在网上查看了很多相关资料,但都是PHP用xpath解析xml的,请问PHP有没有相关的函数或是类库能解析html吗?谢谢

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
