Parsing XML-like document with PHP DOMDocument

I try to parse the XML-like structure of an EPUB index with PHP DOMDocument as

$doc = new DOMDocument();
$xml = '
      <navPoint playOrder="1" id="np-1">
        <navLabel>
          <text>I</text>
        </navLabel>
        <content src="/1.html"/>
      </navPoint>
      <navPoint playOrder="2" id="np-2">
        <navLabel>
          <text>II</text>
        </navLabel>
        <content src="/2.html"/>
      </navPoint>
';

@$doc->loadHTML('<?xml encoding="utf-8" ?>
<html><head></head><body>' . $xml . '</body></html>');

$output = $doc->getElementsByTagName('navPoint');

print_r($output);

but it returns

DOMNodeList Object
(
    [length] => 0
)

What did I do wrong that it does not parse it as a straightforward HTML document?

P.S. I tried PHP XML parser too, but as it is not an actual XML document, it gives errors because of an invalid XML. Therefore, I prefer to treat it as an HTML document.

You're looking for loadXML, not loadHTML.

No need to surround everything with HTML tags, just add a dummy <root> item instead, because any valid XML document must have one (you can also add it to the $xml variable itself).

Also, using @ before function calls should be avoided in 99% cases, it prevents you from seeing/understanding what's wrong.

The following should do it:

$doc->loadXML('<root>' . $xml . '</root>');
