Dear all, I write this code to extract the widget from this page:http://www.widgetbox.com/widget/accuwidget The widget information is hidden under the tag <iframe> and is inside the src. I try using this code and it always show me error of: Fatal error: Call to undefined method DOMNodeList::getAttribute() <?php get(); function get(){ $url = "http://www.widgetbox.com/widget/accuwidget"; $tidy = new tidy(); $repaired = $tidy->repairfile($url); //The code is dirty, so it need to be tidy $xml = new DOMDocument(); $xml->loadHTML($repaired); $xpath = new DOMXpath($xml); $cloud = $xpath->query("//div[@id='preview-div']/div/iframe"); $widget = $cloud->getAttribute("src"); echo $widget; } ?> Sorry that I didn't input the code of the page i want to scrape the information. It's just that the code is so long. Thank you all in advance
