FOR XML PATH + File Structure

Hey there,

I used the FOR XML PATH feature but the XML result is in only one line,
it does not conserve the XML structure (treeview). When I open the XML
file with IE, it s working very (I have the XML hierarchy) but when I
use Visual Studio or other tool to edit it, I ve just one line!

For example:
<children group=""><child firstname="" lastname=""></child>=""><child
firstname=""
lastname=""></child>..............................</children>............

And I d like to have
<children group="">
<child firstname="" lastname=""></child>="">
<child firstname="" lastname=""></child>
..............................
</children>
..............

To give you an example of the query:

SELECTChild.group AS '@group',

(SELECT firstnameAS '@firstname',
lastnameAS '@lastname'

FROM Collecte_Data_Extract cde

FOR XML PATH('child'), TYPE)

FROM Feed AS Child
FOR XML PATH('children'), TYPE

Any idea?
Many thanks in advance
