I'm having trouble with datasources. Any idea what I'm doing wrong?

I'm working with using a datasource of an image RSS feed, but I can never get the images to appear. I've tried to distill the datasource gallery sample code to its bare essentials. Here's my code:




<wire>


    <datasources>  


        <datasource name="gallery" source="" query="//item" providertype="xml" parsenamespaces="yes"/>


    </datasources>


    <styles>


    </styles>


    <classes>


        <class name="image">


            <image name="[param:index]" height="100%" align="center" valign="center" contain="yes" source="[param:sourceMain]" _page="[param:index]" />


        </class>


    </classes>


    <main>


        <panel name="slides" alias="SLIDES" width="100%" height="100%">


            <list name="scroller" width="100%" height="100%" datasource="gallery" orientation="horizontal" paginate="yes" >


                <object class="image" index="[param:dataSourceIndex]" sourceMain="[param:url]"/>


            </list>


        </panel>


    </main>


    <actions>


        <action name="load" oninit="yes" >


            <assign property="datasource:gallery.source" value="http://widget.stagram.com/rss/n/thillsman" />


            <assign property="var:curPage" value="1"/>


        </action>


    </actions>


</wire>

The URLs for the images are located at rss/channel/item/url in this XML file: http://widget.stagram.com/rss/n/thill... but my code doesn't seem to find them. Any ideas?

It looks like your [param:url] is one level deeper than you think, it should be [param:image/url]. That should do the trick.

keep up the good work!

Hmm... that didn't work either. I tried [param:image/url] and [param:img/url]. The < img> tag that comes before the tag in the feed is never closed. So I tried downloading the XML file locally, deleting the < img> tags, uploading it to my app files, and setting it as my datasource value as a relative link. But that didn't seem to work either.

Do I have any options to force it to pull from the right place with parsenamespaces="no"?

Oh there is one more thing that you need to change. I am sorry. instead of "source" on your image tag, you need to change it to "url" since your image source is coming from a url.
