I have customized indentation in nXML for XHTML documents. The exact
indentation rules I use are not relevant to your case but here’s how I
activate it.
See the documentation on ‘indent-line-function’ and the source of
‘nxml-indent-line’ for implementation details.
(defun yk-xhtml-indent-line ()
"Indent the current line suitably for XHTML."
<my custom indentation rules>)
(defun yk-xhtml-indent--maybe-enable ()
"Set the current buffer’s indentation function
to `yk-xhtml-indent-line' if the current schema is “html”."
(pcase (caddr rng-current-schema)
("html" (setq-local indent-line-function 'yk-xhtml-indent-line))))
(with-eval-after-load 'nxml-mode
(add-hook 'nxml-mode-hook 'yk-xhtml-indent--maybe-enable))
