Java正则表达式中的POSIX字符等价物 [英] POSIX character equivalents in Java regular expressions

问题描述

我想在Java中使用这样的正则表达式： [[= a =] [= e =] [= i =]] 。

I would like to use a regular expression like this in Java : [[=a=][=e=][=i=]].

但是Java不支持POSIX类 [= a =]，[= e =]等。

But Java doesn't support the POSIX classes [=a=], [=e=] etc.

我该怎么做？更确切地说，有没有办法不使用US-ASCII？

How can I do this? More precisely, is there a way to not use US-ASCII?

推荐答案

Java确实支持 posix角色类。语法不同，例如：

Java does support posix character classes. The syntax is just different, for instance:

\p{Lower}
\p{Upper}
\p{ASCII}
\p{Alpha}
\p{Digit}
\p{Alnum}
\p{Punct}
\p{Graph}
\p{Print}
\p{Blank}
\p{Cntrl}
\p{XDigit}
\p{Space}
