unity3d使用Mono.Xml读取xml

unity3d读取xml有好几种方式，最简单是直接利用System.Xml读取xml，但是项目打包会比较大，增加了1M的资源占用。另外两个是利用其他轻量级xml库来实现，如Mono.Xml、XMLParser。Mono.Xml是c#写的，XMLParser是js写的。文章主要说明Mono.Xml的用法。
为什么不建议使用System.Xml，unity的解释如下：
When building a player (Desktop, Android or iOS) it is important to not depend on System.dll or System.Xml.dll. Unity does not include System.dll or System.Xml.dll in the players installation. That means, if you want to use Xml or some Generic containers which live in System.dll then the required dlls will be included in the players. This usually adds 1mb to the download size, obviously this is not very good for the distribution of your players and you should really avoid it. If you need to parse some Xml files, you can use a smaller xml library like this one Mono.Xml.zip. While most Generic containers are contained in mscorlib, Stack<> and few others are in System.dll. So you really want to avoid those.

首先，定义一个xml文件，如下：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ROOT>
<table wave="1" level="1" name="John"/>
<table wave="2" level="1" name="Lucy"/>
</ROOT>把Mono.Xml加进unity3d项目。下载地址：http://download.csdn.net/detail/cwqcwk1/7105071
unity3d利用Mono.xml读取xml的代码如下：
using UnityEngine;
using System.Collections;

using Mono.Xml;
using System.IO;

using System.Security;

public class XmlLorder {

public void Read()
{
SecurityParser SP = new SecurityParser();

// 假设xml文件路径为 Resources/test.xml
string xmlPath = "test";

SP.LoadXml(Resources.Load( xmlPath ).ToString());

SecurityElement SE = SP.ToXml();

foreach (SecurityElement child in SE.Children)
{
//比对下是否使自己所需要得节点
if(child.Tag == "table")
{
//获得节点得属性
string wave = child.Attribute("wave");
string level = child.Attribute("level");
string name = child.Attribute("name");
Debug.Log("wave:" + wave + " level:" + level + " name:" + name);
}

}

}

}
顺带提一下unity3d使用XMLParser读取xml：
XMLParser xmlparse = new XMLParser();
XMLNode node = xmlparse.Parse(xmldata.text);

XMLNodeList list = node.GetNodeList("ROOT>0>table");
for (int i = 0; i < list.Count; i++)
{

string wave = node.GetValue("ROOT>0>table>" + i + ">@wave");
string level = node.GetValue("ROOT>0>table>" + i + ">@level");
string wait = node.GetValue("ROOT>0>table>" + i + ">@wait");
