Hi, I'm trying to use the Mediawiki API to get information about revisions to a given page. I understand that it is possible to get the entire contents of a given revision. However I would like to know if it is possible to only get the diffs introduced in a given revision? This would result in a reduced bandwidth consumption. My goal is to get the most frequently used terms in a set of revisions to a given page. For instance, for the web page Wikipedia what were the most common terms in all revisions between 2007-09 and 2007-11. Thanks in advance for any comments on this issue, -- Sérgio Nunes
