Now, that would seem to be a rather interesting trick without the -n
option to sed(1), as the default action is p, and an explicit p would
then double that output, e.g.:

$ echo 'AAA
> some text
> some text
> BBB' |
> sed '/AAA/,/BBB/p'
AAA
AAA
some text
some text
some text
some text
BBB
BBB

So, let's presume you meant something more like:
sed -ne '/AAA/,/BBB/p' <file>
gave you:
AAA
some text
some text
BBB
and want similar, but without the starting AAA and ending BBB lines.
sed -ne '/AAA/,/BBB/{;/AAA/n;:l;/BBB/d;p;n;bl;}'

ruby -ne'BEGIN{$a=[]};$a << $_ if ~/AAA/ .. ~/BBB/;END{puts $a
[1..-2]}' file
