Re: the last substring

I have an element like:
<elem>xxxxx.xxxxx.xxxx.1234</elem>

I know substring-before() will read the value before
the first '.'.

I wonder how I can read the value after the last '.',
namely 1234.

Last week I added a new template to the XSLT Standard Library
for retrieving the substring after the last occurrance of
a given substring.

You can either get the latest stylesheets from CVS, wait until the
next release or send me an email for the latest snapshot.

Cheers,
Steve Ball
