如何使用正则表达式在两位数之后接受空格 [英] How to Accept space after two digits using Regular expression

问题描述

任何人都可以建议我如何使用正则表达式进行轰鸣声格式。

68 10 19 22



i我试图使用

来实现上述格式^ [0-9] {2} [] {1} {0-9} {2} [] {1} {0 -9} {2} [] {1} {0-9} {2} $这个表达式但它不起作用。

先谢谢你。

解决方案

这个表达但它不起作用。

先谢谢。

一个非常简单的方法是：

 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 

请看我对这个问题的评论。问题没有完全定义，但是，如果你注意这个元素，你很可能会解决这个简单的问题：\ s（空白空间）。



另一个错误： {0-9} （背后有什么想法？： - ））你需要的地方 [0-9] 。



你需要学习如何使用我自己一起做这么简单的事情。我花了几秒钟修理它，但请自己动手。

Hi,
can any one suggest me how to do bellow format using regular expression.
68 10 19 22

i am trying to implement above format using
"^[0-9]{2}[ ]{1}{0-9}{2}[ ]{1}{0-9}{2}[ ]{1}{0-9}{2}$" this expression but its not working.
Thanks in Advance.

解决方案

" this expression but its not working.
Thanks in Advance.

A very simple way is :

\d\d\s\d\d\s\d\d\s\d\d

Please see my comment to the question. The problem is not fully defined, but, most likely, you will solve this simple problem if you pay attention for this element: \s (blank space).

Another mistake: {0-9} (what was the idea behind that? :-)) where you need [0-9].

You need to learn how to compose such simple things all by yourself. It took me few seconds to fix it, but please do it yourself.
