正则表达式 - 获取第一部分和最后一部分

Question

有没有办法获取下面几行的第一部分和最后一部分？我猜正则表达式是要走的路。最好用notepad++

这不需要超级优化或任何东西。它偶尔会手动执行，如果运行几分钟，那很好。

如果在同一个正则表达式中同时处理 'TimeingLog' 和 'HandleArticleWarningOnOrder' 行是个大问题，我可以运行两个不同的正则表达式并合并结果。

我首先使用这个正则表达式来查找这些行，它们来自一个更大的列表，其中有很多我不感兴趣的行。 ^.{26}(HandleArticleWarningOnOrder -> -1.*|Timinglog.*)

请注意，线条可以比下面的示例更长或更短

Answer 1

您可以为您的特定匹配使用带有分支重置组的替换：

^(.{26})(?|(HandleArticleWarningOnOrder ->)\h{2,}-1\b|(TimingLog ->)).*('\d+')

模式匹配：

^ 字符串开头
(.{26})捕获第1组，匹配26个字符（你可以考虑让这个模式更具体一点）
(?|分支重置组
- (HandleArticleWarningOnOrder ->)\h{2,}-1\b 捕获 组 2 中的文本，然后匹配 2 个或更多空格和 -1 以及单词边界以防止部分单词匹配
- | 或
- (TimingLog ->) 捕获第2组，字面匹配
)关闭分支重置组
.* 匹配行的其余部分
('\d+') 捕获 组 3

Regex demo

在替换中使用捕获组 1、2 和 3，如

也许使用 \K 和单个捕获组的更简单的模式：

^.{26}(?:HandleArticleWarningOnOrder ->(?=\h{2,}-1\b)|TimingLog ->)\K.*('\d+')

在替换中使用

Answer 2

您可以使用此正则表达式替换字符串。

^(.*->)( *(-)?\d*(\.)?\d*: ('\d{1,}\'))*$

Regex Demo

并替换为 $1$5，捕获第 1 组和第 5 组。

Answer 3

这是给定示例的简短代码...

查找：^(\d.*->).*('\d+')
