getChild(name)

    public class SaveXML
{
    public static void SaveData(object obj, string filename)
    {
        XmlSerializer sr = new XmlSerializer(obj.GetType());
        XmlSerializer rs = new XmlSerializer(obj.GetType());
        TextWriter writer = new StreamWriter(filename);
        sr.Serialize(writer, obj);
        writer.Close();
    }
}

 public class Products
{
    private string DatePick;
    private string name;
    private string category;
    private string volume;
    private string volunit;
    private string quantity;
    private string purprice;

    public Products() { }
    public Products(string DatePick, string name, string category, string volume, string volunit, string quantity, string purprice, string sellprice)
    {
        this.DatePick = DatePick;
        this.name = name;
        this.category = category;
        this.volume = volume;
        this.volunit = volunit;
        this.quantity = quantity;
        this.purprice = purprice;
        this.sellprice = sellprice;
    }
