无法提取XML文件中元素的属性值

Question

我有一个XML模式文件，我正在尝试提取每个元素的属性值，即在此XM1模式文件（下面提到的文件）中。

您可能已经注意到，XML文件中大约有20个元素，因此，我正在寻找一种自动方法来从元素中提取数据，以避免手动工作。

对于每个元素，我需要以下属性值：类型，标签，CompType，只读，隐藏和必需。

例如，以下是XML文件中的一些元素：

<element type="xpowercomponent_FeaturedTiles" UID="40204fc9b5424b349e03134d777d29bc" label="Featured Tiles" readonly="false" hidden="false" default="" required="false" Component="" CompTypes="ThemedTileSetComponent;ThemedTileSetElectedComponent;" AutoEmbed="" WrappedUp="" AllowWrappingChange="" />

应该输出到控制台的预期结果将是：xpowercomponent_FeaturedTiles，精选图块，ThemedTileSetComponent，ThemedTileSetElectedComponent，readonly =“ false”，hidden =“ false”，需要= “假”

我已经创建了这个C＃应用程序，尝试并实现了上面描述的内容，但是并没有给我想要的结果。我不确定逻辑是否正确，或者是否有更好的方法。

C＃：

public static void Parse()
{    
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(@"D:\New Text Document.xml");

        var captureElements = new List<CustomElements>();
        var xdocument = xmlDoc.ToXDocument();
        foreach (var element in xdocument.Elements())
            foreach (var node in element.Elements()) //childs...
            {

                if (node.Name.LocalName.Equals("ElementType"))
                {
                    foreach (var scopeNode in node.Elements())
                    {
                        if (scopeNode.Name.LocalName.Equals("element"))
                        {
                            var xml = XElement.Parse(scopeNode.ToString());
                            var customElement = new CustomElements();

                            customElement.Type = xml.Attribute("type")?.Value;
                            customElement.Label = xml.Attribute("label")?.Value;
                            customElement.CompTypes = xml.Attribute("CompTypes")?.Value;
                            customElement.Readonly = xml.Attribute("readonly")?.Value;
                            customElement.Hidden = xml.Attribute("hidden")?.Value;
                            customElement.Require = xml.Attribute("required")?.Value;

                            captureElements.Add(customElement);  
                        }

                    }
                }
            }
        }
    }
}
public static class DocumentExtensions
{
    public static XmlDocument ToXmlDocument(this XDocument xDocument)
    {
        var xmlDocument = new XmlDocument();
        using (var xmlReader = xDocument.CreateReader())
        {
            xmlDocument.Load(xmlReader);
        }
        return xmlDocument;
    }

    public static XDocument ToXDocument(this XmlDocument xmlDocument)
    {
        using (var nodeReader = new XmlNodeReader(xmlDocument))
        {
            nodeReader.MoveToContent();
            return XDocument.Load(nodeReader);
        }
    }
}
public class CustomElements
{
    public string Type { get; set; }
    public string Label { get; set; }
    public string CompTypes { get; set; }
    public string Readonly { get; set; }
    public string Hidden { get; set; }
    public string Require { get; set; }
}

尝试嵌套词典：

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

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);
            XNamespace ns = doc.Root.GetDefaultNamespace();

            XElement TopTier = doc.Descendants(ns + "ElementType").Where(x => (string)x.Attribute("name") == "TopTier").FirstOrDefault();

            Dictionary<string, Dictionary<string, string>> dict = TopTier.Elements(ns + "element")
                .GroupBy(x => (string)x.Attribute("type"), y => y.Attributes().Skip(1)
                    .GroupBy(a => a.Name.LocalName, b => (string)b)
                    .ToDictionary(a => a.Key, b => b.FirstOrDefault()))
                    .ToDictionary(x => x.Key, y => y.FirstOrDefault());
        }
    }
}
