Status: RESOLVED INVALID

(Firefox :: Bookmarks & History, defect)

The following RSS 1.0 feed is valid but will not load into Firefox Live
Bookmarks. When I remove the empty xmlns attributes in the channel and item
elements, it works.

Reproducible: Always

Steps to Reproduce:
1. Save the above feed as file on a web server
2. Make a new Live Bookmark pointing to that feed
Actual Results:  
The Live Bookmark I created did not load the feed items even though the feed is
valid.

Expected Results:  
Loaded the feed correctly.

While you are correct that that feed is currently feedvalidator.org-valid, it
isn't valid against any of the RSS specs, and I'm filing a bug against the
feedvalidator hoping that soon it won't validate there, either.

If your root element is rdf:RDF, then you are either publishing RSS 1.0 or 0.90
(or 1.1 which we don't currently support). So, we look for a channel element in
the RSS 1.0 namespace, and if we don't find one we look for a channel element in
the RSS 0.90 namespace, and if we don't find one then as far as we're concerned,
the feed is empty. You don't have a channel element in either namespace, since
you reset the default namespace to the empty namespace - you have something that
could be approximately an RSS 0.91-2.0 channel element if it didn't have that
invalid-for-them items element.

I don't know why you are including that xmlns="" on your channel and item, but
that is what it means: "for this element, and all its children until it is
redefined, the namespace for elements without a prefix is ""." Since we have
absolutely no idea about the intended semantics of either a channel or an item
in no namespace inside an rdf:RDF element, all we can do is see it as a
completely empty feed.

I've made a fix to the feedvalidator in cvs.  The fix should go online later today.

sorry for bugspam, long-overdue mass reassign of ancient QA contact bugs, filter on "beltznerLovesGoats" to get rid of this mass change
