How to save xpath query data to saveHTML with HTML tags?

Question

I'm trying to understand how I can save the html string found by query so that I can access it's elements.

I'm using the following query to find the below ul list.

$data = $xpath->query('//h2[contains(.,"Hurricane Data")]/following-sibling::ul/li');

<h2>Hurricane Data</h2>
<ul>
    <li><strong>12 items</strong> found, see <a href="/link">here</a>for more information</li>
    <li><strong>19 items</strong> found, see <a href="/link">here</a>for more information</li>
    <li><strong>13 items</strong> found, see <a href="/link">here</a>for more information</li>
</ul>

If I print_r($data), I get the following DOMNodeList Object ( [length] => 3 ) which refers to the 3 elements found.

If I foreach() into the $data I get a DOMElement Object with all 3 li data.

What I'm trying to accomplish is to put each li data into an accessible array, but I want to parse the html strong & a tags inside too.

Now, I've already did everything I want to do, except the strong and a tags aren't being inserted into the arrays, here is what I've come up with.

$string = [];
$query = $xpath->query('//h2[contains(.,"Hurricane Data")]/following-sibling::ul/li');
foreach($query as $values){
    $try = new \DOMDocument;
    $try->loadHTML(mb_convert_encoding($values->textContent, 'HTML-ENTITIES', 'UTF-8'));

    $string[] = $try->saveHTML();
}

echo $string[0];
// outputs = 12 items found, see here for more information
// no strong tags, no hyperlinks

You don't need to reprocess the data, you can just say to save this particular node...

foreach($query as $values){    
    $string[] = $doc->saveHTML($values);
}

Where $doc is the document used as the basis for your XPath query.
