正则表达式匹配一个不是空格的单个字符 [英] regex to match a single character that is anything but a space

问题描述

我需要匹配一个不是空格的单个字符，但我不知道如何使用正则表达式来做到这一点.

I need to match a single character that is anything but a space but I don't know how to do that with regex.

推荐答案

以下内容就足够了:

[^ ]

如果您想将其扩展为除空格之外的任何内容(换行符、制表符、空格、硬空格):

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

或

\S  # Note this is a CAPITAL 'S'!
