Given the following ; delimited string
a;; z
toy;d;hh
toy
;b;;jj
z;
d;23
d;23td
;;io;
b y;b;12
z
a;b;bb;;;34
z
和这个正则表达式
^(?!(?:(a|d))(?:;|$)).*(\s*\z|$)\R*
I am looking to get the full lines whose 1st. column is not a or d, and have the matching lines removed, like this
a;; z
d;23
d;23td
a;b;bb;;;34
Please see the demo
在演示中，“替换”面板中有第5个空行，我想删除该行。
I have used this \s*\z in this past for this purpose. As implemented here, it does not seem to work.
