silverlight rss feed displayer
· May 22, 11:30 PM by Thijs Kroesbergen
Tonight I built a small silverlight application which reads this site’s rss feed and displays it in a “nice” format.
See SilveRSS in action!
Getting the animation done was quite simple too, but I did some fine-tuning inside the XAML code myself. Probably because I don’t know Expression Blend well enough yet.
The biggest challenge was to have the Silverlight applet decypher the rss-xml layout. But actually all that is very basic .NET programming.
The code to retrieve the rss data and parse the XML looks like this:
Uri uri = new System.Uri("http://www.brokenwire.net/bw/rss");
BrowserHttpWebRequest request = new BrowserHttpWebRequest(uri);
HttpWebResponse response = request.GetResponse();
StreamReader responseReader = new StreamReader(response.GetResponseStream());
string rawvalue = responseReader.ReadToEnd();
XmlReader xr = XmlReader.Create(new StringReader(rawvalue));
while (xr.ReadToFollowing("item"))
{
//RssItem is a struct to contain the data for one item
RssItem item;
xr.ReadToFollowing("title");
item.title = xr.ReadElementContentAsString();
xr.ReadToFollowing("description");
item.description = Strip(xr.ReadElementContentAsString());
xr.ReadToFollowing("link");
item.link = xr.ReadElementContentAsString();
// Add items to a list
_rssItems.Add(item);
}
Controlling the animations is just a matter of catching the Storyboard “Completed” events.
Other examples I found on the web are using the power of the webserver to create XAML code on the server, and displaying that on the client. But I didn’t want to and didn’t need to write any server-side code in this example.

What namespace is Strip in or is it something your rolled yourself?
Thanks for the example :)

Strip() is a home-made function, simply drops all HTML tags from a piece of text…
