Basically it works like this:
while[lines left][
take the first line in the left text.
find it in the right text.
either found [
collect it and all following same lines.
save it somewhere and remove both blocks.
][
collect lines until you find one in the right text
save them somewhere
]
]
do something usefull with the collected blocks.
