Regex: Find all lines that contain two identical words, and delete up to the second word

I have this 2 lines:

1. litere bebe litere oana stilou mancare acasa carte litere

2. litere bebe oana stilou mancare acasa carte litere

The word litere is repeated 3 times in the first line, and the same word is repeated 2 times in the second line. Also, the word stilouis present in both lines.

So, I want to find all lines that contain two identical words (litere), but delete up to the second word stilou

1 Answer

My solution is this one:

• Ctrl+H
• Find what: (litere)(?=.*\1).*(stilou)
• Replace with: LEAVE EMPTY
• check Wrap around
• check Regular expression
• DO NOT CHECK . matches newline
• Replace all

and if I want to keep the words litere and stilou, and delete everything bewteen them, I may use this regex:

• Ctrl+H
• Find what: (litere)(?=.*\1).*(stilou)
• Replace with: \1 \2
• check Wrap around
• check Regular expression
• DO NOT CHECK . matches newline
• Replace all
