I realized this, and had changed to use `org-export-before-parsing-hook', here
is my code:

(defun my-headline-removal (backend)
  "Ignore headlines with tag `ignoreheading'."
  (save-excursion
    (when (eq org-export-current-backend 'latex)
      (org-map-entries (lambda ()
                         (when (member "ignoreheading"
(org-get-tags-at nil 'local))
                           (save-excursion
                             (org-map-tree 'org-promote))
                           (delete-region (line-beginning-position)
                                          (line-end-position))))))))

(add-hook 'org-export-before-parsing-hook 'my-headline-removal)

But I'm getting the error: "org-map-tree: Symbol's value as variable is void:
org-called-with-limited-levels". Any idea?

Thanks
