        </deviceList>
        <presentationURL>someip</presentationURL>
    </device>
</root>

我需要找到这个节点：

<service>
                                <serviceType>urn:schemas-upnp-org:service:WANPPPConnection:1</serviceType>
                                <serviceId>urn:upnp-org:serviceId:WANPPPConn1</serviceId>
                                <controlURL>/upnp/control/WANPPPConn1</controlURL>
                                <eventSubURL>/upnp/event/WANPPPConn1</eventSubURL>
                                <SCPDURL>/pppcfg.xml</SCPDURL>
                            </service>

通过此标记和innertext：

<serviceType>urn:schemas-upnp-org:service:WANPPPConnection:1</serviceType>

但这也可能是这样的：

<serviceType>urn:schemas-upnp-org:service:WANIPConnection:1</serviceType>

找到此节点后，我想从此节点获取innertext：

<controlURL>/upnp/control/WANPPPConn1</controlURL>

我怎么能这样做？

尝试这样的事情......要使用，请将XML保存到文件并复制代码。它会将整个XML反序列化为一个对象，然后您可以更轻松地管理它....

... Usings

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

类....

    static void Main(string[] args)

        // Deserialize to object
        XmlSerializer serializer = new XmlSerializer(typeof(Root));
        using (FileStream stream = File.OpenRead(@"xml.xml"))
        {
            dezerializedXML = (Root)serializer.Deserialize(stream);
        } // Put a break-point here, then mouse-over dezerializedXML

        // the next line will get both of the services at that level in your XML you can probably do something with that
        var v = (dezerializedXML.Device.DeviceList.Device.DeviceList.Device.ServiceList.Service);
    }

确定不是最短的答案，但希望它有所帮助......

Select Nodes Using XPath Navigation就是您所需要的。

和XPath Example

C＃Xml选择节点包含的节点包含innertext包含的文本
