　　asp.net 2.0提供了多種數據源，一般情況下，xmldatasource控件使用xml文件，下面的例子就是使用xmldocument對象進行數據綁定的一種方法。

　　vb.net代碼

<%@ 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="文章標題">
          <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#代碼

<%@ 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="文章標題">
          <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>
