问题描述

在记事本++中有删除每隔一行或第n行的方法吗?我有一个庞大的数据列表,我需要减小的大小。

Is there a way in Notepad++ to delete every other or nth line? I have a massive list of data and I need to reduce the size.

数据本身不是那么重要,从一个列表中的10,000项我只需要一个选择of 5,000

The data itself is not that important and out of a list of 10,000 items I only need a selection of 5,000

推荐答案

我认为这是一个奇怪的想法,尝试用Notepad ++,但我喜欢一个挑战,所以我决定

I think it's a strange idea to try to do with Notepad++, but I like a challenge, so I decided to give it a spin.

打开替换菜单,填写([^ \\\
] * \\\
)[^ \\\
] * \ n
,并在替换为框中输入 $ 1 然后为搜索模式选择正则表达式,单击全部替换,每隔一行删除。

Open the replace menu, fill in ([^\n]*\n)[^\n]*\n in the "Find what" box and $1 in the "Replace with" box. Then select regular expression for the search mode, click replace all and every second line is deleted.

如果你想做类似的事情,你可以构建类似的正则表达式。例如,(([^ \\\
] * \\\
){a})[^ \\\
] * \\\
将替换每第n行将替换为n-1和 [^ \\\
] * \\\
([^ \\\
] * \\\
) code>会让你保持偶数行,而不是奇数。

You can build similar regexes if you want to do something similar. For example, (([^\n]*\n){a})[^\n]*\n will replace every nth line if you replace a by n - 1 and [^\n]*\n([^\n]*\n) will let you keep even lines instead of odd ones.

(这并不困难 - 我只需要更新我的过时的记事本++安装。)

(That wasn't hard at all - all I had to do was update my outdated Notepad++ installation.)
