Yet another SEXP to HTML thing. This time with Plump back-end.
(plump:serialize (plump-sexp:parse '((div :id "foo") (p "bar") "baz")))
=> <div id="foo"><p>bar</p>baz</div>
Of course, you can now also transform any kind of Plump document into such an SEXP tree:
(plump-sexp:serialize (plump:parse "<div id="bar"><p>foo</p>baz</div>"))
=> (:!ROOT ((:DIV :ID "bar") (:P "foo") "baz"))
If you have tags with case differences, you can also use strings for the tag and attribute names.
