As everyone else said, you should have first try to find answer by searching in Google or even stackflow itself might have guided you.

Anyway,

XmlDocument xDoc = new XmlDocument(); 
xDoc.Load("XMLFile.xml")");  
XmlNodeList nodeList; 
nodeList = xDoc.DocumentElement.SelectNodes("Bathing");

foreach (XmlNode node in nodeList)

{

XmlNode child = node.SelectSingleNode("Id");

child.InnerText = "NewValue";

..write for other child nodes...

}
