I have done a lot of text file generation in Jython and Java using
dom4j as the data model and Velocity as the template engine. It's a
very powerful combination.
dom4j elements have XPath accessors so you can say for example
myElement.selectNodes('some/xpath'). Velocity supports introspection on
its data so in a template I can say
#foreach $item ($parent.selectNodes("some/xpath"))
(my syntax may be a little off, this is from memory)
ISTM you should be able to do the same thing from CPython with a dom
model that has XPath accessors and a template engine that supports
calling methods on its data. I think lxml and Cheetah, among others,
would work this way.
