xml文件如上。现在是如何查询和读取里面的字段。

代码如下：这里显示了2个特性。第一是XElement是Xml里面的元素，第二是Attribute是元素里面的属性。Linq查询返回的是IEnumerable接口。Attribute是个键值对关系的属性。通常我们取的是元素某属性的值

 private string _name;
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        private void bindXml()
        {
            string xmlUrl = "PeripheralFlag.xml";

            XElement root = XElement.Load(Server.MapPath(xmlUrl));
            IEnumerable attribNames = from el in root.Elements("Province")
                                      where el.Attribute("ChineseName").Value.Equals(txtInput.Text.Trim())
                                      select el;
            foreach (XElement attribName in attribNames)
            {
                _name = attribName.Attribute("Url").Value;
                lbResult.Text += _name;
            }
        }

        protected void btnSumbit_Click(object sender, EventArgs e)
        {
            lbResult.Text = "";
            bindXml();
        }
    }
