Thanks a lot for the suggestion, it works. I did not use
`org-forward-element' as it does not iterate on sub-items. I simply do
a `forward-line' to go done.

Here is the code, if it's helpful to others.

    ; read the file in the temporary buffer
    ; do not add a \n at the end
    (condition-case nil
    (let ((line (read-from-minibuffer "")))

Thanks again,
