包含字母和数字以及可能包含下划线和破折号的任何字符串的正则表达式代码 [英] Regex code for any string containing BOTH letters AND digits and possibly underscores and dashes

问题描述

我的正则表达式知识非常有限，但我正在尝试编写/找到一个表达式来捕获文档中的以下字符串类型:

My regex knowledge is pretty limited, but I'm trying to write/find an expression that will capture the following string types in a document:

做匹配:

• ADY123
• AD12ADY
• 1HGER_2
• 145-DE-FR2
• 自行车1
• 2自行车
• 128D
• 128878P

不匹配:

• 自行车
• 183-329-193
• 3123123

这样的表达可能吗?基本上，它应该找到任何包含字母和数字的字符串，无论字符串是否包含破折号或下划线.我可以使用以下两个正则表达式找到前两个:

Is such an expression possible? Basically, it should find any string containing letters AND digits, regardless of whether the string contains a dash or underscore. I can find the first two using the following two regex:

• /([A-Z][0-9])w+/g
• /([0-9][A-Z)w+/g

但是搜索可能的破折号和连字符会使事情变得更加复杂...

But searching for possible dashes and hyphens makes it more complicated...

感谢您提供的任何帮助！:)

Thanks for any help you can provide! :)

更多信息:

我在以下方面取得了一些进展:([A-Z|a-z][0-9]+-*_*w+) 但它没有捕获包含多个连字符的字符串.

I've made slight progress with: ([A-Z|a-z][0-9]+-*_*w+) but it doesn't capture strings with more than one hyphen.

我有一个包含大量文本字符串和数字字符串的文档，我不想捕获它们.我想要的是任何产品代码，它可以是任何长度的字符串，带或不带连字符和下划线，但始终包含至少一个数字和至少一个字母.

I had a document with a lot of text strings and number strings, which I don't want to capture. What I do want is any product code, which could be any length string with or without hyphens and underscores but will always include at least one digit and at least one letter.

推荐答案

您可以在不区分大小写的模式下使用以下表达式:

You can use the following expression with the case-insensitive mode:

((?:[a-z]+S*d+|dS*[a-z]+)[a-zd_-]*)

说明:

                   # Assert position at a word boundary
(                    # Beginning of capturing group 1
  (?:                # Beginning of the non-capturing group
    [a-z]+S*d+     # Match letters followed by numbers
    |                # OR
    d+S*[a-z]+     # Match numbers followed by letters
  )                  # End of the group
  [a-zd_-]*         # Match letter, digit, '_', or '-' 0 or more times
)                    # End of capturing group 1
                   # Assert position at a word boundary
