Are you just trying to implement an ignoreheading filter?
This is what I use. I think Nicolas provided it in a post at some
point but I'm not sure.
(defun rasmus/org-latex-ignore-heading (headline backend info)
"Strip headline from HEADLINE if it has tag ignoreheading for
certain headlines. `info' is Ignored"
(when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
(string-match "\\`.*ignoreheading.*\n"
(downcase headline)))
(replace-match "" nil nil headline)))
(add-to-list 'org-export-filter-headline-functions
'rasmus/org-latex-ignore-heading)
