Sort Combobox Items

Hi.

I have a combo box created using xaml. I bind the item source to a xml document.

<ComboBox Name="cb1" ItemsSource="{Binding Source={StaticResource myList}, XPath=Items/Item}" DisplayMemberPath="Name"/>

I would like to sort the combobox items so that the items are displayd in ascending order.  

I manage to sort the above list by using SortDescription as below :

SortDescription sd = new SortDescription("Name", ListSortDirection.Ascending);

cb1.Items.SortDescriptions.Add(sd);

The combobox will display the items in the following order.

Now, when I add a node to the xml document, I added CData to handle invalid characters. The xml document will be updated as below :

>Name>

When I do this, the sorting failed. The node with CData is always sorted to the top of the list.

Any idea what I can do to solve this problem?

Thanks.
