我写了个即时聊天器，是用POST的，这是服务器返回来的聊天内容，我想单单把其中的聊天内容提取出来，一定要和服务器同步的，那边出现一个新的聊天内容后，软件里也会自动加上去，把聊天内容显示出来
例子  [129,"640262473","123.97.211.253","ddd","2012-2-31 10:32:24"]   其中ddd就是聊天内容，怎么提取出来，还有就是有新的聊天内容出现后，服务器数据返回来后，自动添加上去，前面和后面的内容都会变的哦，那个聊天内容不好提取。帮帮忙

不行哦，因为这个聊天记录会自动增加聊天内容啊，那能和服务器的聊天内容同步吗，前面和后面部分文字在变的

可以用正则提取啊

\[\d+,"\d+","\d+\.\d+\.\d+\.\d+","(\w+)","\d+\-\d+\-\d+\s\d+\:\d+\:\d+"\]

这个正则不是万能的哦，如果要匹配范围更广泛 还要做些修改才能使用

补充内容 (2012-3-31 14:47):
如果获取的数据都是规则的
"内容","2012-2-31 10:36:44" 这种格式，而且匹配空白内容那建议你使用这个正则
\"(\w*?)\",\"\d+\-\d+\-\d+\s\d+\:\d+\:\d+\"
