怎么遍历-<RoomRates>
- <RoomRate>节点下的值.当输入时期等于EndDay>20080501</EndDay>跳到下个节点. 

解决方案 »

  1.   

    xml.readdataset,
    xml直接读成dataset
      

  2.   

    我给你一段代码你研究下.        XmlDocument xml = new XmlDocument();
            string xmlpath = path;   // path是XML的文件路径
            xml.Load(xmlpath);
            XmlNode xn = xml.DocumentElement.SelectSingleNode(" RoomQuotas") 
            XmlNodeList nodes = xn.SelectNodes("RoomQuota");
            foreach (XmlNodeList no in nodes)     //读取每一个RoomQuota
            {
                 XmlElement xe=(XmlElement)no;
                 XmlNodeList nodes1=xe.ChildNodes
                 foreach(XmlNode no1 in nodes1)   //读取RoomQuota中的所有属性
                        {
                          XmlElement xe2=(XmlElement)no1;   //转换类型
                            if(xe2.GetAttributeNode(EndDay).InnerText=="20080501 ")//如果找到EndDay的值为20080501 好象是这么写.
                            {                        XmlNode no3= xe.SelectNodes("following-sibling::RoomQuota[1]";  //取下一个RoomQuota的XmlNode
                            想做什么操作随意吧.
                                break;                        }
                        }        }
    基本就是这些,有什么问题找我.
      

  3.   

    上面的 XmlNode no3= xe.SelectNodes("following-sibling::RoomQuota[1]";  
    也可以改成
     xe.NextSibling
      

  4.   

    恩.谢谢. .我试下. 但是这个XML是动态的..    试好结分
      

  5.   

    XmlElement xe=(XmlElement)no;
     
     转换有错!
