Hi Pablo,
I don not know if this is what you are looking for, but I create a XoWiki page like this :
-------------------------------------------------
# Create PlainPage object
::xowiki::PlainPage create ::$page_name -noinit \
-set creator $creator_name \
-set object_type ::xowiki::PlainPage \
-set lang en \
-set text $body \
-set title "$title" \
-set nls_language en_US \
-name "en:$page_name"
# Import page object.
ns_log notice [::xowiki::Page import -objects ::$page_name -package_id $package_id -folder_id $folder_id]
--------------------------------------------------
