Question

我试图从CNN的RSS Feed中获取图片价值，但我在尝试获取图片时遇到了问题。

我追求的是

的价值

 <media:content medium="image" 
                url="https://cdn.cnn.com/cnnnext/dam/assets/180513143656-police-masks-surabaya-hp-video.jpg" 
                height="144" 
                width="256" />

使用下面的代码，我可以看到我之后的内容，但我无法检索该值。

foreach (SyndicationElementExtension extension in f.ElementExtensions)
{
    XElement element = extension.GetObject<XElement>();
    if (element.HasAttributes)
    {
        foreach (var attribute in element.Attributes())
        {
             //How to get value here    
        }
    }
}

如何检索图像值？
