你确定一个句子结束然后检查那个角色

顺序，你希望有人不会把一个放在一个

句子的中间，以免你得到不正确的结果，因为博士不会结束一个

的句子，但它会似乎是因为。< space>可能是一个好的

一个句子结尾的指标，但是，那你怎么建议用一个我刚刚输入的那个非常极端的句子来处理



很长但没有技术句子结束标点符号，尽管任何

试图确定句子结束会（或应该）找到它们。


!?。然后是一个空间。 RegEx的好工作除了方法中固有的

缺陷。

You determine what ends a sentence and then you check for that character
sequence, and you hope that someone does not put one in the middle of a
sentence lest you get incorrect results as a Dr. would not end a
sentence but it would appear to be since a .<space> might be a good
indicator of a sentence ending, but then, how would you propose to deal
with run-on sentences such as the one I just typed that is extremely
long but has no technical sentence ending punctuation in it although any
attempt to determine a sentence end would (or should) find them.

!?. followed by a space. Good job for a RegEx except for the inherent
flaw in the approach.

这取决于你如何定义一个句子，不是吗？


有些人可能会说要计算。 ;人物，但是可以扔给你

关闭几个...也许很多!!


当然，你不能算数人们使用标点符号

一直

That depends on how you define a sentence, doesn''t it???

Some might say to count "." characters, but that can throw you
off by a few ... maybe a lot!!

And, of course, you can''t count on people to use punctuation
consistently

感谢您的建议。我认为这不是一个完美的检查，但有些

将是必要的基线。我已经到位检查

" return"但我怎么做一个正则表达式检查1？。。让我们说b / b
说5次？


再次感谢。

Randy

Thanks for the suggestion,. Its not a perfect check I guess but some
would be necessary as a baseline. I already have in place check for
"returns" but how do i do a regular expression checking for "1?.".Lets
say 5 times?

Thanks again.
