DataGrid 绑定 xml 的有关问题

DataGrid 绑定 xml 的问题
XmlDocument   dom   =   new   XmlDocument();
dom.LoadXml(usersxml);
dom.Save( "d:/userxml.xml ");
dom.RemoveAll();
DataSet   ds   =new   DataSet();
ds.ReadXml( "d:/userxml.xml ");
this.DataGrid1.DataSource   =   ds.Tables[0];
this.DataGrid1.DataBind();

什么都没读出来

其实只是想取得   一列就行     每个 <user> 里的 <param   name= "realname "   value= "陈立军 "   /> 这个

也换了种写法     可也没显示出   数据     求XDJM们帮帮忙看下~~~谢谢  


XmlNodeList     nodes   =   dom.SelectNodes( "orgUnit/user/param[@name= 'realname '] ");
if(nodes!=null)
{
  foreach   (XmlNode   node   in   nodes)
  {
    DataTable   dt   =   new   DataTable();
    dt.Columns.Add( "name ",Type.GetType( "System.String "));

    dt.Columns.Add(node.Attributes[ "realname "].Value);
    this.DataGrid1.DataSource=dt;
    this.DataGrid1.DataBind();
}


---------------------
上面的程序也   显示不出数据~~~

下面是我的XML格式及内容

分不够再加     请帮帮忙~~~

[解决办法]
this.DataGrid1.DataSource = ds.Tables[0].DateView;

[解决办法]
你取出XML已经到DataSet中了，可以直接用DataTable的Select方法查找出你要的数据，再绑定不就行了。
[解决办法]
第二种的写法不对，应该是：

XmlNodeList nodes = dom.SelectNodes( "orgUnit/user/param[@name= 'realname '] ");
if (nodes != null)
{
DataTable dt = new DataTable();
dt.Columns.Add( "name ", Type.GetType( "System.String "));
foreach (XmlNode node in nodes)
{
DataRow row = dt.NewRow();
row[ "name "] = node.Attributes[ "value "].Value;

dt.Rows.Add(row);

}
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
