Help with example rss news in setting custom rss address

[cmall]

Hello, I am trying to customize the rss address to the following "

http://www.pamakhouse.gr/forums/external.php?do=rss&type=newcontent&sectionid=1&days=120&count=10

This is my model:

XmlListModel {
id: feedModel

    source: "http://" + window.currentFeed
    query: "/rss/channel/item"

XmlRole { name: "pubDate"; query: "pubDate/string()" }
XmlRole { name: "title"; query: "title/string()" }
// Remove any links from the description
XmlRole { name: "description"; query: "description/string()" }
//XmlRole { name: "image"; query: "media:content/@url/string()" }
XmlRole { name: "link"; query: "link/string()" }
XmlRole { name: "guid"; query: "guid/string()" }
}

But I jus get a blank screen. Does anyone know what is wrong? Thanks!
