Xpath not behaving for me in parsing basic html

I am trying to parse some basic html using xpath and running into issues. The returned output is always empty using what I am reading the xpath docs to say works. Below is my first attempt at making this work. Any help is appreciated as always guys and gals.

$html  = '<ul>';
$html .= '  <li id="stuff-12345"> some content here </li>';
$html .= '  <li id="stuff-54321"> some other content here </li>';
$html .= '</ul>';

    $dom = new DOMDocument(); 
    $dom->loadHTML($html);  
    $xpath = new DOMXPath($dom); 
    $result = $xpath->query('//ul/li'); 
    foreach($result as $e){
        echo $e->item(0)->nodeValue . "\n";
    }

DOMXPath::query returns a DOMNodeList. When you are doing

foreach($result as $e){

you are iterating over the DOMElement items a DOMNodeList. DOMElement does not have an item() method. Only DOMNodeList has that. Try with

foreach($result as $e){
    echo $e->nodeValue, PHP_EOL;
}
