我有正则表达式将字符串拆分为单词，数字和标点符号列表。 如何制作列表中的“az”和“0-9”单个元素？

Question

It's looks so:

string[] lines = Regex.Split(line, @"\s+|(?!^)(?=\p{P})|(?<=\p{P})(?!$)");

It's split "ASds22d. asd ,156" to "ASds22d" + "." + "asd" + "," + "156" "ASds22d" + "." + "asd" + "," + "156" .

Here is problem with strings like "az", "0-9" or variations like "ac" and "4-5". My regex split "az 1-9" to "a" + "-" + "z" + "1" + "-" + "9" but i need just "az" + "1-9" .

Can someone fix this regex?

Answer 1

\s+|(?!^|-)(?=\p{P})|(?<=\p{P})(?<!-)(?!$)

You can try something like this.This will not split on - .If you have any examples where split on - is required it can OR ed again.

See demo.
