Hello, I'm a newbie with Elisp and Lisp in general; what I'm trying to do is to customize the preamble format for a publishing-project I'm using. I'm able to configure the HTML preamble for each project using this configuration; --8<---------------cut here---------------start------------->8--- ("Pagine in italiano" :language it [...] :html-preamble t :html-preamble-format (("en" "
") ("it" ""))) --8<---------------cut here---------------end--------------->8--- This works well but I'd like to use xmlgen to format the html parts of :html-preamble-format If I use this: --8<---------------cut here---------------start------------->8--- :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--- (yes I know, the HTML results of xmgen does not match with the ones above but that's not the issue) I get this error: Wrong type argument: char-or-string-p, (xmlgen '(div (div (a :href "/" "Home") (span :class "pre-sep" "|") (a :href "/colophon.html" "Colophon")))) If I try to evaluate the (xmlgen ...) part in a separate buffer I get correct sting representation in HTML but in ":html-preamble-format" it does not work. Please what I'm doing wrong? Thanks! Giovanni. -- Giovanni Biscuolo
