Parse XML in SilverLight 4.0

Step1) Create Silverlight Applicatication using .NET 4.0

Step 2)  Add new Order class in Silverlight Project.


File Name:  Order.cs

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SilverlightApplication3

{

    public class Order

    {

        private string OrderID, Amount, Qty, Product,Total;

        public string PRODUCT

        {

            get { return Product; }

            set { Product = value; }

        }

        public string ORDERID

        {

            get { return OrderID; }

            set { OrderID = value; }

        }

        public string AMOUNT

        {

            get { return Amount; }

            set { Amount = value; }

        }

        public string QTY

        {

            get { return Qty; }

            set { Qty = value; }

        }

        public string TOTAL

        {

            get { return Total; }

            set { Total = value; }

        }

    }

}

Step 3)  Drag & Drop Label and DataGrid in MainPage.xaml

XAML excert 

    <Grid x:Name="LayoutRoot" Background="White">

        <sdk:DataGrid AutoGenerateColumns="True" Height="156" HorizontalAlignment="Left" Margin="10,51,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="390" />

        <sdk:Label Height="58" HorizontalAlignment="Left" FontSize="16" Margin="10,10,0,0" Name="label1" VerticalAlignment="Top" Width="378" Content="Silverlight XML Source in DataGrid" Foreground="#FFBE2C2C" FontWeight="Bold" FontStyle="Italic" />

    </Grid>

Step 4) Open MainPage.XAML.cs

Add following code

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

namespace SilverlightApplication3

{

    public partial class MainPage : UserControl

    {

        List<Order> ordList = new List<Order>(); //Declare list of Orders

        public MainPage()

        {

            InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainPage_Loaded);

        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)

        {

//Declare  inline XML or it can be generic handler emiting xml from other website

            String xmlString =

                @"<?xml version='1.0'?>

                  <Orders>

                   <Order>

                       <ID>1</ID>

                        <Product>Cloths</Product>

                        <Amount>1500</Amount>

                        <Qty>10</Qty>

                    </Order>

                   <Order>

                       <ID>2</ID>

                        <Product>Shoes</Product>

                        <Amount>15000</Amount>

                        <Qty>20</Qty>

                    </Order>

                    </Orders>

                ";

            //Read xml--> element by element

            //Samething can be done  using LINQ to XML.

            //Silverlight doesnot support  XPathNavigator. 

            System.Text.StringBuilder output = new System.Text.StringBuilder();

            using (System.Xml.XmlReader reader =

                System.Xml.XmlReader.Create(new System.IO.StringReader(xmlString)))

            {

                while (reader.Read())

                {

                    Order o = new Order();

                    reader.ReadToFollowing("ID");

                    o.ORDERID = reader.ReadInnerXml();

                    //output.Append("ID=" + reader.ReadInnerXml());

                    reader.ReadToFollowing("Product");

                    o.PRODUCT = reader.ReadInnerXml();

                    //output.Append("Product=" + reader.ReadInnerXml());

                    reader.ReadToFollowing("Amount");

                    o.AMOUNT = reader.ReadInnerXml();

                    //output.Append("Amount=" + reader.ReadInnerXml());

                    reader.ReadToFollowing("Qty");

                    o.QTY = reader.ReadInnerXml();

                    //output.Append("Qty=" + reader.ReadInnerXml());

                    if (!String.IsNullOrEmpty(o.AMOUNT))

                    {

                        o.TOTAL = (Int16.Parse(o.AMOUNT) * Int16.Parse(o.QTY)).ToString();

                        ordList.Add(o); //Add to OrderList

                    }

                }

                dataGrid1.ItemsSource = ordList; //Assign it to DataGrid Item Source

            }

            

        }

    }

}

Step 5)  Run the Applictaion/F5
