如果用php抓取微信文章正文?


我是一个新手,想使用php抓取微信页面的正文和标题,标题直接用正则表达式 |<title>(.*?)<\/title>|i 就抓取到了,但是正文我想的是 |>(.*?)<\/|i 匹配标签间的内容,再去掉空格,但是还是会匹配到一堆标签,是怎么回事?或者说有其他更好的方法吗?求指教!

这是一般的微信文章内容链接

正则表达式 php 微信

没必要用正则表达式的,可以用PHP像jQuery那样直接操作DOM的,你可以参考一下。 http://www.cnphp.info/php-simple-html-dom-parser-intro.html

这种问题,放弃用正则吧,要真正完备的你可能得写一篇文章那样长。但 html 已经是结构化的了,找个 html 解析库就行了,我刚用 firebug 粗略的看了下,正文是在 id 为 page-content 的 div 里。

当然,如果我所看到的是受 js 影响后的页面状态,那你可能得挂个浏览器内核来帮你获取到最终页面状态了。幸好,这个有很多开源的。
