So if you diff xml docs, will users be expected to read the raw xml diff output? Or, is there enough documentation on the file formats available so that when you diff two Word docs, for example, that you can create a third doc using Word's "show revisions" feature?
hey derek, Leo here -- I'm CTO at kivo. So, although the PowerPoint COM API is super old and buggy, the OpenXML standard which has been around since Office 2007 is actually pretty advanced. This means that you can realistically diff two versions of a file and extract and analyze the changes. The C# wrapper for this is also good (the hard bit is actually serializing the slide from COM -> OpenXML in memory). We would never expect our users to read the XML!
