Adding fields to be displayed with the RSS Reader 2.0

Have you navigated directly to the RSS feed manually? You might try to use an XML Datasource and a basic repeater. I think you might have better results.

When you say navigating directly to the RSS feed manually do you mean viewing the RSS feed in a browser? If so then yes I can. While the data in the tags are not visible on the page, when I view the source I can see them there.

Yes, in the browser. Can you send a snippet of what a record might look like. Depending on the data in the RSS you may have to use EvalCDATA("FieldName", false). Check out the help docs

Here's what the transformation looks like for the RSS feed:

<item>
 <guid isPermaLink="false"><%# Eval("NodeGUID") %></guid>
 <title><%# EvalCDATA("DocumentName") %></title>
 <description><%# EvalCDATA("NodeAliasPath") %></description>
 <pubDate><%# GetRSSDateTime(Eval("DocumentCreatedWhen")) %></pubDate>
 <link><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrlForFeed(), Eval("SiteName")) %>]]></link> 
<location><%# Eval("Location")%></location>
<organization><%# Eval("Organization")%></organization>
<province><%# Eval("Province")%></province>
</item>

Here's what it looks like when viewing the source of the feed feed i.e. http://albertacentral-old.dev/Alberta-Central-Careers/?item=Careers-at-Alberta-Central.

<?xml version="1.0" encoding="utf-8"?><rss version="2.0">
<channel>
<title><![CDATA[Careers at Alberta Central]]></title>
<link><![CDATA[http://albertacentral-old.dev/Alberta-Central-Careers/?item=Careers-at-Alberta
Central]]></link>
<description><![CDATA[A feed for jobs at Alberta Central]]></description>
<language><![CDATA[en-US]]></language>
<item>
<guid isPermaLink="false">837e4ac4-e065-493c-812e-3914f220ddec</guid>
<title><![CDATA[Business Loans Specialist]]></title>
 <description><![CDATA[/Alberta-Central-Careers/Business-Loans-Specialist]]></description>
 <pubDate>Mon, 13 Jan 2014 19:27:38 GMT</pubDate>
 <link><![CDATA[http://albertacentral-old.dev/Alberta-Central-Careers/Business-Loans-Specialist/?feed=Careers-at-Alberta-Central]]></link> 
<location>Calgary</location>
<organization>Credit Union Central of Alberta</organization>
<province>Alberta</province>
</item>
</channel>
</rss>

And here is the transformation for the RSS Reader on the site consuming the feed:

<h2><a href="<%# Eval("link") %>"> <%# Eval("title") %> </a></h2>
<!--<%# Eval("description") %>-->
<%# Eval("organization") %><%# Eval("location") %><%# Eval("province") %>

It's kind of odd because when I comment out the description and checked the data for the "organization" is now displaying but the locaation and province are not. But you can see above that there is data in it.

I ended up stepping through the code and saw there was an XSD that it was reading in. I added the xml for the new fields into there and got it working.
