How to set a node ?

Hi everybody.
	I wrote the following code:

	define wd ui.window	
            define nd om.DomNode

	let wd = ui.window.getCurrent()
	let nd = wd.getNode()
            call nd.writeXML("teste.xml")


	the result, as expected, it is a XML file "describing" the current form. I wonder if it is possible to reload this xml into the current window, later on my program. I've been reading Genero documentation but I really can't figure out how. Can somenone give me a hint ?

	TIA
