Good evening,
Emacs 24.4 and Org from Git.
Goal:
1) Visit every headline
2) If there is an ID property
1) Then replace it's value with a UUID
3) If there is not an ID property
1) Add an ID property and give it a UUID.
`org-uuid' [provides] the functionality to add the ID with a UUID.
[This post] explains how to do it:
┌────
│ (require 'org-id)
│ (save-excursion
│ (goto-char (point-max))
│ (while (outline-previous-heading)
│ (org-id-get-create)))
└────
What is the best way to do it with `org-element'?

Using `org-element' here would be sub-optimal. Headlines are context
insensitive, i.e., you don't need a parser to find one.
Anyway, the following should do:
(dolist (p (nreverse
(org-element-map (org-element-parse-buffer 'headline) 'headline
(lambda (headline) (org-element-property :begin headline)))))
(goto-char p)
(org-id-get-create))
Regards,

That works perfectly. Thank you.
Tempted to run it in a on-save hook just to ensure that the document
*always* has IDs. At least for tangle comments.

You might try setting `org-id-link-to-org-use-id' to either t or
'create-if-interactive. I believe I have it set to t, and I get ids
generated when I tangle.
HTH,
