How best to dynamically define methods (and functions)?

I can see an obvious but hacky way to define a Python function at
runtime. I can't see any obvious way to add a method to a class at
runtime (though I'm sure one could do just about anything by digging
into the metaclass stuff, which I will do if needed). But pointers to
cleaner or easier existing ways to do this would be most appreciated.
In case it's of interest in the context of the question, I need to
define a largish set of functions (and similar methods) that define a
XML-type markup language. Most of these functions will just be of the form
def fun(...):
return Node('fun', ...)
so it'd definitely be nice to just create most of them automatically,
and only do the special cases by hand.
Many thanks,
Ken
