group & access several lines

Hi there, I try to learn and improve my regex knowledge... I want to fetch all lines below the "="-line and between the "-"-lines and access them via $1 - $n. Is this possible? Or should I fetch the whole string below the "="-line and the last "-"-line, then seperate the lines after that in another...
