Hello,
I solved this with a backquote (instead of quote), I write this just in
case someone need an example (of what NOT to do :-D ).

OK the code above was included as part of <<sites_config>> in a list
like this:
--8<---------------cut here---------------start------------->8---
(setq org-publish-project-alist
'(
<<sites_config>>))
--8<---------------cut here---------------end--------------->8---
In this way all the sites_config part is _quoted_ (see the quote ad the
beginning of the org-publish-project-alist).
If I want the xmlgen code above to be evaluated, I have to backquote the
list and use the evaluator symbol (",") for the (xmlgen ...) block; this
way:
--8<---------------cut here---------------start------------->8---
(setq org-publish-project-alist
`(
[OMISSIS]
:html-preamble-format (("en"
,(xmlgen
'(div
(div
(a :href "/" "Home")
(span :class "pre-sep" "|")
(a :href "/colophon.html" "Colophon")))))
("it"
,(xmlgen
'(div
(div
(a :href "/" "Home")
(span :class "pre-sep" "|")
(a :href "/colophon.html" "Colophon"))))))))
--8<---------------cut here---------------end--------------->8---
...OK, lesson learned! :-D
Happy hacking!
Giovanni.
