RSS Transformation for Multiple Document Types

I am trying to create an RSS feed with the DocumentDataSource and the RSS Repeater. I created a DataSource that has Articles and my own custom data type Case Study which is similar to an Article. The problem is I need to make them look the same in an RSS field...so tried the following but I cannot get it to work right. Case Study has fields "CaseStudyName" which is the same as "ArticleName" in Article. I also have "TeaserText" which is the same as ArticleTeaserText. Short of naming the fields the same which i would like to avoid...how can I get this code to work?

<%@ Control Language="C#" AutoEventWireup="true" Inherits="CMS.Controls.CMSAbstractTransformation" %>
<%@ Register TagPrefix="cc1" Namespace="CMS.Controls" Assembly="CMS.Controls" %>
<item>
  <guid isPermaLink="false"><%# Eval("NodeGUID") %></guid>
  <title><%#IfEmpty(Eval("ArticleName"), <![CDATA[ Eval("CaseStudyName",false)]]>, <![CDATA[ Eval("ArticleName",false)]]>) %></title>
  <description><%#IfEmpty(Eval("ArticleTeaserText"),<![CDATA[ Eval("TeaserText",false)]]>, <![CDATA[ Eval("ArticleTeaserText",false)]]>) %></description>
  <pubDate><%# GetRSSDateTime(Eval("DocumentCreatedWhen")) %></pubDate>
  <link><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrlForFeed(), Eval("SiteName")) %>]]></link>
</item>

RE:RSS Transformation for Multiple Document Types

Hi,

could you please specify the settings of the DocumentsDataSource? Are you putting two classnames into it's Document types (classnames) property?

This could be a problem since the view that connects them into one table is not available by default, you may need to use QueryDataSource and connect it using SQL JOIN in custom query.

You could then check if the field is defined or empty for currently displayed record and render appropriate output.

Hope this will help.

Regards,
Zdenek

RE:RSS Transformation for Multiple Document Types

I solved it...I just forgot to post the fix. For those that might want to do what described above...here is my transformation for the RSS:

<item>
  <guid isPermaLink="false"><%# Eval("NodeGUID") %></guid>
  <title><![CDATA[<%# IfEmpty(Eval("ArticleName"), Eval("CaseStudyName", false), Eval("ArticleName", false)) %>]]></title>
  <description><![CDATA[<%# IfEmpty(Eval("ArticleTeaserText"), Eval("TeaserText", false), Eval("ArticleTeaserText", false)) %>]]></description>
  <pubDate><%# GetRSSDateTime(Eval("DocumentCreatedWhen")) %></pubDate>
  <link><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrlForFeed(), Eval("SiteName")) %>]]></link>
</item>
