Repeated namespaces in media RSS

We wanted to add media thumbnails to our RSS feed. Once we added xmlns:media="http://search.yahoo.com/mrss/", that namespace appears as an attribute for every item in the feed. The hh and xalan namespaces don't do that. See attached files.

   Hi Michael,

   When you have a moment, try modifying the first line of your XSLT Format by changing the extension-element-prefixes="date-converter" attribute/value to:
   

   extension-element-prefixes="date-converter media"
   

   Let me know if that does the trick.

   Thanks

   But I don't have an `extension-element-prefixes="date-converter"`
   attribute/value
   in my XSLT format....

   Bah, sorry - I had switched to another Format in my instance and copied the wrong info. Try adding this attribute to your <xsl:stylesheet> element:
   

   extension-element-prefixes="media"

   No, that doesn't work. It removes the duplicate namespaces, but also
   removes the `media:thumbnail` node from the RSS feed.

   Can you attach your XML output prior to styling it? That will allow for me to play around with it to see if I can get something to work.

   Also, can you verify that this isn't actually causing any problems but that you're just looking for a way to remove those extra attributes?

   I knew I forgot something. See attached.

   No, this shouldn't actually cause any problems, but we've been surprised before. One of the systems which consume the feed is powered by https://www.apereo.org/projects/uportal

   Thanks for attaching that. Try adding this attribute to your <xsl:stylesheet> element:
   

   exclude-result-prefixes="media"
   

   I think those are the results you're looking for, but I'll wait to hear back.

   That's much better. The namespace is still repeated for each thumbnail, but the feed is certainly valid according to the W3C.

   Good deal. I've tried a few things to see if I can remove that namespace for the <media:thumbnail> element but haven't gotten anything to work yet. If I think of anything over the next few days I'll let you know, but otherwise it sounds like you're in good shape here with the additional exclude-result-prefixes attribute.

   Have a good one!
