hi Domenico
no, you need the importNode() thing, otherwise FF3 (all kinds: alpha and
beta and definitive) will not append your content. it doesn't harm FF2
because FF2 already supports this method. i expect opera to do it too.
your loop through the imported XML isn't needed because you don't
necessarily need an <svg>-element, you can also import fragments (they
just need to be consistent, closed elements and so on)
my question was about the xmlRequest.status. in an html environment it
shows 200, in local environment only 0. how to handle this in mixed
environments?
