同样,我有很多块。我只需要一个图像 URL(文件后面紧接着许多图像 URL),第一个图像 URL 最好。这意味着,我需要如下所示的输出

答案1

在 notepad++ 中查找替换对话框:

  • 寻找:
    (\[img\].+\n)(\[img\].+\n)*
  • 替换为:
    $1
  • 检查“正则表达式”
  • 点击“全部替换”

你可以测试一下这里

答案2

以下是一种方法:

  • Ctrl+H
  • 找什么:^(\[img\].+\R)(?1)*
  • 用。。。来代替:$1
  • Replace all

解释:

^           : begining of line
(           : start group 1
  \[img\]   : literally [img]
  .+        : 1 or more any character but newline
  \R        : any kind of linebreak (\r, \n, \r\n)
)           : end group 1
(?1)*       : same pattern that the one is defined in group 1, 0 or more times

请勿检查. matches newline

替代品:

$1          : content of group 1

给定示例的结果:
