I tried to search the solution in internet, but found nothing, is there anyone who can help me?

For my application, there is one document (Microsoft word), and this document is reviewed by several people in the "Track changes" mode, so the input to my application is the original document and the reviewed documents with changes (like insert/delete/comments).

By this link , I know how to extract all the changes from the reviewed documents.

what i want is to combine all the changes from all the reviewed documents into ONE document, and make all the changes "accepted", so the output of my application is one modified Microsoft document with all the changes (delete/insert/comment) accepted.

My problem is that I don't know how to combine the changes from several documents into one single document.

Anyone has an idea how to do this?

Thank you very much in advance.
