Getting XML node data into a variable

programming flash
1

Hi, I have a datagrid called dg that has data populated to it thru an external XML. What I am trying to achieve is whenever someone clicks on an item in the grid it stores that items coordinates to a variable called locCoordinates. At this moment it is tracing out all of the items in the grid coordinates I just dont know how to go about getting what I want. Any help is appreciated. I attached a sample of my XML and my AS3 code.

Thanks
