如何修剪网址列表到第一个文件夹

Question

我想将网址列表修剪为第一个文件夹

for example:
url.com/folder1/xxx/index.html
url.com/folder2/
url.com/folder3/xxx/yyyy/index.html
url.com/folder4/zzz/aaa/bbb/index.html

Output should look like this:
url.com/folder1/
url.com/folder2/
url.com/folder3/
url.com/folder4/

非常感谢任何帮助。 谢谢！

查找： ^.*?\/.*?\/\K.*$

Answer 2

查找内容：

^([^/]*/[^/]*/).*

或

必要时逃避正斜杠。

^([^\/]*\/[^\/]*\/).*

替换为：
