Try something like

(default (process-node-list (element-children)))

(element one-I-want
  (do-something))

where (element-children) is defined as:

;; (element-children snl) finds all of the elements that are direct
;; children of singleton nodelist "snl".  This is useful for
;; filtering, processing, and counting, when you're not interested in
;; any text, PI, or comment nodes.
(define (element-children #!optional (snl (current-node)))
  (select-by-class (children snl)
                   'element))
