Question

Ho can I get the data-time value from the following code with xpath->query in php

Answer 1

Try this, using DOMDocument and DOMXPath

$str = '<span class="timestamp" data-time="1395846963">33m</span>';

$DOM = new DOMDocument();
$DOM->loadHTML($str);

$XPATH = new DOMXPATH($DOM);

$r = $XPATH->query("//span/@data-time");

var_dump($r->item(0)->nodeValue);
