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 initialization

	void Start () {

        //CreateXml();

        //ReadXml();

        ReadFileToXml();

	}

	// Update is called once per frame

	void 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：
