这里有哪位是正则的高手，有事请教

主要是要获取MEMO中规定MARK的MATCH的问题。

比如我用 \[TT\]((.|\n)*)\[\/TT\] 匹配字符，但是出现类似

[TT]AA[/TT]BB[TT]CC[/TT] 其匹配的结果是 AA[/TT]BB[TT]CC，该如何解决？

上面就是最好的证明

老朱，过来看一下，按正则的规矩来说是应该从左到右扫描字符的，现在怎么会出现跳过中间的MARK，读取头和尾之间的MATCH字符那？

是否我代码写错了？

这是我修改的动网的UBB的程序:

我在想，只要“不等于”（[^(\[\/TT\])]）掉 MATCH中得 [相关标签]就可以了是把？
但是好像不成功
