I'd like to organize my XML data to be collapsable and expandable using a preprocessor command like the #region/#endregion command in C#/.NET. I'm editing this file Visual Studio 2008.

Does any such ability exist? I've googled to no avail. The closest I can come to so far is to expand and collapse the tags themselves, so I can collapse between 

<Data> 
(this is collapsed)
</Data>
c# xml visual-studio-2008 region
