I have the following XML retrieved from twitter:

I have tried using ListItemComponents to display the tweet text to no avail:

 

ListView 
{
    objectName: "twitterLSTVW"
    verticalAlignment: VerticalAlignment.Center
    horizontalAlignment: HorizontalAlignment.Center

    layout: FlowListLayout {}
    dataModel: XmlDataModel {source: "model.xml"}
            	    
    listItemComponents: [
			 ListItemComponent
                         {
			     type: "status"
					 
			     Container
                             {
			       id: item 
			       Label { text: ListItem.text.data }
			     }
                         }
		         ]
                 
 }

 

I have tried looking for examples but all of them include models that just use attributes and are not really nested.

 

If someone could please provide me with the right code to the listItemComponents.

 

Thanks!

Maybe it can only support for the tag with attributes. Like this one:

<root>    
    <item title="BlackBerry Dev" 	feedlink="http://feeds.feedburner.com/blackberry/CAxx?format=xml"/>
    <item title="Open BB News" 		feedlink="http://openbbnews.wordpress.com/feed/"/>
 </root>

 Your provided XML format is different. You can have a try with a customized datasource to read XML.

See the sample codes : rssnews and tldr

 

The official document for DataSource is located at
