Regex 在单词Vs之前的每个字符更改后添加一个空行

使用TextFx工具，我删除了重复的行。
问题是：要将“Vs”之前的部分相同的行分组。 我想在更改后添加一个空行

范例

前一行：

- traveling by plane Vs By TGV train.
- travel by plane Vs By TGV train.
- traveling by Bike Vs By Cycle.
- travel With plane Vs By TGV train.
- traveling by Bike Vs By TGV train.
- traveling by Bike Vs By Cycle.
- traveling by Bike Vs By TGV.
- traveling by Car Vs By TGV train.
- traveling by Car Vs By Truck.
- traveling by Car Vs By Bike.
- traveling by Car Vs By TGV.

之后的行：

- traveling by plane Vs By TGV train.

- travel by plane Vs By TGV train.

- travel With plane Vs By TGV train.

- traveling by Bike Vs By TGV train.
- traveling by Bike Vs By TGV.
- traveling by Bike Vs By Cycle.

- traveling by Car Vs By TGV train.
- traveling by Car Vs By TGV.
- traveling by Car Vs By Truck.
- traveling by Car Vs By Bike.

我猜这就是你想要的-替换

^(.*?)\bVs\b(?!.*\s+\1).*

与

正则表达式首先匹配一行的开头，然后将

^

到单词Vs的所有内容捕获到组2中。匹配单词后，它使用一个否定的前瞻，确保下一行的开头与这一行不同（将任何内容与

*

行尾相匹配，将换行符与

\s+

相匹配，然后使用对捕获的行首的反向引用）。如果该负前瞻匹配（下一行与当前行的开始方式不同），则在当前行（新组）之后插入一个换行符是匹配的，因此我们最终匹配该行的其余部分

将匹配的行替换为自身（整个匹配-

$0

）加上一个换行符-

$0\n

.

我发现“角色的每一次变化”都有点不清楚/误导。从您的示例判断，您希望将“Vs”之前的部分相同的行分组？

$0\n
