正则php咨询

最近想用PHP写一个收集站内网址列表的程序，如果要是为每个独立的网站都配置单独的规则程序就显得不够智能，所以想一次性写一个智能点的，我的思路是，程序从一个入口进入“www.xxx.com”后用FILE_GET_CONTENT 或CURL获取该页的HTML，然后通过正则分析出所有的链接保存到数组中。

这个时候问题就出现了，因为HTML写法问题，会出现很多情况，下面举例说明。

标题
标题
标题
标题
标题
标题
标题

等等吧，还有很多情况就不逐一写出来了，由于FILE_GET_CONTENT是必须能够访问到该页面才可以返回HTML，但是如果在访问之前不处理的话，就会出现无法访问被跳过的现象，于是我就根据一定情况对上述地址进行拼接使其能够被访问到。

但是我写出的程序依旧不能解决所有问题，而且现在会出现程序没执行完毕就停了，程序不报任何错误，好像结束了一样。

想赖咨询一下，大家有没有什么好的方法去匹配所有情况，因为网址拼接这块是个重点，如果不能有效拼接就无法抓取更多网址，但是通常的拼接不能解决所有情况。

希望大家给予指导。
