Unity读取XML

先发两个Google到的东西：

事实上就是可以用.net带的XML解析库来解析。但是如果在web上发布就要带上这个库，会增加1M的资源，所以官方推荐另一个库。

官方的说法：

本来用WWW来寻址。。结果发现一导出android的APK包，就找不到相对地址了。。于是用了Resource文件夹来存放资源。

using System.Xml;

public void LoadGoodsFromXML(string fileName)
{
//www = new WWW("file://"+Application.dataPath+"/xml/"+fileName);

//while (www.isDone != true);

//Debug.Log(www.url);

string data = Resources.Load(fileName.Split('.')[0]).ToString();

XmlDocument xmlDoc = new XmlDocument();

//while(www.isDone != true);

xmlDoc.LoadXml(data);

XmlNodeList nodeList = xmlDoc.SelectNodes("Fridge/Units/Unit");
numGoods = nodeList.Count;
Debug.Log(numGoods);

Goods good;
int numCount;
foreach (XmlNode node in nodeList)
{
good  = new Goods();
good.name = node.SelectSingleNode("Name").InnerText;
Debug.Log(good.name);
//www = new WWW("file://"+Application.dataPath+"/Images/VegetableShop/"+node.SelectSingleNode("IconID").InnerText);
good.texture = (Texture2D)Resources.Load(node.SelectSingleNode("IconID").InnerText.Split('.')[0]);
numCount = int.Parse(node.SelectSingleNode("Num").InnerText);
goodsList.Add(good);
goodsNumMap.Add(good.name, numCount);
}

}
