这种怎么读取，我想先读取root下的所有project节点  在页面上展示“熙街一期"，"熙街二期"等用table 或者用repeater控件展示在通过点击”一期“或则其他进入另一个页面显示下一节点然后在读取building 节点展示在点击 --------------------编程问答-------------------- 用dataset或者xmldatadocument都可以对xml进行读取。 --------------------编程问答-------------------- XmlDocument xml = new XmlDocument();
xml.Load("XXXX.xml");
XmlNodeList xmlNodeList = xmlLoad.SelectNodes("root/project [id='1']");//查找root下 id=1的节点
XmlNode xmlNode = xmlNodeList.Item(0);
string txt = xmlNode["name"].InnerText;//显示东大楼 --------------------编程问答-------------------- 最简单的，datatable  aa= xx.readXml(); --------------------编程问答-------------------- 你可以参考类似的方法
