　　ASP.NET 2.0提供了多种数据源，一般情况下，XmlDataSource控件使用XML文件，下面的例子就是使用XmlDocument对象进行数据绑定的一种方法。

　　VB.NET代码

<% Page Language="VB" %>
<script runat="server">
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim doc As New System.Xml.XmlDocument
    doc.Load("http://dotnet.aspx.cc/Rss.aspx")
    XmlDataSource1.Data = doc.InnerXml
    XmlDataSource1.XPath = "/rss/channel/item"
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
    <asp:GridView ID="GridView1" runat="server" DataSourceID="XmlDataSource1" AutoGenerateColumns="false">
      <Columns>
        <asp:TemplateField HeaderText="文章标题">
          <ItemTemplate>
            <asp:HyperLink runat="server" Target="_blank" NavigateUrl='<%#XPath("link") %>'>
            <%#XPath("title")%></asp:HyperLink>
            [<%#CType(XPath("pubDate"), DateTime).ToString("yyyy年M月d日")%>]
          </ItemTemplate>
        </asp:TemplateField>
      </Columns>
    </asp:GridView>
    <asp:XmlDataSource ID="XmlDataSource1" runat="server"></asp:XmlDataSource>
</form>
</body>
</html>

　　C#代码

<% Page Language="C#" AutoEventWireup="true"%>
<script runat="server">
protected void Page_Load( object sender, System.EventArgs e )
{
    System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
    doc.Load("http://dotnet.aspx.cc/Rss.aspx");
    XmlDataSource1.Data = doc.InnerXml;
    XmlDataSource1.XPath = "/rss/channel/item";
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
    <asp:GridView ID="GridView1" runat="server" DataSourceID="XmlDataSource1" AutoGenerateColumns="false">
      <Columns>
        <asp:TemplateField HeaderText="文章标题">
          <ItemTemplate>
            <asp:HyperLink ID="HyperLink1" runat="server" Target="_blank" NavigateUrl='<%#XPath("link") %>'>
            <%#XPath("title")%></asp:HyperLink>
            [<%#(DateTime.Parse(XPath("pubDate").ToString().Replace("GMT",""))).ToString("yyyy年M月d日")%>]
          </ItemTemplate>
        </asp:TemplateField>
      </Columns>
    </asp:GridView>
    <asp:XmlDataSource ID="XmlDataSource1" runat="server"></asp:XmlDataSource>
</form>
</body>
</html>
