XmlHelper操作Xml文件 根据Xml地址得到Xml内容

XmlHelper操作Xml文件

根据Xml地址得到Xml内容,可自定义缓存

XmlHelper使用教程：

        //用法
        /*
          XmlDocument xml = getXml(HttpContext.Current.Server.MapPath("~/qqq/sion.xml"), true);
                    XmlNode node = null;
                    if (type == "android")
                    {
                        node = xml.DocumentElement.SelectSingleNode("type[@name='oid']");
                    }
         * 
         *  HttpUtility.UrlPathEncode(node.Attributes["url"].Value)
         
         */
