【问题描述】：

当我尝试解析这个 xml 时遇到问题

<?xml version="1.0" encoding="ISO-8859-1"?>
<Objects>
  <Object type="0x141" id="Amulet of Resurrection">
    <Class>Equipment</Class>
    <Item />
    <ActivateOnEquip stat="20" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="21" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="22" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="26" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="27" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="28" amount="2">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="0" amount="20">IncrementStat</ActivateOnEquip>
    <ActivateOnEquip stat="3" amount="20">IncrementStat</ActivateOnEquip>
  </Object>
</Objects>

我的程序刚刚读取了第一个 ActivateOnEquip，但我希望它读取所有内容。

这是我的程序：

using System;
using System.Xml;

namespace ParseXML

    internal class Program
    
        private static void Main(string[] args)
        
            ParseXMLEquip(@"..\..\obj\Debug\Object\Test.xml");
            Console.ReadLine();
        

        private static void ParseXMLEquip(string fileName)
        
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            XmlNodeList EquipNodes = xmlDocument.SelectNodes("//*");
            
                foreach (XmlNode EquipNode in EquipNodes)
                
                    XmlNode Stat = EquipNode["ActivateOnEquip"];

                    if (Stat != null)
                    
                        switch (Stat.Attributes["stat"].InnerText)
                        
                            case "0":
                            
                                Console.WriteLine("Hp: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "3":
                            
                                Console.WriteLine("Mp: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "20":
                            
                                Console.WriteLine("Attack: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "21":
                            
                                Console.WriteLine("Defense: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "22":
                            
                                Console.WriteLine("Speed: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "28":
                            
                                Console.WriteLine("Dexterity: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "26":
                            
                                Console.WriteLine("Vitality: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                            case "27":
                            
                                Console.WriteLine("Wisdom: " + Stat.Attributes["amount"].InnerText);
                            
                                break;
                        
                    
                
            
        
    

控制台只写Attack : 2 但我想要这个

Attack : 2 
Defense : 2 
Speed : 2 
Vitality : 2 
Wisdom : 2 
Dexterity : 2 
HP : 20
MP : 20

【参考方案1】：

使用 Linq2Xml 怎么样

Dictionary<string, string> mapping = new Dictionary<string, string>()

    "0","Hp",
    "3","Mp",
    "20","Attack",
    "21","Defence",
    "22","Speed",
    "28","Dexterity",
    "26","Vitality",
    "27","Wisdom",
;

var result = XDocument.Load(filename)
             .Descendants("ActivateOnEquip")
             .Select(x => new  stat = x.Attribute("stat").Value, amount = x.Attribute("amount").Value )
             .ToList();

foreach(var item in result)

    Console.WriteLine( mapping[item.stat] + ": " + item.amount);

我可以在此代码中添加类似元素 吗？我试着做到了，但遇到了和以前一样的问题？非常感谢@EZI
