Using diff with process substitution:

$ diff <(sed -n '/<Marker 1>/,/<Marker 2>/p' before.txt) <(sed -n '/<Marker 1>/,/<Marker 2>/p' after.txt)

Thanks, but how can i get only the content between the two markers, in the above case the markers also come in the output.

Hello,

You must just modify the 2 sed command like:

sed -n '/<Marker 1>/,/<Marker 2>/{/<Marker 1>\|<Marker 2>/!p}'
