datalist绑定xml文件

我有一个xml文件: play.xml
<music>
<Entry>
  <Title>千里之外 - 周杰伦</Title>
  <Ref href="http://www.lzpcc.com.cn/268316.wma" />
</Entry>
<Entry>
  <Title>听妈妈的话 - 周杰伦</Title>
  <Ref href="http://wma.1ting.com/wmam/2.wma" />
</Entry>
</music>
怎样把这个文件邦定到DataList上呢?并对它进行编辑,删除,添加操作.对应的是:

歌曲名称                   地址                                           操作
千里之外 - 周杰伦        http://www.lzpcc.com.cn/268316.wma /    编辑  删除  添加
听妈妈的话 - 周杰伦     http://wma.1ting.com/wmam/2.wma"  /      编辑  删除  添加

http://net.stuun.cn/program/ASPnet/shili/35715.html里面有个例子，搂住可以参考以下，希望对你有帮助
DataSet dst = new DataSet();
dst.ReadXml(@"C:\play.xml");
datalist.datasource = dst;这样行不?没试过,嘻~~~
用XmlDocument 解析        XmlDocument doc = new XmlDocument();
        doc.Load(Server.MapPath("play.xml"));
        XmlNodeList nodes = doc.SelectNodes("//Ref");
        foreach (XmlNode node in nodes)
        {
            XmlElement elem = (XmlElement)node;
            XmlAttribute attr = elem.GetAttributeNode("href");
            Response.Write(attr.InnerText+"<br/>");
        }可以取出Ref结点的属性绑定自己可以构造
或者使用DataSet.ReadXml将xml读入到dataset中
你把下面的代码改为c#   ''' <summary>
    ''' 根据XML文件返回表
    ''' </summary>
    ''' <param name="path">路径</param>
    ''' <returns></returns>
    ''' <res></res>
    Public Function getdata(ByVal path As String) As DataView
        Dim dt As DataTable = New DataTable()
        Dim dv As DataView = New DataView()
        Dim stream As FileStream = New FileStream(Server.MapPath(path), FileMode.Open)
        Dim doc As XmlDataDocument = New XmlDataDocument
        doc.DataSet.ReadXml(New StreamReader(stream))
        dt = doc.DataSet.Tables(0)
        dv = dt.DefaultView
        stream.Close()
        Return dv
    End Function
XmlDataDocument xmlDoc = new XmlDataDocument();
DataSet xmlDataSet;
//将Dataset与xmldoc关联
xmlDataSet = xmlDoc.DataSet;
//读取xml 文件,同时xmldataset也可读入相应的数据
xmlDoc.Load("play.xml");然后再将xmldataset的值显示到datalist中.
正巧这些天也在学XML,帮LZ写了一个看

恩，遇到过同样的问题，用gridview之类的不好使，最后还是xmldocument+xpath
