　　网页抓取 加密html(我有这个代码获取页面的HTML源代码：我想从中搜集一些内容

)

　　我有这段代码来获取页面的 HTML 源代码：

　　1$page = file_get_contents('http://example.com/page.html');

2$page = htmlentities($page);

3

　　我想从中采集一些内容。例如，假设页面的源收录：

　　1technorati.com

2Connection failedPinging icerocket.com

3Connection failedPinging weblogs.com

4DonePinging newsgator.com

5DonePinging blo.gs

6DonePinging feedburner.com

7DonePinging blogstreet.com

8DonePinging my.yahoo.com

9Connection failedPinging moreover.com

10Connection failedPinging newsisfree.com

11Done

　　有没有办法可以从源代码中删除它并将其存储在一个变量中，所以它看起来像这样：

　　连接失败

　　连接失败

　　完毕

　　等等。

　　因为页面是动态的，这就是我遇到问题的原因。我可以搜索源中的每个站点吗？但是那之后我如何得到结果呢？（连接失败/完成）

　　谢谢您的帮助！

　　我尝试使用简单的 HTML DOM PHP 库来抓取多个站点，可在此处获得：

　　然后使用这样的代码：

　　1find('h2') as $heading) { //for each heading

16 //find all spans with a inside then echo the found text out

17 echo preg_replace($pat, $rep, $heading->find('span a', 0)->plaintext) . "\n";

18}
