Hi,

I am looking for a bit of assistance with the Form and List module, I searched the forum but couldn't find a similar case.

We are using the Form and List module to display a music chart here http://www.theedge.co.nz/Music/Fat40.... and I would like to provide the contents of this table to a 3rd party as XML.

So I figured that the "Show All Data as XML" feature would allow us to do this as it clearly shows all the data we need to pass on to the 3rd party. However, I am finding that it only shows XML when logged in as an Administrator but not when as an Unathenticated user (I have provided more detail further down this post).

Is there any way around this? Do I need so set a particular permission or check box somewhere?

Your help is very much appreciated.

Kind Regards,
Tom Jackson

The Issue in More Detail
-------------------------------------------------------------

When visiting this XML URL http://www.theedge.co.nz/DesktopModul... when not logged in (ie as an Unathenticated user) there is no response from the server. These are the response headers to further demonstrate that.

However, when logged in as a Administrtator and I visit the XML URL it shows me the XML as expected this

Did you ever find a solution for this? I need to do the same for anonymous users.

XML is limited for security reasons to users with module edit permissions. You can combine XMl  module and formandlist datasource to deliver any custom xml based on a fnl module.

Stefan

Hi Jacques 

Apologies for the delayed reply, I have been experiencing difficulties logging back into dotnetnuke.com and usability issues on retrieving my password.

The solution I came to was fairly simple in the end. I created a normal ASP.NET .aspx page and used VB code in these to get the server to output the required XML from the UserDefinedTable / FormAndList module (and I removed nodes I didn't need in the process).

The .aspx file in created would be located at  http://www.domainname.com/portals/0/External/MusicChart/MusicChartName.aspx and has the following code in it.

<%@ Page Language="VB" ContentType="text/xml" ResponseEncoding="utf-8" %>
<%--<%@ OutputCache Duration="20" VaryByParam="none" %>--%>
<%-- 20 Second output cache, disable this when debugging --%>
<%@ Import namespace="System.IO" %>
<%@ Import namespace="System.Data" %>
<%@ Import Namespace="System.Xml" %>
<%@ Import Namespace="System.Xml.Xsl" %>
<%@ Import Namespace="System.Xml.XPath" %>
<%@ Import Namespace="DotNetNuke.Entities.Users" %>
<%@ Import Namespace="DotNetNuke.Modules.UserDefinedTable" %>
