在游戏开发中，Xml常常被用来作为技能配置、地图配置、人物动作配置等配置文件。Unity3d内置的Xml库让我们非常方便地就能够新建Xml和读取Xml。

以下是一个样例，新建了一个Xml文档，而且读取它。

using UnityEngine;
using System.Collections;
using System.IO;
using System.Xml;
using System.Text;public class XmlTest : MonoBehaviour {XmlElement m_roleMotions = null;//人物动作;XmlElement m_skills = null;//人物技能;// Use this for initializationvoid Start () {//CreateXml();//ReadXml();ReadFileToXml();}// Update is called once per framevoid Update () {}void CreateXml(){string filepath = Application.dataPath + "/Resources/1013000.xml";if (!File.Exists(filepath)){//创建xml实例;XmlDocument xmlDoc = new XmlDocument();//创建character;XmlElement root = xmlDoc.CreateElement("character");/***创建roleMotions Start***/XmlElement roleMotions = xmlDoc.CreateElement("roleMotions");XmlElement motionInfo = xmlDoc.CreateElement("motionInfo");XmlElement motion = xmlDoc.CreateElement("motion");motion.SetAttribute("clipName", "enter_ready");motion.SetAttribute("isLoop", "false");motion.SetAttribute("moveEndTime", "0");motion.SetAttribute("moveStartTime", "0");motionInfo.AppendChild(motion);roleMotions.AppendChild(motionInfo);root.AppendChild(roleMotions);/***创建roleMotions End***//***创建skills Start***/XmlElement skills = xmlDoc.CreateElement("skills");XmlElement skill = xmlDoc.CreateElement("skill");skill.SetAttribute("name", "普攻");skill.SetAttribute("motion", "RMT_Attack1");skills.AppendChild(skill);root.AppendChild(skills);/***创建skills End***/xmlDoc.AppendChild(root);xmlDoc.Save(filepath);}else{Debug.LogError("File hava exist");}}void ReadXml(){string filepath = Application.dataPath + "/Resources/1013000.xml";if (!File.Exists(filepath)){Debug.LogError("xml file not exist");return;}XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(filepath);//获取全部子节点;XmlNodeList nodeList = xmlDoc.SelectSingleNode("character").ChildNodes;foreach(XmlNode child in nodeList){if (child.Name == "roleMotions"){m_roleMotions = child as XmlElement;}else if (child.Name == "skills"){m_skills = child as XmlElement;}}Debug.Log("m_roleMotions = " + m_roleMotions.InnerXml);Debug.Log("m_skills = " + m_skills.InnerXml);}void ReadFileToXml(){string filepath = "1013000";GameObject obj = Resources.Load(filepath) as GameObject;TextAsset xmlAsset = Resources.Load(filepath,typeof(TextAsset)) as TextAsset;XmlDocument xmlDoc = new XmlDocument();xmlDoc.LoadXml(xmlAsset.text);//获取全部子节点;XmlNodeList nodeList = xmlDoc.SelectSingleNode("character").ChildNodes;foreach (XmlNode child in nodeList){if (child.Name == "roleMotions"){m_roleMotions = child as XmlElement;}else if (child.Name == "skills"){m_skills = child as XmlElement;}}Debug.Log("m_roleMotions = " + m_roleMotions.InnerXml);Debug.Log("m_skills = " + m_skills.InnerXml);}}

新建的Xml文档内容例如以下：

<character><roleMotions><motionInfo><motion clipName="enter_ready" isLoop="false" moveEndTime="0" moveStartTime="0" /></motionInfo></roleMotions><skills><skill name="普攻" motion="RMT_Attack1" /></skills>
</character>

读取Xml结果：
