XMLDataSource and Repeater

Hello,

I'm trying to bind an xmldatasource to Repeater. The XMLDatasource contains 31 items.
When i try to display the following result (see below) and while setting the ContentType of the page to "text" I get the 31 items. But when I set to "text/xml" I only receive 6 items.

Any idea why I'm not being able to get the 31 items ?

Code:
