IF i did get this straight, you want to extract the date and "Ende" from the last line.. so I'd extract it with
which goes for 2 digits dot 2 digits dot 4 digits any number of spaces followed by any number of = followed by any number os spaces again followed by Ende
In the end you can capture the date and "ende" separately with $1 and $2, while discarding the:
" ============ " in between.
