直接用zend-dom吧,方便多了!
http://framework.zend.com/manual/2.3/en/modules/zend.dom.query.html
引入不用教了吧?
<code>$url = 'http://www.baidu.com';$ch = curl_init();curl_setopt($ch, CURLOPT_FILE, fopen('php://stdout', 'w'));curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);curl_setopt($ch, CURLOPT_URL, $url);$html = curl_exec($ch); curl_close($ch);// create document object model$dom = new DOMDocument();// load html into document object model@$dom->loadHTML($html);// create domxpath instance$xPath = new DOMXPath($dom);// get all elements with a particular id and then loop through and print the href attribute$elements = $xPath->query('//*[@id="lg"]/img/@src');foreach ($elements as $e) { echo ($e->nodeValue);}</code>
差不多这样的
