and DOMDocument will render <script src="your.js"></script> nicely.

XHTML:
If the output is XHTML use the function saveXML().
Output example for saveHTML:
<select name="pet" size="3" multiple>
<option selected>mouse</option>
<option>bird</option>
<option>cat</option>
</select>
XHTML conform output using saveXML:
<select name="pet" size="3" multiple="multiple">
<option selected="selected">mouse</option>
<option>bird</option>
<option>cat</option>
</select>

If created your DOMDocument object using loadHTML() (where the source is from another site) and want to pass your changes back to the browser you should make sure the HTTP Content-Type header matches your meta content-type tags value because modern browsers seem to ignore the meta tag and trust just the HTTP header. For example if you're reading an ISO-8859-1 document and your web server is claiming UTF-8 you need to correct it using the header() function.
<?php
header('Content-Type: text/html; charset=iso-8859-1');

// Using DOM to fix sloppy HTML.
// An example by Tyson Clugg <[email protected]>

// vim: syntax=php expandtab tabstop=2
function tidyHTML($buffer)
{
// load our document into a DOM object
$dom = @DOMDocument::loadHTML($buffer);
// we want nice output
$dom->formatOutput = true;
return($dom->saveHTML());
}
// start output buffering, using our nice
// callback funtion to format the output.

<html>
<p>It's like comparing apples to oranges.
</html>
<?php
// this will be called implicitly, but we'll
// call it manually to illustrate the point.
ob_end_flush();
?>
The above code takes out sloppy HTML:
<html>
<p>It's like comparing apples to oranges.
</html>
And cleans it up to the following:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>It's like comparing apples to oranges.
</p></body></html>

In this post http://softontherocks.blogspot.com/2014/11/descargar-el-contenido-de-una-url_11.html I found a simple way to get the content of a URL with DOMDocument, loadHTMLFile and saveHTML().
function getURLContent($url){
$doc = new DOMDocument;
$doc->preserveWhiteSpace = FALSE;
@$doc->loadHTMLFile($url);
return $doc->saveHTML();
}
