php DOMDocument: return nodeValue including childNode

Question

file.html

<div>
    <a href="">apple</a>
</div>

$html = new DOMDocument();
$html->preserveWhiteSpace = true;
$html->loadHTML( file_get_contents('file.html') );
$nodes =  $html->getElementsByTagName('*');

foreach($nodes as $i=>$node) {
     if($node->nodeName == 'div')
     echo $node->nodeValue;
}

this returns 'apple'. How do I get the child node including the child node's value, as in:
<a href="#">apple</a>

What you want is the 'innerHTML' of the node, which PHP DOM doesn't support. php.net/manual/en/book.dom.php#89802 details how to fake it. — Marc B

@MarcB There is a way, it's just not as obvious. See the answer I just posted. — onteria_

Thanks, but onteria's answer looks to be a much cleaner solution. — Marc B

You can pass the a dom node to DOMDocument::saveXML and it will spit out the actual HTML instead:

$html = new DOMDocument();
$html->preserveWhiteSpace = true;
$html->loadHTML( file_get_contents('file.html') );
$nodes =  $html->getElementsByTagName('*');

foreach($nodes as $i=>$node) {
     if($node->nodeName == 'div') {
       //Navigate to the specific element you want
       //then pass it to saveXML
       echo $html->saveXML($node->childNodes->item(1));
     }
}
