<span style="font-family: Arial; background-color: rgb(255, 255, 255);">在程序有时候需要从文本中读取数据，或者把数据保存到文件中，使用XML文件来存储数据是一个不错的选择。下面介绍一下在Unity3D中使用C#如何进行XML文件的读写。</span>

1、需要引入的包

using UnityEngine;
using System.Collections;
using System.Xml; 2、编辑你的XML文件

<?xml version="1.0" encoding="utf-8"?>
<RoleRoot>

<Role faction="0">
<BaseAttribute grade="1" force="2" spirit="1" agility="1" endurance="1" wisdom="1"/>
<FightAttribute hp="1" mp="1" generalHurt="1" generalDefense="1" skillHurt="1"
skillDefense="1" generalHurtFactor="1" generalDefenseFactor="1"
skillHurtFactor="1" skillDefenseFactor="1"/>
<RateAttribute violenceRate="0" killRate="0" breakDefenseRate="0" duckRate="0"
withstandRate="0" hitRate="0"/>
<ValueAttribute attackOrder="0" money="0" goldBullions="0" bags="0" achievement="0"
experience="0" vitality="0"/>
</Role>
</RoleRoot>

<span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 18px; line-height: 26px;"></span><pre name="code" class="csharp">XmlDocument xmlDoc = new XmlDocument();
TextAsset textAsset = (TextAsset)Resources.Load("createRole");
xmlDoc.LoadXml(textAsset.text);
//xmlDoc.LoadXml(Application.dataPath + @"\createRole.xml");
XmlNodeList nodeList = xmlDoc.SelectNodes("RoleRoot/Role");
XmlNode node;
switch (faction)
{
case FACTION.Monk:
node = nodeList[0];
break;
case FACTION.Taoist:
node = nodeList[1];
break;
case FACTION.Flower:
node = nodeList[2];
break;
default:
node = nodeList[3];
break;
}

//XmlNode baseAttribute=node.SelectNodes("BaseAttribute");
XmlNode baseAttribute = node.ChildNodes[0];
grade = XmlConvert.ToInt32(baseAttribute.Attributes["grade"].Value);
force = XmlConvert.ToInt32(baseAttribute.Attributes["force"].Value);
spirit = XmlConvert.ToInt32(baseAttribute.Attributes["spirit"].Value);
agility = XmlConvert.ToInt32(baseAttribute.Attributes["agility"].Value);
endurance = XmlConvert.ToInt32(baseAttribute.Attributes["endurance"].Value);
wisdom = XmlConvert.ToInt32(baseAttribute.Attributes["wisdom"].Value);

</span></p><span style="color: rgb(51, 51, 51); font-family: Arial; line-height: 26px; font-size: 18px;">出现这个错误的原因是因为Unity3D加载XML文件的时候，XML文件必须保存为UTF-8编码的格式，同时还必须去掉开头的两个字节（BOM）用来标识UTF-8用的。这时你可以选择一些编辑工具另存为UTF-8,（有些工具默认的会为UTF-8编码添加一个BOM标识），比如你可以使用eclipse导出xml,这样就不含有BOM标识。还有其他一些解决办法：给个链接吧：<a target=_blank target="_blank" href="http://answers.unity3d.com/questions/10904/xmlexception-text-node-canot-appear-in-this-state.html" style="color: rgb(255, 153, 0); text-decoration: none;">http://answers.unity3d.com/questions/10904/xmlexception-text-node-canot-appear-in-this-state.html</a></span>
