Question

我正在编写一个加载XML文件的程序，并使用这些数据在Unity中创建对象。创建XmlSerializer对象会导致以下错误：

InvalidOperationException: The XML element named 'compatibility' from namespace '' 
is already present in the current scope. Use XML attributes to specify another
XML name or namespace for the element.

这表明Unity在某些看不见的/内部项目代码上有[XmlElement(ElementName = "compatibility")]或类似的属性。作为旁注，我编写了一个没有这个问题的简单控制台应用程序，使用完全相同的代码（少了一两个Unity特定函数）。

我无法编辑我正在读取的XML（因为它是由另一个程序生成的），它没有指定命名空间。

我已尝试在序列化类中设置部分或全部元素的Namespace属性，但我总是以“意外的＆lt; eagle xmlns ='1,4,4”或类似错误结束。我也试过通过XSD工具生成文件，与上面的“意外”错误相同。最后，我尝试创建一个XmlNamespaceManager对象，创建并推送一个新的命名空间，但它似乎没有效果。

我该怎么做才能解决这个问题？

XML片段（注意，不包括整个文件，因为它大约有500行.XML格式正确）

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE eagle SYSTEM "eagle.dtd">
<eagle version="8.4.3">
<drawing>
<settings>
<setting alwaysvectorfont="no"/>
<setting verticaltext="up"/>
</settings>
<grid distance="50" unitdist="mil" unit="mil" style="lines" multiple="1" display="no" altdistance="5" altunitdist="mil" altunit="mil"/>
<layers>
<layer number="1" name="Top" color="4" fill="1" visible="yes" active="yes"/>
<layer number="2" name="Route2" color="1" fill="3" visible="no" active="no"/>
<layer number="3" name="Route3" color="4" fill="3" visible="no" active="no"/>

类XML被序列化为：

using System;
using System.Xml.Serialization;

namespace Assets.Scripts
{
    [Serializable()]
    [XmlRoot(ElementName = "eagle")]
    public partial class EagleXML
    {
        [XmlElement(ElementName = "compatibility", Order = 0)]
        public CompatibilityNote CompatibilityNote1 { get; set; }

        [XmlElement(ElementName = "drawing", Order = 1)]
        public Drawing Drawing { get; set; }

        [XmlElement(ElementName = "compatibility", Order = 2)]
        public CompatibilityNote CompatibilityNote2 { get; set; }

        [XmlAttribute(AttributeName = "version")]
        public string Version { get; set; }
    }

    [Serializable()]
    public partial class CompatibilityNote
    {

    }

    [Serializable()]
    public partial class Drawing
    {

    }
}

进行反序列化的类：

using System;
using System.Xml;
using System.Xml.Schema;
using System.Xml.Serialization;
using UnityEngine;

namespace Assets.Scripts
{
    public class PCBScript : MonoBehaviour
    {

        public const string brdPath = @"ProperPathToXmlFile";

        void Start()
        {
            XmlReaderSettings settings = new XmlReaderSettings();

            XmlUrlResolver resolver = new XmlEagleUrlResolver();

            settings.ProhibitDtd = false;
            settings.ValidationType = ValidationType.None;
            settings.ValidationEventHandler += new ValidationEventHandler(ValidationFailed);
            settings.XmlResolver = resolver;

            XmlSerializer serializer = new XmlSerializer(typeof(EagleXML));

            EagleXML loadedFile = (EagleXML)serializer.Deserialize(XmlReader.Create(brdPath, settings));

            Console.WriteLine("Loaded xml");
        }

        private void ValidationFailed(object sender, ValidationEventArgs e)
        {
            Console.WriteLine("Failed to validate");
            Console.WriteLine(e.Message);
            Console.WriteLine("\r\n");
        }
    }
}

两个具有相同名称的XML元素和XMLSerializer
