使用TextFx工具我删除重复的行 问题：想要对“Vs”之前的部分相同的行进行分组。 我想在更改后添加一个空行。
示例
之前的行：
- 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.
后面的行：
- 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.
答案 0 :(得分：0)
我想这就是你所追求的 - 替换
^(.*?)\bVs\b(?!.*\s+\1).*
与
$0\n
正则表达式首先匹配行^的开头，然后将单词Vs的所有内容捕获到组2中。匹配单词后，它使用负面预测确保下一行的开头与此行的开头不同（将任何内容与.*的行尾匹配，将新行与\s+匹配，然后使用对所捕获的开头的反向引用这条线）。如果这个负面前瞻匹配（下一行不以当前的方式启动），我们有一个匹配，用于在当前后插入一个换行符（一个新的< em> group ），所以我们最终匹配线的其余部分。
用自己替换匹配的行（整个匹配 - $0）加换行符 - $0\n。
