In PHP, what is the best practice for iterating through a DOMNodeList returned by xpath::query()?

When iterating through a DOMNodeList returned by xpath::query(), it is best practice to use a foreach loop to iterate over each DOMNode in the list. This allows you to easily access and manipulate each node without having to worry about the index or length of the list. 

$dom = new DOMDocument();
$dom->loadHTML($html);

$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//div[@class="example"]');

foreach ($nodes as $node) {
    // Do something with each $node
    echo $node->nodeValue;
}
