读xml文档中数据并对其进行排序,然后在datagrid中显示出来

1.新建xml文档(books.xml)
<items>
<item>
    <iname>a</iname>
    <iid>1001</iid>
    <iamount>12.34</iamount>
</item>
<item>
    <iname>c</iname>
    <iid>002</iid>
    <iamount>15.38</iamount>
</item>
<item>
    <iname>c</iname>
    <iid>1280</iid>
    <iamount>18.75</iamount>
</item>
<item>
    <iname>e</iname>
    <iid>508</iid>
    <iamount>20.55</iamount>
</item>
</items>

2.编写代码
string dataUrl = "books.XML";
    
            DataSet ds = new DataSet();
            
            ds.ReadXml(Server.MapPath(dataUrl));

            DataView dv = new DataView(ds.Tables[0]);
            
            dv.Sort="iname DESC,iid ASC" ;//默认ASC(ascending)

            //DataTable dt = dv.Table;

            this.DataGrid1.DataSource=dv;
            //this.DataGrid1.DataSource=ds.Tables[0];
            this.DataGrid1.DataBind();
