I have not looked yet at libxml XPath support, anyway a question ..

In my understanding XPath is some kind of navigation language for XML
trees, I hope this is right ...

So, in libxml, is the XPath support tied to the libxml document
structures or does it use callbacks, so that one can hook in any
structure ? Eg if I would have navigation like that:

  "up().up().left()" (don't know correct XPath yet ..)

it would be nice if this would turn into SAX like callback invocations,
eg

  void *navctx;

  navctx = _xpath_up(parser, navctx)
  navctx = _xpath_up(parser, navctx)
  navctx = _xpath_prevSibling(parser, navctx)

?

Any suggestions, opinions ?
