从网址加载Rss Feed

Question

Have some problems while loading XMLDocument. When I try to load url it throws exception:

"System.Xml.XmlException: 'Ссылка на необъявленный объект подстановки "raquo" ".

What`s wrong?

C# code:

XmlDocument rssXmlDoc = new XmlDocument();
rssXmlDoc.Load(sourceUrl);

XmlNodeList rssNodes = rssXmlDoc.SelectNodes("rss/channel/item");

foreach (XmlNode item in rssNodes)
{
    XmlNode rssSubNodeTitle = item.SelectSingleNode("title");
    string title = rssSubNodeTitle != null ? rssSubNodeTitle.InnerText : "";
    Console.WriteLine(title);
}

Making a few changes to your code and providing the correct URL RSS you can have these results:

String url = "https://keddr.com/feed/";
XmlReader reader = XmlReader.Create(url);
SyndicationFeed feed = SyndicationFeed.Load(reader);
reader.Close();

foreach (SyndicationItem item in feed.Items)
{
    Console.WriteLine("Title: " + item.Title.Text);
    Console.WriteLine("Publish Date:" + item.PublishDate.ToString("MM/dd/yyyy HH:mm:ss"));
    Console.WriteLine("Link: " + item.Links[0].GetAbsoluteUri().ToString());
    Console.WriteLine(item.Summary.Text");
}

I'll show here only the first result, but, you'll get the idea:
