我有以下 EDI 檔案，需要過濾元素 LOC 11 而不是 LOC 7，我需要它們之間的所有段，即 LOC 段重復但它們之間的段不重復。
目前我的正則運算式看起來像LOC[^L]*(?:L(?!OC)[^L]*)*，但我得到 4 個結果，因為它也過濾了 loc 7 元素。
我只需要2個結果。你可以幫幫我嗎？

uj5u.com熱心網友回復：
您可以使用
LOC\ 11[^L]*(?:L(?!OC\ 11)[^L]*)*
LOC\ 11[\w\W]*?(?=LOC\ 11|$)
請參閱正則運算式演示。
詳情：
LOC\ 11-LOC 11字串[^L]*(?:L(?!OC\ 11)[^L]*)*- 直到第一次出現LOC 11子字串的任何文本（使用展開回圈原則）。
盡管使用上述兩種模式得到的結果是相同的，但第一種模式要快得多，前提是沒有太多L的 s 沒有跟在后面 11。
