正则表达式-找到正确的模式 [英] Regular Expression - Finding the proper pattern

问题描述

我有一个基于正则表达式模式验证字符串(邮件主题行)的系统.

我提供-输入字符串和模式，它验证是或否.

我无法访问执行此操作的代码(或更糟糕的是，我什至不知道它所编码的是什么).只是正则表达式模式！

情况1:

Hi,

I''ve a system which validates a string (a mail subject line) based on a regular expression pattern.

I provide - Input string and Pattern and it validates yes or no.

I''ve NO ACCESS to code which does that (or worse, I don''t even know what it''s coded upon). Just the Regular Expression pattern!

Case 1:

Input: FW: 12334-123-412 my-name test mail
Pattern: \bmy-name\b
Validation: Successful

情况2:

Case 2:

Input: FW: 12334-123-412 my-name test mail
Pattern: \bMy-name\b
Validation: Failed

我需要使其不区分大小写，因此我尝试了模式(?i)(\ bmy-name \ b)

I need to make it case insensitive, hence I tried the pattern (?i)(\bmy-name\b)

Input: FW: 12334-123-412 my-name test mail
Pattern: (?i)(\bMy-name\b)
Validation: Failed

您可以在不了解比较代码的情况下以正确的模式帮助我吗?
还是给我一套可能用于测试的模式?

Can you help me with the proper pattern, having no knowledge of the comparison code?
or give me a set of possible patterns that I might use to test out?

推荐答案

尝试使用此

Try this

强力?

Brute force?

\b[Mm][Yy]-[Nn][Aa][Mm][Ee]\b
