php - 如何使用 PHP 解析网页？

Question

我正在学习php。我已经学习了一些基础知识。现在我渴望学习网页解析。
我想解析这个页面http://www.icc-cricket.com/rankings/team-rankings/test
我想单独解析这个

Rank Team Matches Points Rating
1 South Africa 24 3240 135

Answer 1

我会推荐 Symfony2 DomCrawler 组件http://symfony.com/doc/current/components/dom_crawler.html

Answer 2

如果你了解基本的 PHP，我会推荐你​​使用这个框架：http ://simplehtmldom.sourceforge.net/

它使用简单。

Answer 3

根据我的观点，它无法解析，因为该表是通过 AJAX 调用附加的。我们可以看到这样的空标签：

<section class="standings"></section>

如果我这一切都错了，请纠正我

谢谢

Answer 4

您可以查看http://simplehtmldom.sourceforge.net/，它允许您相当轻松地解析 HTML 页面。

也就是说，应该始终关注服务是否提供提要，因为解析它们既不容易出错，效率更高，而且（通常）变化不大。HTML 标记会随着时间而改变，导致您的 dom 查询变得无效。

Answer 5

似乎这些分数是通过 ajax 附加到页面上的。所以你不能直接解析这个链接来获得你的排名。似乎请求被发送到 http://cma.icc-cricket.com/api/getRankings?callback=onRankings&_1375776810417=

所以你需要发出类似的请求并处理数据。来自网址的结果：

但是如果你只想学习 HTML 解析，那么你也可以使用Ganon
