For any other twit who's interested, you can radically reduce the size of the
styleshhet for your Twitter feeds, and improve its appearance, by using a
variation on the following in your RSS web part.
<?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" />
<xsl:template match="rss/channel">
<style type="text/css">
.twit_title a {font-size: 1em; color: #111111}
.twit_date {color: #333333;font-style: italic;padding-left:8px}
.twit_list li {padding-bottom: 15px}
</style>
<ul class="twit_list">
<xsl:apply-templates select="item" />
</ul>
</xsl:template>
<xsl:template match="item">
<li><a target="_blank" href="{link}" class="twit_title"><xsl:value-of
select="description" disable-output-escaping="yes"/></a><span
class="twit_date"><xsl:value-of select="substring-before(pubDate,' +0000')"
/></span></li>
</xsl:template>
</xsl:stylesheet>

Actually, no. All I really needed to do was provide the full URL to the RSS
file. :*
That's what I love about this list: the ability to expose my idiotic errors to
a wide range of peers without feeling the slightest twinge of embarrassment. :D

Thanks Wampers. I was trying to connect to a Twitter feed. I did some more
testing with standard RSS and Atom feeds and they seem to work fine.
Maybe the feed is authenticated or the format is different?
In any case, it's opened up a whole new world with the discovery of the RSSBus
web part and then the free Twitter web part from the same site. :)

Hi Paul,
R u trying to connect to a corporate (intranet) feed? In that case you might
need to resort to Kerberos authentication or download the feed as an xml file
and feed on that.
Kind Regards,
Wilson Wampers

Subject: RSS WebPart exception
I'm getting an exception when applying changes to an RSS web part.
I figured it was down to ISA so changed the proxy settings in the web.config to
the following with no success.
<proxy usesystemdefault = "true" bypassonlocal="true" />
The exception is as follows. Any ideas??
RssWebPart: Exception handed to HandleRuntimeException.HandleException
