一个或多个由空格分隔的单词的正则表达式 [英] Regex for one or more words separated by spaces

问题描述

我正在寻找一个正则表达式，其中我有一个或多个单词(可能还应该包括字母数字)，并用空格(一个或多个空格)分隔

I am looking for a regex where i have one or more words (possibly should cover alpha numeric also) separated by spaces (one or more spaces)

1. 测试这个东西"
2. 测试这个"
3. 测试"

以上是一些例子

我写了一个正则表达式来看看 #1 重复了什么

I wrote a regex to see what is repeating for #1

\s*[a-zA-Z]*\s*[a-zA-Z]*\s*[a-zA-Z]*\s*

所以我想为重复部分做一些类似 {3} 的事情.

so i wanted to do something like {3} for repeating section.

但它似乎不起作用..我不敢相信它这么难.

But it does not seem to work.. I cant believe it is this difficult.

(\s*[a-zA-Z]*){3}

推荐答案

如果你不在乎你有多少字，这会奏效:

If you do not care just how many words you have, this would work:

[\w\s]+

\w 是任何字母数字.如果您只需要字母，请将其替换为 a-zA-Z.

\w is any alphanumeric. Replace it with a-zA-Z if you need only letters.
