Windows Phone分析XML字符串

Question

我试图解析这个XML作为来自Virtual Earth的响应检索;

我找过任何答案，可能适用于我在这里或某处。但是每个人都以其他方式询问他们想要什么，而我什么都找不到。我只想获得由“Address”组成的“Locality”值作为字符串值。

我把这个XML命名为MyXMLString。

在此先感谢。

你可以用XDocument.Parse：

XDocument doc = XDocument.Parse(text); 
// Just as an example of using the namespace... 
XNamespace ns = "http://schemas.microsoft.com/search/local/ws/rest/v1"; 
foreach (var location in doc.Descendants(ns + "Address")) 
{ 
    Console.WriteLine(location.Element(ns + "Locality").Value); 
} 

如果Parse是不是在Windows Phone 7的使用，你可以使用一个StringReader：

var reader = new StringReader(text); 
XDocument doc = XDocument.Load(reader); 

或者，如果是不起作用：

var bytes = Encoding.UTF8.GetBytes(text); 
var stream = new MemoryStream(bytes); 
XDocument doc = XDocument.Load(stream);
