Even before I had decided to use Emacs as my default editor I had read about nXML mode, an add-on for GNU Emacs which turns it into a powerful XML editor with continuous validation and completion. Since I use XML files to store allmost all the content on this web site - using a Perl program to generate the actual HTML files - I decided to give this mode a try, instead of using Exchanger XML Lite on Ubuntu. The latter had been my XML editor of choice for quite some time on Windows XP Professional. But I missed several features, like for example spell checking and macro recording.
First I downloaded the latest version of nXML mode, dated the 4th of October, 2004 via a link on the nXML mode web page.
Next, I decompressed and unpacked the downloaded file using:
tar zxvf nxml-mode-20041004.tar.gz
Then I moved the newly created directory,
.emacs.d directory located in my home directory:
mv nxml-mode-20041004 ~/.emacs.d
If you have more than one user on your system interested in using nXML mode, you might want to install the nXML directory in a more suitable location, but for me this would do for now.
Next, using Emacs I created the init.el file, which wasn't in my
C-x C-f ~/.emacs.d/init.el
and entered the following lines:
(cons '("\\.\\(xml\\|xsl\\|rng\\|xhtml\\)\\'" . nxml-mode)
The first line loads the nXML mode into Emacs. If you have moved the nXML mode directory to a different location, or downloaded a different version, make sure to modify the path.
The second piece of Emacs Lisp turns on
nxml-mode for several file extensions.
