Hi there,
as we all know, everything is better with XML, so here's a puzzle for
all interested (I call it a puzzle and not a bug because I finally
solved it).
Download the xmlgen library (https://github.com/philjackson/xmlgen) and
execute this code:
(require 'xmlgen)
(with-temp-file "foo.xml"
(insert (xmlgen '(hello (world (of (xml) "!")))))).
Visit file foo.xml, do this:
C-x h M-x sgml-pretty-print
and enjoy your beautifully formatted (and indented!) XML code.
Now rinse and repeat, but with one change:
(require 'xmlgen)
(with-temp-file "foo.xml"
(insert (xmlgen '(hello (world (of (xml) "!")))))
(sgml-pretty-print (point-min) (point-max)))
and answer this question: where have all the indents go?
;-D
Best,

Ok let's play the game (i.e. I didn't try) : My guess is that since
`with-temp-file' doesn't set the major mode (i.e. it will be
fundamental-mode), there are local variables which are not set as
sgml-pretty-print would expect.

Good catch! To be more precise: sgml-pretty-print calls
reindent-then-newline-and-indent, which depends on the mode.
It took me almost half an hour of frustration... I guess this is just
another step on the path to real Emacs expertise, which I hope to finish
within a two-digit number of years... (That assuming that "finishing"
it is at all possible.)
Best,
