dual porting PyQt widget contents and/or python variables into a xml dom tree?

i've got an application where i have lot of various PyQt widgets that
i would like to "dual port" into a xml dom tree node that i define at widget creation time.
In other words,
- whenever a widget changes value i'd like a node in the dom tree to
get updated with the new value of the widget (whatever that may be).
- similarly, i'd like the widget to be updated
anytime some part of the program alters the widgets
associated dom node.
i could sublass every PyQt widget in the universe and put the dual porting code
where needed. I would guess this involves setting up one or more reciprocal signal/slot connections between the widget and some kind of xml dom object.
This approach seems a bit heavy handed though..
Has Anybody else out there had the same need but found a simpler, way to accomplish this feat?
Doing something this is pretty easy in tcl/tk with variable
traces etc.. Is there something comparable to variable traces in python?
