"Labels" in blogspot feeds.

Hi,

Blogger allows you to set tags (which it calls labels), and
even lets
you view a page of posts with just that label, but it
doesn't provide a
feed of that page.  Would it makes sense to have
planetplanet parse this
category out of the main feed and prepare the category-only
feed itself?
Is there a better way to achieve category-only blogger
feeds?

Thanks!

- Chris.

Here's an example of getting a label feed out of blogger:

To do category filtering, we'd have to add category to the
list of elements
that filtering works on. In Planet 2.0, that's not amazingly
simple because
it ignores them (because they're not a single value such as
"title"). Venus
might be able to do it already, but if not, it will most
likely be a simple
change to make.

But now you know that you can get label feeds out of
blogger.

Obviously, either Planet 2.0 or Venus can subscribe to a
category feed.

In Venus, the category information is retained, and can be
used to 
create custom feeds.  Atom feeds are created with XSLT
transformations, 
and the atom.xml.xslt has examples of stripping certain
elements.  This 
can be generalized to stripping out entire entries.  For
example, copy 
atom.xml.xslt to australia.atom.xslt, and add the following
lines to the 
latter:

<xsl:template match="
   atom:entry[count(//atom:category[term='austrailia']=0)]
"/>

What this does is match any entry which has zero category
elements with 
a term attribute with a value of australia.  Since this
template is 
empty (ends with "/>"), anything that is
matched is replaced with nothing.

Are the very simple 'filter' and 'exclude' parameters
working in Venus?
Which elements are they applied to?
