Spirit 2.1 does not have any special API functions for AST generation. It's
all intrinsic. You really should look at the examples (for instance
mini_xml[1-3].cpp) and read the docs (http://tinyurl.com/ojalum). The
introduction there guides you nicely through how it's done.

As for XML generation, we don't have this in Spirit 2.1 at all. Every parser
may now generate a structurally different PT/AST, so having a common dump
function is not feasible. You'll have to craft your own (the examples show
how you may want to do that as well).
