jQuery Grid Plugin - jqGrid

Is is possible to have the grid automatically laid out based on XML or JSON? Lets say, I have allot of different pages so I would not be working from the same declared grid. I want the grid to load and display based on XML. Is there a method or function

ColModel.BasedOnXML (Example)

Or something of that nature? If Column titles would just be the element name or whatever. 🙂 Just would like to lay these grids out without having to keep making column models.
