Unity3d读取XML配置文件

string path = Application.dataPath + @"/Resources/config.xml";

            foreach (XmlNode x in node) {
                    //这儿写个switch去取x.Name判断子节点
                    XmlNodeList child = x.ChildNodes;
                      int count = 0;
                      foreach (XmlElement server in child) {
                    //当我们取到子节点的时候，子节点有属性就需要用XmlElement 去寻找
                }
