C# 反序列化XMLDocument对象的特定节点

我有下面的一段代码，它接受XMLDocument对象和代码下面提到的格式的xml。我想读取bouding框中4个标签的值：

南纬等

    public static void readXML(XmlDocument document)
    {

        if (document == null)
        {
            throw new ArgumentNullException("document");
        }




        XmlNode specificNode = document.SelectSingleNode("/Response/ResourceSets/ResourceSet/Resources/Location/BoundingBox");

        if (specificNode != null)
        {
            XmlNodeReader specificNodeReader = new XmlNodeReader(specificNode);

            while (specificNodeReader.Read())
            {
                Console.WriteLine(specificNodeReader.Value);
            }
        }
     }

xml如下所示：

因为实际的
xml
有一个名称空间，所以需要将其包含在所使用的任何
Xpath
查询中。因为您已经在
XmlDocument
中加载了xml，所以不需要
XmlReader

XmlNamespaceManager nsm = new XmlNamespaceManager(document.NameTable);
nsm.AddNamespace("ms", "http://schemas.microsoft.com/search/local/ws/rest/v1");
XmlNode boundingBoxNode = document.SelectSingleNode("/ms:Response/ms:ResourceSets/ms:ResourceSet/ms:Resources/ms:Location/ms:BoundingBox", nsm);

if (boundingBoxNode != null)
{
    Console.WriteLine(boundingBoxNode.SelectSingleNode("ms:SouthLatitude", nsm).InnerText);
    Console.WriteLine(boundingBoxNode.SelectSingleNode("ms:NorthLatitude", nsm).InnerText);
    Console.WriteLine(boundingBoxNode.SelectSingleNode("ms:EastLongitude", nsm).InnerText);
    Console.WriteLine(boundingBoxNode.SelectSingleNode("ms:WestLongitude", nsm).InnerText);
}        

也可以在Linq to Xml中执行此操作：

XNamespace ns = "http://schemas.microsoft.com/search/local/ws/rest/v1";

var boundingBox = document
                .Descendants(ns + "Response")
                .Descendants(ns + "ResourceSets")
                .Descendants(ns + "ResourceSet")
                .Descendants(ns + "Resources")
                .Descendants(ns + "Location")
                .Descendants(ns + "BoundingBox");

if (boundingBox != null)
{
    Console.WriteLine(boundingBox.Descendants(ns + "SouthLatitude").First().Value);
    Console.WriteLine(boundingBox.Descendants(ns + "NorthLatitude").First().Value);
    Console.WriteLine(boundingBox.Descendants(ns + "EastLongitude").First().Value);
    Console.WriteLine(boundingBox.Descendants(ns + "WestLongitude").First().Value);
}        

我们应该做到这一点。当然，亨克·霍尔特曼在早些时候的回答中赢得了很多赞誉
 您能给出这种特殊情况下的使用示例吗？您的XML无效，因为您不能使用数字作为元素。如果您认为当前的答案没有帮助，那么发布更详细的XML示例也可能会有所帮助。以及您正试图从中提取的确切值。我已经发布了实际的XML文档。标题中的“反序列化”一词可能会误导您-您似乎只需要特定节点的值：）
        XmlNode specificNode = document.SelectSingleNode("/Response/ResourceSets/ResourceSet/Resources/Location/BoundingBox");
        if (specificNode != null)
        {
            foreach (XmlNode child in specificNode.ChildNodes)
            {
                Console.WriteLine(child.InnerText);
            }
        }
