如何在C#中过滤SOAP结果客户端？

using System;
using System.Xml;

namespace SOAPClientExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建SOAP客户端代理类
            MySoapServiceClient client = new MySoapServiceClient();

            // 调用SOAP方法并获取响应消息
            string soapResponse = client.MySoapMethod();

            // 将SOAP响应消息转换为XML文档对象
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.LoadXml(soapResponse);

            // 使用XPath表达式选择所需的节点
            XmlNodeList nodes = xmlDoc.SelectNodes("//Result/Item");

            // 遍历选择的节点并输出结果
            foreach (XmlNode node in nodes)
            {
                Console.WriteLine(node.InnerText);
            }
        }
    }
}

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <Result>
            <Item>Item 1</Item>
            <Item>Item 2</Item>
            <Item>Item 3</Item>
        </Result>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
