Xml... x and y position of an swf

xml… x and y position of an swf
I have a photogallery that is loading an external xml , i have 1 pic and 1 swf but the swf doesn’t load correctly , it’s all the way up to the left side.
My question is…can i change the _x and _y position of the swf with xml?
Thanks for the help guys
