You should mention what DTD you're using.

I have done the following for a little custom XML DTD we use.  You're
going to have to extrapolate this for your data.  Especially see the
'select-elements' procedure, which you need to tune to just select the
proper tables (with the attribute setting you're looking for), and
then take that node list and squeeze it thru you LOT formatter
($participant-list$ in this example).

(mode participant-list-mode
  (element project.participant
    (let ((role (attribute-string (normalize "role"))))
      (make element gi: "LI"
	    (make element gi: "A"
		  attributes: (list
			       (list "NAME" (attribute-string
					     (normalize "id"))))
		  (process-children))
	    (if (string? role)
		(make sequence
		  (literal ", ")
		  (make element gi: "EM"
			(literal role)))
		(empty-sosofo))))))

(define ($participant-list$ nl)
  (make element gi: "UL"
	(with-mode participant-list-mode
	  (process-node-list nl))))

(element project.info
  (let* (personnel (select-elements (children (current-node))
				       (normalize
					"project.participant")))
	(has-personnel (not (node-list-empty? personnel))))
    (make sequence
      (make element gi: "H3"
	    (literal "Personnel:"))
      (make element gi: "P"
	    (if has-personnel
		($participant-list$ personnel)
		(empty-sosofo))))))
