您好，下面是我正在使用的 xml 示例。我经历了各种我能想到的能够从 personData 节点开始并迭代结果的选项，除非我从根目录向下手动导航每个子节点，否则我似乎没有尝试过任何尝试。谁能建议我如何在不从根开始的情况下做到这一点

我的代码目前是

using (var r = File.OpenText(@"C:\S\sp.xml"))
        {
            XPathDocument document = new XPathDocument(XmlReader.Create(r));
            XPathNavigator xPathNav = document.CreateNavigator();

            XmlNamespaceManager nsmgr = new XmlNamespaceManager(xPathNav.NameTable);
            nsmgr.AddNamespace("g2", "http://person.transferobject.com/xsd");

            XPathNodeIterator xni = xPathNav.Select("/g2:companys/g2:company/g2:person/g2:personData", nsmgr);

            foreach (XPathNavigator nav in xni)
                Console.WriteLine(nav.Name);
        }

我知道您正在使用 XPath，但是由于您对 XPath 有一个答案，我将使用 Linq 给出一个答案

using System;
using System.Linq;
using System.Xml.Linq;

namespace xmlTest
{
    class Program
    {
        static void Main()
        {
            XDocument doc = XDocument.Load("C:\\Users\\me\\Desktop\\so.xml");
            var personDataDetails = (from p in doc.Descendants().Elements()                                     
                                     where p.Name.LocalName == "personData"
                                         select p);

            foreach (var item in personDataDetails)
            {
                Console.WriteLine(item.ToString());
            }

            Console.ReadKey();
        }
    }
}

personData您是否只是在问如何在不列出完整路径的情况下遍历节点？如果这就是你想要做的，你可以这样做：

XPathNodeIterator xni = xPathNav.Select("//g2:personData", nsmgr);
