I use

to fetch Yahoo data for Windows Phone 8 and Android
HttpClient With WebClient I can do

WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);

after sending event;

StringReader stream = new StringReader(e.Result)

XmlReader reader = XmlReader.Create(stream);
string humidty = reader.MoveToAttribute("humidity");

but in Windows 8 RT there is no such thing.

how can I fetch the following data? >http://weather.yahooapis.com/forecastrss?w=2343732&u=c

You can use HttpClient class, something like this :

public async static Task<string> GetHttpResponse(string url)
    var request = new HttpRequestMessage(HttpMethod.Get, url);
    request.Headers.Add("UserAgent", "Windows 8 app client");

    var client = new HttpClient();
    var response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);

    if (response.IsSuccessStatusCode)
      return await response.Content.ReadAsStringAsync();
     throw new Exception("Error connecting to " + url +" ! Status: " + response.StatusCode);

Simpler version would be just :

public async static Task<string> GetHttpResponse(string url)
    var client = new HttpClient();
    return await client.GetStringAsync(url);

But if http error occurs GetStringAsync will throw HttpResponseException, and as far I can see there is no http status indicated except in exception message.

UPDATE: I didn't noticed that you in fact you are trying to read RSS Feed, you don't need HttpClient and XML parser, just use SyndicationFeed class, here is the example :
