Dynamic XML Data Binding

I would like to have a dynamic data binding in my application: if I
press a button, I bind a text box to an XML Data source, and if I press
on another one, I bind it to another XML file... In fact, something
like this function on my Button MouseClickHandler:

private void loadXML1(object sender, System.Windows.RoutedEventArgs e)
{

Binding bind = new Binding();

bind.Source = @"c:\xml\xml1.xml";
bind.XPath="/User/Name";
bind.Mode=System.Windows.Data.BindingMode.Default ;

this.nameTextBox.SetBinding(TextBlock.TextProperty,bind);


}

And another one with the @"c:\xml\xml2.xml" path on my other Button.

It's not working... what should I change?

You need to define an XmlDataProvider[1], specify that instance as the source
of your bindings and then you can change it's Source property in your buttons
and anything bound to it should be updated automatically as the new document
is loaded.

Thanks for the answer, but I really don't know a lot about C# and XAML
and have problems implementing it:
My XmlDataProvider is: <XmlDataProvider x:Key="XMLdb"
d:IsDataSource="True" Source="D:\db_A.xml"/>

In the code behind my button, I don't know how to do in order to change
the source of this XmlDataProvider.
