You would have to use an extension function, but even then doing an
operation like POST from a side effect free language like XSLT is
slightly problematic. You have no assurances about the chronological
order in which any templates are evaluated, only that the results
of evaluating the templates are assembled into the final tree in the
correct place. So GET is relatively safe and made safer by the fact
that XSLT specifies that if you get the same URI twice in one transform
you must be returned the same representation (actually stronger the same
node-set)  but tying down the semantics of an update such as POST is
rather trickier.
