dynamic ContexMenu

Question

Hi! I have a problem. After Click MenuItem header: "System.XML.XMLElement".

Can someone please tell me what I'm doing wrong?

IpLisr.xml

<?xml version="1.0" encoding="utf-8" ?>
<IPList>
  <header Name="1" Click="1" Tag="1">192.168.0.100</header>
  <header Name="2" Click="2">192.168.0.101</header>
  <header Name="3" Click="3">192.168.0.102</header>  
</IPList>

list.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"&gt;
    <XmlDataProvider x:Key="XMLMenu" Source="IPList.xml" XPath="IPList/header"/>    
</ResourceDictionary>

XAML:

<MenuItem Header="IP" DataContext="{StaticResource XMLMenu}" ItemsSource="{Binding}" Click="MenuItem_Click_IP"/>

*.cs

private void MenuItem_Click_IP(object sender, RoutedEventArgs e)
        {
            MenuItem obMenuItem = e.OriginalSource as MenuItem;
            MessageBox.Show(String.Format("{0} just said Hi!", obMenuItem.Header)); 
            //Need header of IPList.xml. How get that? 
        }
