Question

我已经在谷歌上呆了一段时间，但我只是难倒了。我需要解析这种性质的xml。我似乎无法跳到中间的元素，例如夹。我限制了xml，因为有很多＆＃39;文件夹＆＃39;元素。任何指导将不胜感激。我是在FolderID元素的属性ID之后。

Answer 1

你应该学习血清化。在C＃中将XML转换为对象非常容易。 https://www.codeproject.com/Articles/483055/XML-Serialization-and-Deserialization-Part

那说，这将为您提供您所追求的数据。它不是非常可重复使用，并且不会帮助您使用除具有该属性的一个实例的xml文件之外的任何xml文件，但这就是您所追求的内容。

string FolderId;
string ChangeKey;
using (StreamReader sr = new StreamReader("c:\\myfile.xml"))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {
        if (line.Contains("<t:FolderId Id="))
        {
            try
            {
                var lineArray = line.Split('\"');
                FolderId = lineArray[1];
                ChangeKey = lineArray[3];
            }
            catch
            {
                // handle exception
            }               
        }
    }
}

您可以使用XSD.exe创建架构类。然后使用XML反序列化器，您可以反序列化/解析xml到对象

Answer 3

LINQ to XML是最好的.NET XML Parsing API。看到 https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/linq/xdocument-class-overview

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;

namespace ConsoleApp12
{
    class Program
    {
        static void Main(string[] args)
        {

            var doc = XDocument.Load(@"c:\temp\foo.xml");
            var ns = (XNamespace)"http://schemas.microsoft.com/exchange/services/2006/types";

            var folders = doc.Descendants(ns + "Folder");

            foreach (var e in folders)
            {
                var folderId = e.Element(ns + "FolderId").Attribute("Id").Value;
                Console.WriteLine(folderId);
            }

            Console.WriteLine("Hit any key to exit.");
            Console.ReadKey();

        }
    }
}

Answer 4

使用xml linq

            XDocument doc = XDocument.Load(FILENAME);

            List<XElement> folders = doc.Descendants().Where(x => x.Name.LocalName == "Folder").ToList();
            XNamespace tNs = folders.FirstOrDefault().GetNamespaceOfPrefix("t");
            XElement id_AAMkADk5MmY1ZThmLTM2MzAtNGVh = folders.Where(x => (string)x.Element(tNs + "FolderId").Attribute("Id") == "AAMkADk5MmY1ZThmLTM2MzAtNGVh").FirstOrDefault();
