Unfortunately Bloglines still
isn't handling xml:base attributes properly. My Atom feeds
have this on the div element which contains an article's
content, and it's set to the URL of the article, so
relative links in the article should work fine as they are. Bloglines
seems to use the root of the domain as the base instead.
Update (2006-11-10): This may actually be partly my fault, see below for details.
Since this is breaking things like blogging of photos for me, I've
temporarily added a call to the absolutify_links function
in the code which generates my Atom feeds. This will be in the next
version of Daizu. It makes all the links in the feed absolute, so
even the stupidest feed reader should get them right.
Update
So it looks like part of the problem was that I had the
xml:base attribute on the XHTML
div element, whereas the example given in the
Atom specification
puts it on the content element. According to the spec
xml:base is allowed on “any element defined by this
specification”. Since the div element is actually
defined as part of HTML that might not be included,
even though the Atom spec requires its presence. Of course there's
no reason why xml:base shouldn't be allowed there, but
it doesn't work that way in Bloglines or Google Reader.
I've moved xml:base to the content element,
and taken out the code to absolutify the links. The new version
does work in Google Reader, and apparently Bloglines will be rolling
out a fix that will make it work in the next week or so.
