This is nonsense. XPath and friends are not bound to the external
representation of the data in any way. They operate on the DOM tree. So
as long as your XML conversion to sexp format is lossless (which it
should be, of course), you lose nothing, only gain the advantages of
saner format (i.e. sexp) both for humans and the machine -- you just
need an XPath etc. implementation for your language.
