我想做一个网上投票系统，采用的是xml存储数据的方式。我的vote.xml文件如下：
<?xml version="1.0" encoding="gb2312">
<newvote>
<vote>
<allvote></allvote>
<verygood></verygood>
<good></good>
<nomal></nomal>
<bad></bad>
</vote>
</newvote>
asp.net页面(vote.aspx)代码如下：
<%@ import namespace="system.xml"%>
<%@ import namespace="system.data.oledb" %>
<%@ import namespace="system.data" %>
<%@ Page Language="VB" debug="true" ContentType="text/html"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<script runat="server">
Sub user_vote(sender As Object, E As commandeventargs)
dim voteds as dataset=new dataset()
voteds.readxml(server.MapPath("image\vote.xml"))
voteds.tables(0).rows(0).item(0)+=1
select case radio1.selecteditem.value
case "1"
voteds.tables(0).rows(0).item(1)+=1
case "2"
voteds.tables(0).rows(0).item(2)+=1
case "3"
voteds.tables(0).rows(0).item(3)+=1
case "4"
voteds.tables(0).rows(0).item(4)+=1
end select
voteds.writexml(server.MapPath("image\vote.xml"))
votelabel.style("color")="red"
votelabel.text="投票成功！"
End Sub
</script>
<body>
<form runat="server">
<table align="center">
<tr><td align="center">网站调查</td></tr>
<tr><td>你觉得这个站点怎么样</td></tr>
<tr><td>
<asp:RadioButtonList ID="radio1" runat="server">
<asp:listitem Value="1" selected>很好</asp:listitem>
<asp:listitem value="2">好</asp:listitem>
<asp:listitem value="3">一般</asp:listitem>
<asp:listitem Value="4">差</asp:listitem>
</asp:RadioButtonList>
</td></tr>
<tr><td><br></td></tr>
<tr><td align="center"><asp:Button ID="toupiao" runat="server" commandname="vote123" Text="投票" oncommand="user_vote"/><asp:Button ID="chakan" runat="server" Text="查看" /></td></tr>
<tr>
<td align="center"><asp:label id="votelabel" runat="server"></asp:label></td>
</tr>
</table>
</form>
</body>
</html>
