Question

我正在使用curl file_get_contents但

来获取远程页面的源代码

问题是这个页面有很多iframe和广告，我想只得到这个页面的一小部分

页面源代码是这样的：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

我想要得到这个：

或

<script type="text/javascript"> chname="Zabava"; width="640"; height="385";</script><script type="text/javascript" src="http://castnowhd.com/js/embed.js"></script>

怎么做？

Answer 1

您可以使用DOMDocument::loadHTML()加载HTML，然后使用DOMXpath::query()进行搜索。有效模式可以是//iframe或//script。有关此类XPath搜索模式的更多信息，请参阅Mozilla Developer Network。

Answer 2

您可以使用简单的正则表达式click here for example执行此操作：

preg_match_all('#(<iframe.*/iframe>)#i', $code, $matches);
var_dump($matches);
preg_match_all('#(<script.*/script>)#i', $code, $matches);
var_dump($matches);

这将从源页面中提取（以非常愚蠢的方式）所有iframe和脚本元素。如果您需要更具体的匹配，我们需要更具体的标准，但这足以满足您的需求。
