我想提取每个项目。

string url = "https://news.google.com/news?pz=1&cf=all&ned=uk&hl=en&q=/"birch/"&cf=all&output=rss"

XmlDocument doc = new XmlDocument();
doc.Load(url);
XmlElement root = doc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("item")

foreach (XmlNode node in nodes)
{
    // do stuff
}

但我似乎无法访问每个项目的网址？

有什么建议吗？

答案 0 :(得分：1)

您可以使用System.Xml.Linq

以下代码对我有用。

XDocument xDoc = XDocument.Load(@"Filepath/XMLFile1.xml");
List<XElement> LXElement = xDoc.Root.Element("channel").Elements("item").ToList();

foreach (XElement iElement in LXElement)
{
    Console.WriteLine(iElement.Element("title").Value);
    Console.WriteLine(iElement.Element("link").Value);
    Console.WriteLine(iElement.Element("guid").Value);
    Console.WriteLine(iElement.Element("pubDate").Value);
    Console.WriteLine(iElement.Element("description").Value);
}
