PHP 文件在载入xml文件和创建DOMDocument 对象后，就可以开始建立DOMXPath 对象。...建立形式如下： $xpath = new DOMXPath($xmldoc); 建立 DOMXPath 对象后，就可以开始使用 DOMXPath::query()方法，找到你需要的元素： $item =...php $xmldoc = new DOMDocument(); //加载文件 $xmldoc- load("words.xml"); //使用xpath查询 $xpath = new DOMXPath...($xmldoc);//创建DOMXPath对象 $node_list = $xpath- query("/words/word/ch");//查询ch这个元素，返回值为DOMNodeList对象 echo
想要使用xpath来解析html内容, PHP自带两个对象 DOMDocument，DOMXpath，其中初始化 loadHtml一般都会报很多警告，但是并不影响使用，用@屏蔽错误。.../** * 初始化DOMXpath对象 * * @param [type] $content 网页内容 * @param [array] $pathinfo 匹配信息 *...= new \DOMDocument(); @$dom- loadHtml($content); $dom- normalize(); $xpath = new \DOMXpath
file_get_contents('http://www.example.com'); $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath...file_get_contents('http://www.example.com'); $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath
dom = new DOMDocument(); // 从一个字符串加载HTML @$dom->loadHTML($html); // 使该HTML规范化 $dom->normalize(); // 用DOMXpath...加载DOM，用于查询 $xpath = new DOMXPath($dom); // 获取对应的xpath数据 $hrefs = $xpath->query("//script[@type='application...length; $i++) { $href = $hrefs->item($i); $json = $href->nodeValue; } 类库的用法自己可以看一下手册，使用 DOMXPath
