我想把xml文件中的内容读到datagrid中去，请问如何实现？
如
authors.xml:
<Authors>
<Author>
<name>Mark</name>
<price>2200</price>
</Author>
<Author>
<name>Jane</name>
<price>3500</price>
</Author>
<Author>
<name>Tom</name>
<price>4000</price>

用ReadXml把文件读到数据集里，然后再和datagrid绑定:

<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Data" %>

<html>

<script language="C#" runat="server">

protected void Page_Load(Object Src, EventArgs E) {
DataSet ds = new DataSet();

FileStream fs = new FileStream(Server.MapPath("authors.xml"),FileMode.Open,FileAccess.Read);
StreamReader reader = new StreamReader(fs);
ds.ReadXml(reader);
fs.Close();

DataView Source = new DataView(ds.Tables[0]);

MyLiteral.Text = Source.Table.TableName;
MyDataGrid.DataSource = Source;
MyDataGrid.DataBind();
}

</script>

<body>

<h3><font face="宋体">表的 XML 数据：<asp:Literal id="MyLiteral" runat="server" /></font></h3>

<ASP:DataGrid id="MyDataGrid" runat="server"
Width="900"
BackColor="#ccccff"
BorderColor="black"
ShowFooter="false"
CellPadding=3
CellSpacing="0"
Font-Name="宋体"
Font-Size="9pt"
HeaderStyle-BackColor="#aaaadd"
EnableViewState="false"
/>

</body>
</html>

我的代码是这样，来看看分析：
XmlDocument xml_xdoc=new XmlDocument ();
xml_xdoc.Load (Server.MapPath ("authors.xml"));
XmlNode xml_node=xml_xdoc.DocumentElement;
DataSet tempds=new DataSet ();
if (xml_node.NodeType ==XmlNodeType.Text )
{
XmlElement el = (XmlElement)xml_xdoc.SelectSingleNode("name");
tempds.ReadXml(el.InnerText);
}
this.DataGrid1.DataSource =tempds ;
this.DataGrid1.DataBind ();

错误消息如下：
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code
System.Web.HttpException: The IListSource does not contain any data sources
错误指向：this.DataGrid1.DataBind ();
为什么？
