How about something like:

(element (title)
  (let* ((title-kids (children (current-node)))
           (title-str (data (node-list-filter title-kids
                                                        (lambda (node)
                                                           (equal?
(node-property 'class-name node)

'data-char)))))
  )
    (make paragraph
      (process-children))))

title-str will be bound to a string that contains just the data characters that
are children of the <title> element. You'll need to define node-list-filter
which can be found in the DSSSL standard.
