我们如何使用正则表达式删除或过滤数据以在中间删除数据？起点是第一个日期（日期可以是动态的，它不是固定的），例如 08/03/2020，终点是大写字母字符串中的最后 3 个（这也是动态的，但大写字母最多只能包含 3 个字符) 例如下面字符串中的 TRU。并且应该在此之后忽略或删除所有数据

这是我当前的正则表达式：

Regex.Match(text,"(?<=08/03/2020\s+)[\S\s]*?(?=TRU)").Value.Trim

但它不是动态的。

这将被删除，因为这已经在 08/03/2020 和 TRU 之后。

知道我们如何为这个设计一个正则表达式吗？谢谢你。#要删除的数据

您可以使用

(?ms)\A(?:\d{2}/\d{2}/\d{2}(?:\d{2})?|−−DATE−−)\s.*\s\p{Lu}{3}$

查看正则表达式演示

细节

  • (?ms)- RegexOptions.Multiline（现在^匹配行开始和$行结束位置）和RegexOptions.Singleline（.现在也匹配换行符）内联修饰符
  • \A- 字符串的开头
  • (?:\d{2}/\d{2}/\d{2}(?:\d{2})?|−−DATE−−)- 两位数, /, 两位数,/两位或四位数字或−−DATE−−字符串
  • \s- 一个空格
  • .*- 任何零个或多个字符，尽可能多
  • \s - 一个空格
  • [A-Z]{3}- 三个大写 ASCII 字母（\p{Lu}{3}匹配任何语言的三个大写字母）
  • $- 行尾。
