How I can binding specified xml node to datagridview?

Question

hello
please, i am new in c#;
I have xml file, i displayed the first node within form in c#, this node have attribute is called 'id', now i want to display all nodes that have attribute is called 'father' its value equal to id value of the displayed node.
xml file:
<?xml version="1.0" encoding="UTF-8"?>
<tree>
<grand name="aaa" id="1" sex="m" status="d" child="2" father=""></grand>
<grand name="ddd" id="12" sex="m" status="d" child="" father="1"></grand>
<grand name="bbb" id="11" sex="m" status="d" child="1" father="1"></grand>
<grand name="ccc" id="111" sex="m" status="d" child="1" father="11"></grand>
<grand name="ddd" id="1111" sex="m" status="d" child="3" father="111"></grand>
<grand name="eee" id="11111" sex="f" status="d" child="" father="1111"></grand>
<grand name="fff" id="11112" sex="m" status="d"child="" father="1111"></grand>
</tree>
c# code that display the first node is:
InitializeComponent();
XDocument xdoc = XDocument.Load(" http://domaim.net/tree/index.xml");
var name = xdoc.Descendants("grand").First().Attribute("name").Value;
var sex = xdoc.Descendants("grand").First().Attribute("sex").Value;
var alive = xdoc.Descendants("grand").First().Attribute("status").Value;
var child = xdoc.Descendants("grand").First().Attribute("child").Value;
var id = xdoc.Descendants("grand").First().Attribute("id").Value;
var father = xdoc.Descendants("grand").First().Attribute("father").Value;
textBox1.Text = name;
if (sex == "m") textBox2.Text = "male"; else textBox2.Text = "female";
if (child == "") textBox4.Text = "no child"; else textBox4.Text = child;
if (alive == "d") textBox3.Text = "dead"; else textBox3.Text = "alive";
here I displayed  the node its id="1", now i want to display all nodes that its "father" attribute is equal 1. i want to display thier attributes of these nodes within datagridview,(bbb & ddd).
thank you for all.

Try this.  You have an error in the XML that you need to put a space before child in the last row.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
public partial class Form1 : Form
public Form1()
InitializeComponent();
DataSet ds = new DataSet();
ds.ReadXml(@"c:\temp\index.xml");
dataGridView1.DataSource = ds.Tables["grand"];
DataTable fatherRows = ds.Tables["grand"].AsEnumerable()
.Where(x => x.Field<string>("father") == "1").CopyToDataTable();
dataGridView2.DataSource = fatherRows;
