如何访问媒体的url attr：缩略图和媒体：RSS Feed中的内容元素？

Question

我正在尝试使用我的Zenfolio RSS提要，以便我可以在提要中显示图像。我如何访问媒体的url值：缩略图和媒体：RSS提要中的内容元素？我搜索了高低，并没有找到关于如何访问url值的答案。有一个类似的未答复的SO post。

的元件的例子：

<media:thumbnail url="http://riderdesign.net/img/s11/v35/p449020235-2.jpg" 
        width="400" 
        height="225" 
     /> 
    <media:content url="http://riderdesign.net/img/s11/v35/p449020235-2.jpg" 
        type="image/jpeg" medium="image" 
        width="400" 
        height="225" 
     /> 

我在我的控制器的代码：

Public Function Feed() As ActionResult 
      Dim feedurl As String = "http://riderdesign.net/recent.rss" 
      Using x = XmlReader.Create(feedurl) 
       Dim r As SyndicationFeed = SyndicationFeed.Load(x) 
       Return View(r) 
      End Using 
     End Function 

我认为我有@ModelType System.ServiceModel.Syndication.SyndicationFeed和

@For Each i In ViewData.Model.Items 
    @i.Title.text @<br /> 
    <!--What do i do here to get the url values?--> 
Next

我有我的解决方案。我会在这里发布代码。

代码：

 Public Function Feed() As ActionResult 
     Dim feedurl As String = "http://riderdesign.net/p319394411/recent.rss" 
     Using x = XmlReader.Create(feedurl) 
      Dim r = XDocument.Load(x) 
      Dim mediapfx As XNamespace = "http://search.yahoo.com/mrss/" 

      Dim ml = From item In r.Descendants(mediapfx + "content") Select item 
      Dim medialist = From item In r.Descendants("item") Select New MediaImage With { 
      .Id = item.Element("guid").Value, .ImageUrl = TryGetAttributeValue(item.Element(mediapfx + "content"), "url")} Take 5 
      Return View(medialist) 

     End Using 

    End Function 

    Private Function TryGetAttributeValue(ByVal xe As XElement, ByVal attribute As String) As String 
     If xe IsNot Nothing AndAlso xe.Attribute(attribute) IsNot Nothing Then 
      Return xe.Attribute(attribute).Value 
     Else 
      Return Nothing 
     End If 
    End Function 



Namespace RiderDesignMvcBlog.Core.ViewModels 
    Public Class MediaImage 

     Public Property Id() As String 

     Public Property ImageUrl() As String 

    End Class 
End Namespace 

鉴于：

@ModelType IEnumerable(Of RiderDesignMvcBlog.Core.ViewModels.MediaImage) 

@Code 
    ViewData("Title") = "Feed" 
    Layout = "~/Views/Shared/_Layout4.vbhtml" 
End Code 

<h2>Feed</h2> 
@For Each i In Model 
    @<img src=" @i.ImageUrl" />
