in reply to regex and delete

bla ...

depending on your textfile this can be indefinitely complex.

are parens ever nested?

is it always (L \d+ W \d+)?

If it's not a fix format I would try to match every parens-pair, and call a function with the match with /e modifier. s/\(.*?\)/kill_LW($&)/ge

    It's a fix format and it's working now. Thank you for your solution, May be I'll try this some other time.

      no it's not, chorobas solution will delete any "L " outside of parens too.

      if its really a fix format, use something like s/\(L (\d+) W (\d+)\)/($1 $2)/g
