fontifying emacs w3m view source buffer

[Peter K . Lee]

I'm doing some server-side web stuff, and was using emacs-w3m mode to
verify generated HTML text.

I wanted to know if there were existing hooks or calls from other
emacs packages to fontify the w3m view source buffer (since it's just
HTML after all).

Since I was using NXML for authoring, I tried adding something like
the following...

(defun saint/w3m-nxml-view (url)
  "Suitable for adding to `w3m-display-hook'."
  (if (string-match "\\`about://source/" url)
          (progn
                (require 'nxml-mode)
        (nxml-mode))))
(add-hook 'w3m-display-hook 'saint/w3m-nxml-view)

which does work in fontifying buffer, but you're thrown out of w3m
mode completely.

(defun saint/w3m-nxml-view (url)
  "Suitable for adding to `w3m-display-hook'."
  (if (string-match "\\`about://source/" url)
          (progn
                (require 'nxml-mode)
        (nxml-fontify-buffer))))
(add-hook 'w3m-display-hook 'saint/w3m-nxml-view)

I then tried the above, but call to nxml-fontify-buffer does not seem
to work.

Any suggestions?

TIA,

Peter
