Compare Merge Viewer Example: Merging Word Documents
I just finished writing up a Wiki article describing how to implement a custom (i.e. non-text based) compare merge viewer. The example I used was a Word document comparison. Hopefully I'll be able to get the code into the Eclipse 3.5 stream once floodgates open for 3.5 development but, in the meantime, there's a link in the article from which you can download the bundle (it's a fragment of the org.eclipse.compare plug-in). The code is compatible with 3.3 and 3.4 so if you are interested in either seeing how to implement a custom compare merge viewer or you want to try out the Word document compare viewer, check out the article.
