Send ID with DOMNodeList - php

Question

I have this splendid code
public static function city($city)
{
$html = file_get_contents("http://www.example.com/?=$city");
libxml_use_internal_errors(true);
$doc = new \DOMDocument();
if($doc->loadHTML($html))
{
$result = new \DOMDocument();
$xpath = new \DOMXPath($doc);
$movies = $xpath->query("/html/body");
$url = $xpath->query("/html/body/a/#");
return $movies;
}
}
This function returns as expected a list om movies, and i fetch them with $movies->nodeValue
But i want to send an ID as well.
So i try to add this snipp (to explode the ID from the URL):
foreach($url as $MovieId){
$data=parse_url($MovieId->nodeValue, PHP_URL_QUERY);
$splittedstring=explode("&",$data);
$id[] = substr(strstr($splittedstring[0], "="),1);
}
And this works perfect when i just echo it like this:
$i=0;
echo '<ul>';
foreach ($movies as $key => $movie) {
echo '<li>'.$movie->nodeValue . '</li>';
$i++;
}
echo '</ul>';
But when trying to send it from the Model, to the view with:
$data = new stdClass;
$data->movie_title = $movies;
$data->movie_id = $id;
return $data;
I get: Notice: Undefined property: DOMNodeList::$nodeValue...
My question: How can i either
convert the $movies to a stdClass
send the id with the object(DOMNodeList) (and retrieve it how?)
