Hello, 
I have a transformation that looks like this:
<%@ Register Src="~/CMSWebParts/Viewers/Documents/cmsrepeater.ascx" TagName="repeater" TagPrefix="uc1" %>
<item>
  <guid isPermaLink="false"><%# Eval("NodeGUID") %></guid>
  <title><![CDATA[<%# Eval("DocumentName") %>]]></title>
  <categoryid><%# Eval("newscategoryid") %></categoryid>
  <smalldescription><![CDATA[<%# Eval("smalldescription") %>]]></smalldescription>
<mainText><![CDATA[<%# Eval("mainText") %>]]></mainText>
<photo><![CDATA[<%#  GetFileUrl("carouselNews_130x100") %>]]></photo>
  <pubDate><%# FormatDateTime(Eval("DocumentLastPublished"), "yyyy-MM-dd HH:mm:ss") %></pubDate>
  <link><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrlForFeed(), Eval("SiteName")) %>]]></link>
<DocumentWorkflowStepID><%# Eval("DocumentWorkflowStepID") %></DocumentWorkflowStepID>
<rtmp><%# Eval("rtmp") %></rtmp>
<current><%# Eval("NodeAliasPath") %></current>
<uc1:repeater runat="server" ID="ShowRelatedVideo" ClassNames="Site.video" TransformationName="Site.Video.VideoForRSS" Path= Eval("NodeAliasPath")  SelectOnlyPublished="true" HideControlForZeroRows="true" EnableViewState="false" />
</item>
On the bottom I am trying to display some elements that are under the
document used on the transformation. I want to alter the
Path=Eval("NodeAliasPath") to something that gets the documents under
it. So, I need something like that Path=Eval("NodeAliasPath")/%
How can I do it?
Any help is appreciated. 
Thank you,
Dimitris
