英文:
What is the regular expression for matching everything except two specific strings?
问题
I want a regular expression to match everything but two strings, STRING1 and STRING2.
This is what I tried:
^(?!STRING1|STRING2).*$ is close, but it does not match STRING1X, which should be matched, because STRING1X is not equal to STRING1 and not equal to STRING2.
^(?!STRING1|STRING2)$ doesn't match anything.

^(?!STRING1$|STRING2$).*
解释：
^ 表示字符串的开头。
(?!STRING1$|STRING2$) 是一个负向前瞻断言，排除了精确匹配字符串 "STRING1" 和 "STRING2"。$ 锚点确保匹配包括整个字符串。
.* 匹配任意字符（除换行符外）零次或多次。
英文:
^(?!STRING1$|STRING2$).*
Explanation:
^ asserts the start of the string.
(?!STRING1$|STRING2$) is a negative lookahead assertion that excludes matches for the exact strings "STRING1" and "STRING2". The $ anchor ensures that the match includes the entire string.
.* matches any character (except newline) zero or more times.
