return multiple nodes with xpath

Question

how do i return more than one node on a page? here is the code i am using, but it only returns the 1st node found.

$dom = new DOMDocument;
$dom->loadHTMLFile($URL);

$xpath  = new DOMXpath($dom);
$users= $xpath->query('//b[@class="xc_user"]');

echo $users->item(0)->nodeValue;

Answer 1

$users is a DOMNodeList, which you can iterate over:

foreach($users as $node) {
    echo $node->nodeValue;
}
