The answer is to use objectforscripting.

See:

http://blogs.msdn.com/b/wpf/archive/2011/05/27/how-does-wpf-webbrowser-control-handle-window-external-notify.aspx

XAML:

<WebBrowser x:Name="HtmlHost" ObjectForScripting="HtmlInteropClass" />

c#

[System.Runtime.InteropServices.ComVisibleAttribute(True)]
Public Class HtmlInteropClass
{
 Public void MyMethod(string SomeValue)
 {

  ((MainWindow)Application.Current.MainWindow).SomeTextBox.Text = SomeValue;
 }
}

Your equivalent would, obviously, new up and show a window instead of that.

Javascript

<script type=”text/javaScript”>
 Function wpfAppMethod(inputValue) {
  Window.external.MyMethod(inputValue);
 }
</script>

I suppose you could pass the name of the window to open as a string.

Edit: If you want to handle the click of an HTML link, you could hook up an event handler to the HTML element once the document has been loaded as described here: https://social.msdn.microsoft.com/Forums/vstudio/en-US/a4f0e4d0-78bf-44c5-a3fe-8faf2e7a0568/handling-link-click-event-of-web-browser-control?forum=wpf

You should be able to open another WPF window in an XBAP using the Show() or ShowDialog() method provided that the application is running in full-trust mode (Properties->Security->This is a full trust application).

Please refer to the following page for more information about how to create and deploy a full-trust XBAP: https://msdn.microsoft.com/en-us/library/vstudio/aa970060(v=vs.100).aspx

Then you could implement an ordinary button click event handler:

    private void Button_Click(object sender, RoutedEventArgs e) {
        Window1 win = new Window1();
        win.Show();
    }
