How do I place XML data in a Selection Dialog

[honeyhong]

"Example Selection Dialog":http://i214.photobucket.com/albums/cc71/honeyhong/Capture-1.jpg

I have a Selection Dialog like the one in the picture I attached.
The data in the selection dialog were preset like this.

@
SelectionDialog
{
id:root
titleText:"Select a Box"
model:ListModel
{
ListElement { name: "Inbox"; boxId: 0}
ListElement { name: "Today"; boxId: 1}
ListElement { name: "Next"; boxId: 2}
ListElement { name: "Later"; boxId: 3}
}

delegate: itemDelegate
Component {
id: itemDelegate
MenuItem {
text: model.name
onClicked: {
selectedIndex = index;
root.accept();
}
}
}

} //close

Right now, I want to retrieve an XML data and display it in the selection dialog instead of setting it manually by myself.
My XML data is this

@
XmlListModel {
id: photo1
property string feedUrl: ""
property bool loading: status == XmlListModel.Loading

            source: "(_example url_)"
            query: "/plist/array/dict"
            XmlRole { name: "photoTitle"; query: "string[1]/string()";}
       }
        }

@
To be clearer, instead of keying in Inbox, Today etc. by myself into the Selection Dialog,
I want to retrieve the XML data that display item e.g(October, November, December) into the Selection Dialog.
Any idea how to do it? Really need help.
