how can i delete duplicate lines and the line itself from the same document?

[2.270]

lets say i have a combolist in a notepad++

if there are duplicated lines, i want to delete the duplicated + the original lines, is there any way to do that?

Make sure you click Regular expression.
 

Code:

 

 
[code]
^(.*?)$\s+?^(?=.*^\1$)

[/code]

EDIT:
Just saw that you wanted to delete both lines.... my bad ...

this method only deletes all the duplicates
