I am probably off-target on this issues, but theoretically it
should be possible, at least to a certain degree. I am not
proposing that this should be part of libxml, but rather that
it could be built on top of libxml.
I recently had a discussion about how to use the SAX interface
to build a parse tree that only contains the parts of an XML
document that satisfies a set of XPath expressions. This can,
theorically, be done by using state machines (something similar
is done in Constraint Based Programming).
I have not given this detail thought, but I believe that this
could also be used to create a callback based system for XPath
expressions.
Disclaimer: I do not claim that this is an easy task.
