对Scott Gu的Silverlight Sample--DiggSample的修改

由于Scott Gu的Sample中的数据已经不能获取，于是花了点时间把数据获取重写了下

仍然是Linq to XML，具体代码如下

XDocument xmlStories = XDocument.Parse(xmlContent);

XNamespace digg = "http://digg.com/docs/diggrss/";

XNamespace media = "http://search.yahoo.com/mrss/";

var stories = from story in xmlStories.Descendants("item")

where story.Element(media + "thumbnail") != null &&

story.Element(media + "thumbnail").Attribute("url") != null &&

story.Element(media + "thumbnail").Attribute("url").Value.EndsWith(".jpg")

select new DiggStory

{

//Id = (int)story.Attribute("id"),

Title = ((string)story.Element("title")).Trim(),

Description = Regex.Replace(((string)story.Element("description")).Trim(), @"<(.[^>]*)>", "", RegexOptions.IgnoreCase),

ThumbNail = (string)story.Element(media + "thumbnail").Attribute("url"),

HrefLink = new Uri((string)story.Element("link")),

NumDiggs = (int)story.Element(digg + "diggCount"),

UserName = (string)story.Element(digg + "submitter").Element(digg + "username"),

};

还有一个地方，大家在做这个Demo的时候，注意在SL3中已经没有WateredTextBox，新的控件为DataPickerTextBox
