正則運算式在多行文本中獲取@和@之間的所有內容

我希望你沒事。

例如，我有一個帶有標簽@tag 的文本，我想將標簽之間的所有文本作為部分獲取（不是一個，請查看最后的圖片，在頂部，結果是 4 個匹配項而不是一個匹配項）。問題出在每個標簽的文本中，可能包含符號@，這將減少我的結果匹配。

我用不同的正則運算式嘗試了幾次，但都沒有成功

我使用的最終正則運算式是：

((^(@))|[^\"]@)[^(@)] \}\n

示例centent文本（我用于嘗試）：

這是圖片顯示我的問題

我想獲得@tag1 和@tag2,3,4...之間的整個部分，如果符號@ 在標簽的內容中，我該如何處理它？

uj5u.com熱心網友回復：

我不太確定[^\"]@在你的表達中使用了...它的目的是什么？你能舉個例子嗎？

無論如何，您必須從排除字串列中洗掉 @。并改變您的外觀在您的部分結束時。嘗試：

^@[^(] ?\}\n(?=\@|$)

• ^@ 匹配行首的@
• [^(] ?匹配任何期望(一次或多次的字符，直到（?使它變得懶惰）下一個元素的下一次出現...
• \}\n 您的段總是以大括號結尾，后跟新行
• (?=\@|$)關鍵部分：前瞻，確保以下元素是@（新段）或檔案末尾，而不捕獲它。這樣您就不會在結束之前剪切一個片段，您仍然可以捕捉下一個片段的開頭。

嘗試演示

uj5u.com熱心網友回復：

用

(?m)^@. (?:\n. )*

請參閱正則運算式證明。
