Welcome to WebmasterWorld Guest from 188.8.131.52
My predecessor has set-up an itunes compliant podcasting RSS feed that renders ok in Firefox without an XSLT file. This would seem to confirm that an XSLT file isn't a requirement to render rss in Firefox and IE7+.
However, I created a test news feed using feedforall, I saved this to my desktop and when I open it in the browser I just see the raw XML and a message which reads "This XML file does not appear to have any style information associated with it. The document tree is shown below."
I'm now totally confused. Do I need XSLT to render RSS in Firefox and IE7+ or not?
I'm very new to RSS so any advice would be very welcome.
ps here's code for the test news feed I created with feedforall -

Time: 6.30-8pm GMT<br>
Venue: Old Theatre, Old Building<br>
Speaker: Thomas L Friedman<br>
Chair: Professor Eric Neumayer<br />
Thomas L Friedman takes a fresh and provocative look at two of our biggest challenges – the global environmental crisis and America’s surprising loss of focus and national purpose since 9/11 – and shows how they’re linked. He argues that we need American commitment and leadership in a green revolution, a revolution that will be the biggest innovation project in history, one that will inspire us to summon all the intelligence, creativity, boldness and concern for the common good that are our greatest human resources.
Thomas L Friedman, the foreign affairs columnist for The New York Times, is a three-time Pulitzer Prize winner, and the author of From Beirut to Jerusalem, The Lexus and the Olive Tree, Longitudes and Attitudes and The World is Flat, winner of the first Financial Times/Goldman Sachs Business Book of the Year Award.</p></description>

[edit reason] Don't link to live feeds please [/edit]
Nearly all major browsers have support for XML and XSLT. That does not mean that they have RSS readers built in. Opera is the only major browser with a feed reader included. All other browsers require a plug-in or add-on.
The layout isn't particularly sophisticated and of course there are none of the features you would get with a dedicated feed reader but it renders ok in the browser with clickable links to media items or associated web pages etc as opposed what happened pre IE7 when I would just see the raw XML code.
Here's a screen grab of my itunes rss feed rendered in Firefox 3 without any additional plugins and without XMLT translation.

[edit reason] No links to examples, thanks [/edit]
The reason my test RSS news feed didn't render in my browser was due to the fact I was running it locally from my c drive. As soon as I uploaded it and accessed it via www it worked as I expected it would.
Therefore I can only conclude that RSS feeds do render in the latest Firefox and IE browsers. They don't have all the features of a dedicated RSS reader but they do render the feed with clickable links to media or associated web pages. As opposed to pre IE7 when all I would see would be the raw XML code.
I'm new to RSS so more than happy for someone to correct me if I'm wrong.
XSLT allows you to generally have some control over the look of a feed. This will work mostly with web browsers. However, most feed readers will ignore your formatting and use their own.
You can't predict where and how your feeds will be used so often a stylesheet is pointless. As you know most browsers will show a feed with their own style. Only Google Chrome shows me raw XML without an XSLT.
