Aaaaagh! Exactly, shame on me that I didn’t think about that.
After all, I’m a real newbie regarding regexp’s,
Only problem, I use bot the first (newline OR space) and the last (newline OR space) in the replacement as 1 and 3 , that means the ?= will NOT assign the following newline or space to 3 ?

so with the replacement line of 12 je3 3 will be empty even if there IS a space or newline after “je”, am I right ?

Thanks for the help!
