XML的两种读取方法

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);
}
}
}
