XML

I have an XML file and i want to make a data table and bind it in grid view , but the data must taken from the XML file according to attributes not the tag
the first attribute is "m" and it represents the row index, the other attribute is "s" and it represents the column index
if the attribute doesn't mentioned in some tags the default value for it is "1"

the outputs must shown in gridview like this form

<asp:GridView id="grdBank" runat="server" AutoGenerateColumns="False" CellPadding="0" >
                               <Columns>

                                   <asp:BoundField HeaderText="Repay date" DataField="repay">
                                       <HeaderStyle Font-Bold="True"></HeaderStyle>
                                   </asp:BoundField>

                                      <asp:BoundField HeaderText="Interest" DataField="interest">
                                       <HeaderStyle Font-Bold="True"></HeaderStyle>
                                   </asp:BoundField>

                                <asp:BoundField HeaderText="Penalty interest" DataField="penalty_interest">
                                       <HeaderStyle Font-Bold="True"></HeaderStyle>
                                   </asp:BoundField>

                               <asp:BoundField HeaderText="Penalty spread" DataField="penalty_spread">
                                       <HeaderStyle Font-Bold="True"></HeaderStyle>
                                   </asp:BoundField>

                               <asp:BoundField HeaderText="Others (CE+CS)" DataField="others">
                                       <HeaderStyle Font-Bold="True"></HeaderStyle>
                                   </asp:BoundField>

                               </Columns>
                             </asp:GridView>

What I have tried:

I tried this code

XmlTextReader reader = null;
          DataTable Items = new DataTable();
                     Items.Columns.Add("repay");
                     Items.Columns.Add("interest");
                     Items.Columns.Add("penalty_interest");
                     Items.Columns.Add("penalty_spread");
                     Items.Columns.Add("others");
                     DataRow dr=Items.NewRow();
         try
 {

    //Load the reader with the XML file.
    reader = new XmlTextReader("attrs.xml");

    //Read the m attribute.
    reader.MoveToContent();

              for (int i = 0; i < reader.AttributeCount; i++) {
    string m = reader.GetAttribute("m");

          dr["repay"]= Convert.ToString(new Random().Next(5, 55));
         //dt.Rows.Add(row1);

    //dr[AttName] = reader.Value;
              }


  }



  finally
  {
     if (reader != null)
       reader.Close();
   }
