Would something like this fit in xml.el: (defun freemind-get-child (parent path) (message "freemind-get-child %s %s" parent path) (let* ((childs (cddr parent)) (step (car path)) (step-node (if (listp step) (car step) step)) (step-num (if (listp step) (cdr step) 1)) (path-tail (cdr path)) (path-child (catch 'path-child (dolist (child childs) (when (and (not (stringp child)) (eq step-node (car child))) (when (= 1 step-num) (throw 'path-child child)) (setq step-num (1- step-num))))))) (if path-tail (freemind-get-child path-child path-tail) path-child)))
