正则表达式:如何匹配不仅仅是数字的字符串 [英] Regex: How to match a string that is not only numbers

问题描述

是否可以编写一个正则表达式来匹配所有不只包含数字的字符串?如果我们有这些字符串:

Is it possible to write a regular expression that matches all strings that does not only contain numbers? If we have these strings:

• abc
• a4c
• 4bc
• ab4
• 123

它应该首先匹配四个，而不是最后一个.我曾尝试在 RegexBuddy 中摆弄前瞻和其他东西，但我似乎无法弄清楚.

It should match the four first, but not the last one. I have tried fiddling around in RegexBuddy with lookaheads and stuff, but I can't seem to figure it out.

推荐答案

(?!^\d+$)^.+$

这表示先行查找不包含所有数字并匹配整行的行.

This says lookahead for lines that do not contain all digits and match the entire line.
