PHP DOM get nodevalue html? (without stripping tags)

Question

I am trying to get the innerhtml of div tags in a file using nodeValue, however this code is outputting only plain text and seems to strip out all html tag from inside the d

Instead of:

echo $entry->nodeValue;

You have to use:

echo $doc->saveXML($entry);

Here is a more complete example that might help others too, $doccontent is the HTML block as a string:

$doccontent = ' …'; // your html string
$dom = new DOMDocument;
$internalErrors = libxml_use_internal_errors(true); // prevent error messages 
$content_utf = mb_convert_encoding($doccontent, 'HTML-ENTITIES', 'UTF-8'); // correct parsing of utf-8 chars
$dom->loadHTML($content_utf);
libxml_use_internal_errors($internalErrors); // prevent error messages 
$specialdiv = $dom->getElementById('xdiv');
if(isset($specialdiv))
{
    echo $dom->saveXML($specialdiv);
}
