I would like to specify the TeX engine with the emacs command line, such
as with C-c C-c latex and C-c C-c xelatex, rather than having it only
call whichever TeX-engine is specified in AUCTeX configuration or in
.emacs init file. At present I can only switch between processing LaTeX
and XeLaTeX files by inserting or commenting a line in .emacs (setq
TeX-engine 'xetex) and reload emacs.
Simplest would be to have AUCTeX not specify any TeX-engine and instead
use the engine specified at the command prompt. There does not seem to
be any way to do this, and so an alternative might be for .emacs to
specify the TeX engine by distinguishing between LaTeX and XeLaTeX
files.
Someone using the Jed editor does this. He sets the default TeX-engine to
xetex if the document uses packages peculiar to XeTeX:
if (re_fsearch("\\usepackage.*unicode-math") or
re_fsearch("\\usepackage.*fontspec") or
re_fsearch("\\usepackage.*polyglossia")
)
define_blocal_var("latex_output", "xetex");
Is it possible to something comparable to this if construction in .emacs
init? I know nothing of lisp, but guess it would be something like:
( if
(search-forward "\usepackage*fontspec") or
(search-forward "\usepackage*polyglossia")
(setq TeX-engine 'xetex))

If you know nothing of Lisp this may not help you but I'll paste my
settings anyway. It could be modified to match your needs.
(add-hook 'LaTeX-mode-hook #'tl-latex-mode-hook)
(defun tl-latex-mode-hook ()
(add-to-list 'TeX-command-list
'("XeLaTeX" "%`xelatex%(mode)%' %t" TeX-run-TeX nil t))
(setq TeX-command-default
(save-excursion
(save-restriction
(widen)
(goto-char (point-min))
(let ((re (concat "^\\s-*\\\\usepackage\\(?:\\[.*\\]\\)?"
"{.*\\<\\(?:font\\|math\\)spec\\>.*}")))
(save-match-data
(if (re-search-forward re 3000 t)
"XeLaTeX"
"LaTeX"))))))
(auto-fill-mode 1)
(outline-minor-mode 1)
(abbrev-mode 1)
(setq fill-column 72))

You can do it by creating a custom command, by adding entries to
TeX-command-list. Then you can change the command to call when
using C-c C-c.

If I understand, this presumes that initially latex is the default
TeX-engine, but it adds the xelatex engine to the available commands
if the expression is matched. This expression is way beyond my ken.
Would it be possible instead to put a comment line just before the
preamble of a document that contains either the word "latex" or
"xelatex" (assuming those words do not appear elsewhere in the
document) and base the forward search on it? Also, for my purposes it
would probably be more convenient to make xelatex the default
TeX-engine and if the word "latex" is found it would instead be used
as the TeX-engine. I assume this would also avoid having to enlarge
the TeX-command-list because I suppose latex would already be in it.

Thank you for the lisp suggestion. Subsequently I stumbled on a very
simple answer to my question of running either the latex or xelatex
commands without reconfiguring and restarting emacs: simply add
xelated to the AUCTeX configuration for TeX-engine. I added xelatex
and it can now be called for xelatex files and the latex command is
still accessible for latex files. At least this seems to work so far.

You can set the engine as a file variable in the files which require
XeTeX.
For example like this:
%%% Local Variables:
%%% mode: latex
%%% TeX-engine: xetex
%%% TeX-PDF-mode: t
%%% TeX-master: t
%%% End:

AUCTeX uses style files for things like this. For example for
fontspec.sty you'd write a file called fontspec.el which is placed in
AUCTeX's style directory and which switches the TeX engine to XeTeX.
See (info "(auctex)Style Files") for details.
