我已经看到了这个问题,但我没有看到答案..
所以我得到这个错误:
The ':' character, hexadecimal value 0x3A, cannot be included in a name.
在此代码上:
XDocument XMLFeed = XDocument.Load("http://feeds.foxnews.com/foxnews/most-popular?format=xml");
XNamespace content = "http://purl.org/rss/1.0/modules/content/";
var feeds = from feed in XMLFeed.Descendants("item")
select new
{
Title = feed.Element("title").Value,
Link = feed.Element("link").Value,
pubDate = feed.Element("pubDate").Value,
Description = feed.Element("description").Value,
MediaContent = feed.Element(content + "encoded")
};
foreach (var f in feeds.Reverse())
{
....
}
一个项目看起来像这样:

我想要的只是获取“http://global.fncstatic.com/static/managed/img/Politics/panetta_hearing_030712.jpg”,然后在此之前检查 content:encoded 是否存在..
谢谢。
编辑: 我找到了一个示例,我可以显示和编辑尝试处理它的代码..
EDIT2: 我以丑陋的方式做到了:
text.Replace("content:encoded", "contentt").Replace("xmlns:content=\"http://purl.org/rss/1.0/modules/content/\"","");
然后以正常方式获取元素:
MediaContent = feed.Element("contentt").Value
