Does it have to be sed? When I read your requirement, I immediately
thought about the EXAMPLES section in "man awk", where you'll find:
/start/, /stop/
Print all lines between start/stop pairs.
You could try this first:
awk -f '/foo/, /bar/' < input.txt > output.txt
Not verified, though.

If this works in GNU sed, you can install it (textproc/gsed) and
the use this command.
