Items not showing in WPF ListBox even though they show up in design mode

Question

I'm having some problems with data binding in XAML and WPF. Specifically, I'm trying to bind data from an XmlDataProvider to a ListBox.

The problem is this, when I'm in design mode in Visual Studio 2010, the xml items show up correctly, but when I run the app the listbox is just empty.

Here is what my xaml looks like. I'm not using any code behind, so this is all there is:

<Window x:Class="WpfTest9_Binding.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="309" Width="622">
    <Window.DataContext>
        <XmlDataProvider XPath="Servers">
            <x:XData>
                <Servers>
                    <Server name="Server01" active="true" />
                    <Server name="Server02" active="false" />
                    <Server name="Testserver01" active="true" />
                    <Server name="Testserver02" active="true" />
                </Servers>
            </x:XData>
        </XmlDataProvider>
    </Window.DataContext>
    <Grid>
        <ListBox ItemsSource="{Binding XPath=*}" Margin="12">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Border CornerRadius="5" Margin="5" BorderThickness="2" BorderBrush="#FFC14343">
                        <StackPanel Orientation="Horizontal" Margin="5">
                            <CheckBox IsChecked="{Binding XPath=@active}" />
                            <Label Content="{Binding XPath=@name}" />
                        </StackPanel>
                    </Border>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>
</Window>

Like I said above, the strange thing is that it looks like it's working while in design mode, but it fails to fill the listbox when I run the application. I'm not getting any error messages or warnings either.

What's wrong?

Ok, the solution was surprisingly simple. As pointed out in this post, Listbox content not being populated with content from xml when using XmlDataProvider , all I had to do was to add an empty namespace attribute to the xml element. Like this:

<Servers xmlns="">
    <Server name="Server01" active="true" />
    <!-- ... -->
</Servers>
