RegEx字符串可查找两个字符串并删除文件中的其余文本 [英] RegEx string to find two strings and delete the rest of the text in the file

问题描述

我需要使用记事本+++查找并删除文本文件中的其余部分 我想使用RegeX在thban上查找变体.....变量后面始终最多有5个字符(请参见圆点). 与我的搜索字符串，它撞到了最后一行，但整行.我只想保留这个词. 当这个工作的时候，我也想保留包含C3 .....的单词. tekst文件的其余部分可以删除. 还应该对大写不敏感

I need to do a find and delete the rest in a text file with notepad+++ i want tu use RegeX to find variations on thban..... the variable always has max 5 chars behind it(see dots). with my search string it hit the last line but the whole line. I just want the word preserved. When this works i also want keep the words containing C3..... The rest of a tekst file can be delete. It should also be caps insensitive

(?!thban\w+).*\r?\n?

\

THBANES900 and C3950 bla bla
THBAN
..THBANES901.. C3850 bla bla
THBANMP900
**..thbanes900..**

这应该导致

THBANES900 C3950
THBAN
THBANES901 C3850
THBANMP900
thbanes900

推荐答案

也许只是捕获那些令人感兴趣的单词，而不是替换其他所有单词?在Notepad ++中搜索模式:

Maybe just capture those words of interest instead of replacing everything else? In Notepad++ search for pattern:

^.*\b(thban\S{0,5})(?:.*(\sC3\w+))?.*$|.+

请参见在线演示

• ^-开始字符串ancor.
• .*\b-除换行符以外的任何字符，直到单词边界为止为零或多次.
• (-打开第一个捕获组.
  • thban\S{0,5}-匹配"thban"和零或5个非空白字符.
  • )-关闭第一个捕获组.
  • ^ - Start string ancor.
  • .*\b - Any character other than newline zero or more times upto a word-boundary.
  • (- Open 1st capture group.
    • thban\S{0,5} - Match "thban" and zero or 5 non-whitespace chars.
    • ) - Close 1st capture group.
    • .*-除换行符以外的其他任何字符，均为零或多次.
    • (-打开第二个捕获组.
      • \sC3\w+-一个空格字符，匹配"C3"和一个或多个单词字符.
      • )-关闭第二个捕获组.
      • .* - Any character other than newline zero or more times.
      • ( - Open 2nd capture group.
        • \sC3\w+ - A whitespace character, match "C3" and one ore more word characters.
        • ) - Close 2nd capture group.

        替换为:

        $1$2
        

        ---

        此后，您可能会得到空行，可以使用内置选项巧妙地删除该行.我不知道英文字词，因此制作了一个GIF，向您展示在哪里可以找到这些按钮:

        ---

        After this, you may end up with empty line you can switly remove using the build-in option. I'm unaware of the english terms so I made a GIF to show you where to find these buttons:

        我不确定忽略大小写的英文复选按钮是什么.但是请确保未选中该选项.

        I'm not sure what the english checkbutton is for ignore case. But make sure that is not ticked.
