I am trying to subscribe to an RSS feed for a fighter's history via MixedMartialArts.com, but this particular website updates the pubDate for each of the fights, causing duplicates every time the pubDate is updated.
http://www1.mixedmartialarts.com/?go=rss.fighterRecord&pid=8878384A5C892D13
However, other attributes of each remain the same, particularly <title>.
What can I do (maybe via Yahoo Pipes, or other normalizer) to fix this issue temporarily until they correct the problem on their end?
