RegEx查找任何以大写字母为后跟冒号的单词

时间:2022-11-28 03:34:52

I need a RegEx to match an uppercase string ending with a colon. The string can contain spaces, numbers and periods. So that if:

我需要一个RegEx来匹配以冒号结尾的大写字符串。字符串可以包含空格、数字和句点。所以,如果:

mystring = "I have a C. GRAY CAT2:"

I want the coldfusion expression

我想要coldfusion表达式。

REFind("[A-Z0-9. ][:]",mystring) 

to return the number 9, matching "C. GRAY CAT2:". Instead, it is returning the number 21, matching only the colon. I hope that a correction of the regex will solve the problem. Of course I have tried many, many things. Thank you!

返回数字9,匹配“C. GRAY CAT2:”。相反,它返回的是第21号,只匹配冒号。我希望regex的修正能够解决这个问题。当然,我尝试过很多很多东西。谢谢你!

Details

细节

  • [A-Z0-9] - an uppercase letter or digit (in case the first char can be a digit, else remove 0-9)
  • [a - z0 -9] -大写字母或数字(如果第一个字符可以是数字,则删除0-9)
  • [A-Z0-9. ]* - zero or more uppercase letters/digits, . or space
  • [A-Z0-9。- 0或更多的大写字母/数字。或空间
  • : - a colon.
  • :-一个冒号。

To avoid matching 345: like substrings but still allow 23 VAL: like ones, use

要避免匹配345:就像子字符串一样,但仍然允许23 VAL: like ones, use。

\b(?=[0-9. ]*[A-Z])[A-Z0-9][A-Z0-9. ]*:

See this regex demo. Here, \b(?=[0-9. ]*[A-Z]) matches a word boundary first, and then the positive lookahead (?=[0-9. ]*[A-Z]) makes sure there is an uppercase letter after 0+ digits, spaces or dots.

看到这个正则表达式演示。在这里,\ b(? =[0 - 9。[a - z])首先匹配一个词的边界,然后是正的前视(?=[0-9]。[A-Z])确保在0+数字、空格或点之后有一个大写字母。

If you do not expect numbers at the start of the sequence, i.e. out of I have a 22 C. GRAY CAT2:, you need to extract C. GRAY CAT2, use Sebastian's suggestion (demo).

如果你不希望数字出现在序列的开始,例如我有一个22 C. GRAY CAT2:,你需要提取C. GRAY CAT2,使用Sebastian的建议(demo)。

Have revised the selected answer to my own question to cover the German special characters.

将选定的答案修改为我自己的问题,以覆盖德国的特殊字符。

[A-Z][A-Z0-9.ÜÄÖß ]*:

This appears to work, however the Germans have recently added a capital ß to their alphabet, which is surely not on most keyboards yet, and therefore will not be a problem for the RegEx for a while.

这似乎工作,然而德国最近增加了一个资本ß字母,这肯定不是大多数键盘,因此将不会是一个问题的正则表达式。
