正則表達式匹配spcific目錄路徑，但不是其他人

Question

我有一個文件包含很多行。

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:/ 

我要的是隻匹配以下行：

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

請幫我想出正則表達式，將實現上述場景。

Answer 1

This regex將只捕捉你想要的路徑，並使用negative lookahead如果有後子目錄home/

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