XDocument获取命名空间为(RSS提要)的元素值

Question

我正在从RSS提要中获取一些值，但在获取元素标记中包含名称空间的值时遇到了困难。我已经尝试将名称空间添加到值的查找中，但我总是得到空

你知道如何做到这一点吗？

Feedhttps://wegotthiscovered.com/movies/feed/

元素xmlns:content="；http://purl.org/rss/1.0/modules/content/">

命名空间内容：编码

public async Task<bool> GetNewsFeeds()
{
Database db = new Database();
Dictionary<string, string> dictionary = new Dictionary<string, string>();
dictionary.Add("https://wegotthiscovered.com/movies/feed/", "Movie");
dictionary.Add("https://wegotthiscovered.com/blu-ray/feed/", "Blu-ray");
dictionary.Add("https://wegotthiscovered.com/reviews/feed/", "Reviews");
dictionary.Add("https://wegotthiscovered.com/featured/feed/", "Featured");
dictionary.Add("https://wegotthiscovered.com/galleries/feed/", "Galleries");
db.DeletMovieNews();
foreach (var pair in dictionary.ToList())
{
try
{
if (PhysicalDevice.HasInternetConnection())
{
XDocument doc = XDocument.Load(pair.Key);
XNamespace nsSys = "http://purl.org/rss/1.0/modules/content/";
var entries = (from item in doc.Descendants("item")
select new Movie_News
{
Content = item.Element(nsSys + "encoded").Value, // ISSUE HERE 
Link = item.Element("link").Value,
PublishedDate = item.Element("pubDate").Value,
Title = item.Element("title").Value,
Description = item.Element("description").Value,
GroupName = "News",
FeedName = pair.Value
});
List<Movie_News> newsCollection = entries.ToList();
if (newsCollection.Count() != 0)
{
using (var rateGate = new RateGate(40, TimeSpan.FromSeconds(10)))
{
rateGate.WaitToProceed();
foreach (Movie_News item in newsCollection)
{
string regex = @"((http|ftp|https)://)?([w_-]+(?:(?:.[w_-]+)+))([w.,@?^=%&:/~+#-]*[w@?^=%&/~+#-])?";
Match match = Regex.Match(item.Description, regex);
if (match.Success)
{
item.ImageUrl = match.Value;
item.B64Image = await DownloadImage(item.ImageUrl);
}

item.Description =  item.Description.Remove(0, item.Description.IndexOf("</div>"));
item.Description = item.Description.Replace("</div>","");

db.InsertNewsData(item);
}
}
}

return true;
}
}
catch(Exception ex) 
{
return false;
}
}
return true;
}

}
