处置获取到的大量html数据

dom html simple

处理获取到的大量html数据
获取到一大堆的html数据,大概有3万个字符的大小。但是前面没用的,只有后面几千字符是有用的,想从里面提取数据。如果直接用正则去处理就浪费了很多资源,有没有什么方法可以从字符串的最后面开始正则,然后取到某个地方就停止。
刚刚一开始尝试用simple_html_dom类来处理,但是后来卡住了...
因为每次去到的东西都不一定长短,所以直接截取固定数量的长度的字符这个方法不太好。

------解决思路----------------------
既然你并不能准确的你需要的内容从什么位置开始,那么就不存在资源浪费的问题
------解决思路----------------------
获取html
file_get_contents
curl

正则解析html,可以获取想要的文本。
------解决思路----------------------
没什么好办法,因为你要过滤数据,要么正则匹配,要么用你用的那个类。
