EDI 文件上的正则表达式
Regex over EDI File
大家好，我有一个 EDI 文件，其中包含数量、交货日期等信息。
现在我想用正则表达式拆分它，这样我就可以用所需的信息拆分行。所以附上你找到文件内容。我用像 LIN+.* 或 LIN+.*? 这样的表达式试过了？但后来我只把所有的 LIN 段放在一起，或者把 LIN 段分开但信息较少。我想将每个 LIN 元素与其后的全部信息分开。
有人可以帮助我吗？

您可以使用
LIN(?:(?!LIN).)*
或者，更高效的版本（在 之后）：
LIN[^L]*(?:L(?!IN)[^L]*)*
见regex demo #1 and regex demo #2
(?:(?!LIN).)* 模式匹配任何不以 LIN 字符序列开始的字符 (.)，0 次或更多次，但尽可能多.
[^L]*(?:L(?!IN)[^L]*)* 模式匹配除 L 以外的任何 0 个或多个字符，然后出现 0 个或多个 L 序列，但后面没有跟 IN，然后L.
以外的 0+ 个字符
