Can emacs re-indent a big blob of HTML for me?

Answer 1

i wrote a function myself to do this for xml, which works well in nxml-mode. should work pretty well for html as well:

(defun jta-reformat-xml ()
  "Reformats xml to make it readable (respects current selection)."
  (interactive)
  (save-excursion
    (let ((beg (point-min))
          (end (point-max)))
      (if (and mark-active transient-mark-mode)
          (progn
            (setq beg (min (point) (mark)))
            (setq end (max (point) (mark))))
        (widen))
      (setq end (copy-marker end t))
      (goto-char beg)
      (while (re-search-forward ">\\s-*<" end t)
        (replace-match ">\n<" t t))
      (goto-char beg)
      (indent-region beg end nil))))
