问题描述

所有在这里的正则表达式大师都好，我知道您在解决我的问题方面有很多工作要做.呵呵

hi to all regex master out there, I know you have a work around with regards to my problem. hehe

02-May-2011

或

22-May-2011

或

2-May-2011

(dd-MMM-yyyy)yyyy不接受数字以外的任何其他字符

(dd-MMM-yyyy) with yyyy not accepting any other characters than digit

推荐答案

[0-9]{1,2}/[a-zA-Z]{3}/[0-9]{4}

假设月份是3个字母的版本:例如1月，2月，3月.

That's assuming that the month is a 3-letter version: eg, Jan, Feb, Mar.

更新版本以匹配对问题的更改:

Updated version to match the changes to the question:

[0-9]{1,2}-[a-zA-Z]{3}-[0-9]{4}

如前所述，它实际上不会验证日期，它只会验证字符串是否匹配以下格式: 1或2个数字，破折号，3个字母，破折号，4个数字.

As has been mentioned, this won't actually validate the date, it'll just validate that the string matches the format of: 1 or 2 numbers, a dash, 3 letters, a dash, 4 numbers.
