All strings contained in an element or a secondary string have a parent
property.  Try 

  (org-element-map (org-element-parse-buffer) 'plain-text 'identity)

on the following Org buffer

  #+begin_src org
  * A
  B
  #+end_src

No. The secondary values are lists: "topic number one", which has
a :parent property, belongs to a list stored in :title property.  That
list is the secondary value.

Why would they be changed? The :parent reference in the headline is
another headline, or the full tree whereas the :parent reference in
these strings is the headline itself. IOW, they are unrelated.

As said in my previous post, `org-element-map' can access them.

Do you have a simple example showing what you want to achieve?
