Reverse row order from xml

Hi, I was playing around with loading an XML file into a grid, and was wondering if there was anyway to have the grid show the first element last. (ie. the last entry in the xml file)...

Basically just reversing the order in which rows are displayed... 1 2 3 becomes 3 2 1.

obj.setRowIndices([2,1,0]);
