正则表达式匹配spcific目录路径，但不是其他人

Question

我有一个文件包含很多行。

例如：

HomeFolder=file:/user/local/home/joe/ 
HomeFolder=file:/user/local/home/max/ 
HomeFolder=file:/user/local/home/ted/ 
HomeFolder=file:/user/local/home/ 
HomeFolder=file:/user/local/ 
HomeFolder=file:/user/ 
HomeFolder=file:/ 

我要的是只匹配以下行：

HomeFolder=file:/user/local/home/ 
HomeFolder=file:/user/local/ 
HomeFolder=file:/user/ 
HomeFolder=file:/ 

请帮我想出正则表达式，将实现上述场景。

Answer 1

This regex将只捕捉你想要的路径，并使用negative lookahead如果有后子目录home/

^(HomeFolder=file:\/(?:user\/(?:local\/(?:home\/)?)?)?)(?!\w+\/)
