Read XML in Silverlight

Posted by Viral Sarvaiya on August 25, 2010

XML is an important medium in the world of Silverlight especially where Web Services are involved.  The .NET 3.5 that comes with Silverlight omits some of the core XML objects that you will find in the full incarnation of .NET 3.5.  There is however the XML Reader and Writer classes that allow you high speed access to reading and writing XML documents.  In our sample on this page we use an XML reader to read a simple XML file and render the results to the page.

Our example XML file looks like this, as you can:

<?xml version="1.0"?>
 <customer id="10001" first="John" last="Smith" company="Donuts plc"></customer>
 <customer id="10002" first="Rete" last="Bandy" company="This Is Bloggers Co."></customer>
 <customer id="10003" first="James" last="Bird" company="Timestone"></customer>
 <customer id="10004" first="Sarah" last="McCauly" company="Automated Snowmen Ltd"></customer>
 <customer id="10005" first="Pete" last="Rowan" company="Cooltec Consultants"></customer>

Now add a Listbox to usercontrol

<UserControl x:Class="XMLTutorial.Page"
 Width="400" Height="300">
 <Grid x:Name="LayoutRoot" Background="White">
 <ListBox x:Name="customersList" Width="400" Height="200" />
Now in usercontrol’s C# file
public partial class Page : UserControl
 public Page()


 private void PopulateCustomersList()
 XmlReaderSettings settings = new XmlReaderSettings();
 settings.XmlResolver = new XmlXapResolver();
 XmlReader reader = XmlReader.Create("Customers.xml");


 while (reader.Read())
 if (reader.NodeType == XmlNodeType.Element && reader.Name == "customer")
 customersList.Items.Add(new ListBoxItem() { Content = reader.GetAttribute("last") +
 ", " + reader.GetAttribute("first") + " (" + reader.ReadInnerXml() + ")" });

 if (reader.NodeType == XmlNodeType.EndElement && reader.Name == "customers")

Enjoy Coding…….
