RSS Relative Links
Yeah, what he said!
I've invalidated my RSS feed by including relative URL references inside some of the IMG tags. Question: if I am required to include a LINK element in my RSS feed, is there a reason RSS aggregators can't use it to resolve relative links? The $REMOTE_HOST or equivalent? Given that people have been using relative URLs in pages for years, I'd expect RSS tools to be a bit more flexible in this regard. I mean, browsers can handle relative URIs, right?
Scott holds a lot more clout than I do in the web world - I'll be surprised if his post doesn't cause waves. He'll also show you how to parse your site's XML feed with CSS and the DOM.
