Is it possible to detect only the segments without the parentheses? I attempted to use this Regex but it didn’t work.

Source: “(([^()]+))”  
Target: -@1

Would you help me, please?  
Thanks a lot!

Hi!

I am not expert in Regex but I think when you want to use “-@1” in one field you should use “=1” in the other field.

But when I want to look for missing parentheses in target, I use this:  
Source: “\(.\*\)”  
Target: -“\(.\*\)”  
Search Mode: Regex

If you want to look for missing parentheses in source, just switch the codes.

I hope this can help you.

Best regards,  
Sílvia
