Installing the plugin

see http://www.xmlhack.com/read.php?item=2061

Download the plugin nxml-mode-20041004.tar.gz from:

Unpack it to ~./xemacs/nxml/

Edit ~./xemacs/init.el:

(setq load-path (cons (concat (aw-make-package-path "nxml") my-dir-sep) load-path))

;; XML
(load "rng-auto.el")

      (cons '("\\.\\(xml\\|xsl\\|rng\\|xhtml\\)\\'" . nxml-mode)
	    auto-mode-alist))
 

Realtime checks in Emacs

At first we need to convert the xml-schema file into a rnc file. For this download the program trang-20030619.zip from:
http://www.thaiopensource.com/download/

Execute it with:

java -jar trang.jar -I xml -O rnc ui.xsd test.rnc

Now you can load the file test.rnc with emacs from the menu XML->Set Schema->File...

UTF8

Check for Correct Coding

find /usr/local/share/munin/plugins/ -type f | while read f ; do echo "Checking $f" ; uniname -V $f ; done

Set Coding to UTF-8

C-x RET c utf-8 RET C-x C-s
