Using XML gives you portability at the expense of increased code 
manipulating the data structures.

Try creating a button with "<<<" as the label and you'll find why your xml 
solution isn't ideal. For anything non-trivial you'll find it much better 
to use one of the existing xml libraries to build your xml and then you'll 
find why the non-xml solution looks simpler.

Generally speaking you make the decision to use xml or not based on a lot 
of factors. Sometimes it is the best solution, other times using something 
like a Python pickle might be better. Use whichever you are happy with 
here.
