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. 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="bbb"  id="11" sex="m" status="d" child="1" father="1"   ></grand>
