XML style selected by browser language setting?

This is what I am trying to achieve without much success so far:

On a local harddrive or network (so there is no web server involved) the
user will point his file browser at some xml file. The xml file will
reference an xsl stylesheet like this:

<?xml-stylesheet type="text/xsl" href="Stylesheet.xsl"?>

My aim is for the stylesheet to find out the language setting of the user's
browser. I have tried JavaScript navigator.language. While I managed to show
the language setting in the browser window, what I really want, is to select
language dependent style info, like keywords, data format, etc., based on
the language setting. So, if my xml file contains something like this:

<Distance>100</Distance>

With a browser language setting of German this might automatically be
displayed as:

Entfernung: 100 km

and with English-US as:

Distance: 62 miles

My problem is not having multiple stylesheets achieving this, or using
external files with the language dependent info, the problem is the
automatic selection of the proper styling based on the browser setting.

I do not want to have the user having to select a language by some on-screen
mechanism. This only has to work in Internet Explorer 6.0, but if this also
works for other browsers that would be even better.

Since I am relatively new to the combination of xsl and scripting I would
appreciate an answer with foolproof examples that I can understand.

Cheers

Harald
