1.xml文件内容如下：

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

<info>

<book id ="b1" lang ="en">

<name>c++</name>

<price>555</price>

</book>

<book id ="b2" lang ="en">

<name>c#</name>

<price>666</price>

</book>

</info>

这个文件可以放在resources或者StreamingAssets这个下面，所以有了两种路径读取方式，读取方式如下

using UnityEngine;

using System.IO;

using System.Xml;

using System.Collections;

public class ReadXml : MonoBehaviour {

/// <summary>

/// resources下面读取xml的方法

/// </summary>

//void Start()

//{

// //resources下面的读法

// TextAsset textAsset = Resources.Load("XMLFile1", typeof(TextAsset)) as TextAsset;

// ReadXML(new MemoryStream(textAsset.bytes));

//}

/// <summary>

/// StreamingAssets 下面的读取xml的方法

/// </summary>

/// <returns></returns>

IEnumerator Start()

{

WWW www = new WWW("file://" + Application.streamingAssetsPath + "/XMLFile1.xml");

yield return www;

ReadXML(new MemoryStream(www.bytes));

www.Dispose();

}

// Update is called once per frame

void Update ()

{

}

void ReadXML(Stream stream) {

XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(stream);

XmlNode info = xmlDoc.SelectSingleNode("info");

foreach (XmlNode node in info.ChildNodes)

{

string id = node.Attributes["id"].InnerText;

string lang = node.Attributes["lang"].InnerText;

string name = node.SelectSingleNode("name").InnerText;

Debug.Log(node.Name + "/" + "id =" + id + " lang = " + lang + " name = " + name);

}

}

}
