EDI 文件的正则表达式

Question

我有以下 EDI 文件，需要过滤元素 LOC+11 而不是 LOC+7，我需要它们之间的所有段，LOC 段重复但它们之间的段不重复。

目前我的正则表达式看起来像 LOC[^L]*(?:L(?!OC)[^L]*)* 但我得到了 4 个结果，因为它也过滤了 loc+7 元素。

我只需要 2 个结果。你能帮帮我吗？

Answer 1

您可以使用

LOC\+11[^L]*(?:L(?!OC\+11)[^L]*)*
LOC\+11[\w\W]*?(?=LOC\+11|$)

参见regex demo。

详情:

LOC\+11 - LOC+11 字符串
[^L]*(?:L(?!OC\+11)[^L]*)* - 直到第一次出现 LOC+11 子字符串的任何文本（使用）。

尽管使用上述两种模式得到的结果是相同的，但第一种模式要快得多，前提是没有太多 L 后面没有跟随 +11。
