C#正则表达式问题 [英] C# regex question

问题描述

大家好，
我正在寻找一个正则表达式，以将反向地址从文本文件中拉出.

示例字符串:

"123这是一个示例字符串123234456567，并且该字符串不断前进123234456567，仍然不断前进789232111"

因此，从此我将需要2或3个单词+数字形式的任何内容.

正确的匹配项是:

匹配1:样本字符串123
匹配2:字符串继续前进123
比赛3:仍然进行789

我相信我可以将其用作正则表达式:

"^([a-zA-z] + | [a-zA-z] +/s + [a-zA-z] +)+/s + [0-9] $"

但是，仍然没有得到结果.有任何想法吗?

预先感谢，

Suraci.

我使用了此 [
So, from this I would need anything in the format 2 or 3 Words + Number.

Correct matches would be:

Match 1: sample string 123
Match 2: string keeps going 123
Match 3: and still going 789

I believe I am close by using this as my regular expression:

"^([a-zA-z]+|[a-zA-z]+/s+[a-zA-z]+)+/s+[0-9]$"

However, still not getting results. Any ideas?

Thanks in advance,

Suraci.

I used this[^] to build the expression, so you might want to tweak it a bit depending on the specific RegEx implementation (it works on the site I mentioned :) ):

(\s[a-zA-Z]+){3}\s[0-9]+

Or if {3} dosn''t work:

(\s[a-zA-Z]+\s[a-zA-Z]+\s[a-zA-Z]+)\s[0-9]+
