如何删除||在记事本++上使用正则表达式从字符串末尾开始表达式？

Question

我有这样的字符串

न च <तुल्य-गुणः>K1  दूष्यः  न दोषः प्रकृतिः भवेत्|| 11 ||
उक्ताः  महाचतुष्पादे येषु आयत्तं <भिषक्-जितम्>T3|| 24 ||

我的目标是删除数字和 ||它们包含在字符串末尾的符号中。我尝试使用此表达式 \|\|[0-9.]+\|\| 但它仅适用于少数情况。我可以试试什么表情？请注意我是在 Notepad++ 上做的。

Answer 1

因为您只关心字符串的结尾，所以您需要使用 $

所以尝试：(\s*\|\| [\d]* \|\|)$ 并替换为空文本框。

点击后Replace All

Answer 2

使用

\|\|(?:\h+\d+\h+\|\|)+$

参见proof。
