I have never done what you're attempting to do, but as a stab in the dark, using the API docs, does echo $entry->textContent; work?

Adding an update. This is from the comments located on the docs page for DOMNode:

Hi!

Combining all th comments, the easiest way to get inner HTML of the node is to use this function:
```
<?php  function get_inner_html( $node ) { 
    $innerHTML= ''; 
    $children = $node->childNodes; 
    foreach ($children as $child) { 
        $innerHTML .= $child->ownerDocument->saveXML( $child ); 
    } 

    return $innerHTML;  }  ?>
```
Or, maybe a simpler method is just to do:
```
echo $domDocument->saveXML($entry);
```

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 = '<html> …'; // 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);
}
