获取特定的Xml节点

Question

如何从此Feed中获取"入口"节点

http://www.google.com/alerts/feeds/14392773026536511983/5526937985735563348

我试过linq到xml,但我认为因为代码后面的条目标签的现有属性不起作用.

string url = "http://www.google.com/alerts/feeds/14392773026536511983/5526937985735563348";

WebClient c = new WebClient();

string xml = ASCIIEncoding.Default.GetString(c.DownloadData(url));

XDocument doc = XDocument.Parse(xml);

var entries = doc.Descendants("entry");

提前致谢,

您没有指定命名空间.试试这个:

XNamespace atom = "http://www.w3.org/2005/Atom";
var entries = doc.Descendants(atom + "entry");

顺便说一句,我不会使用ASCII,或者DownloadData......用来WebClient.DownloadString为你处理编码.或者确实,只需使用XDocument.Load(url):

例如:

string url = ...;

XDocument doc = XDocument.Load(url);
XNamespace atom = "http://www.w3.org/2005/Atom";
var entries = doc.Descendants(atom + "entry");
Console.WriteLine(entries.Count()); // Prints 20
