This is very exciting. Let me ask two questions, however.
First, why not generate SAX events and then use your existing DOM builder
to make the formatting object tree. That way you would be able to daisy
chain XSL filters and other filters.
Second, is the API such that some of the facilities are useful from
Python? For instance can you easily look up nodes given a pattern, or do
an XSL pattern-based "visit" of a node tree?
I'm not sure if it is clear what I am getting at. XSL processing could be
regarded as a special case of "pattern-based tree visiting." That might
allow us to use an XSL visitor pattern in ordinary Python code.
