Sorry,  the output would realy end up looking something like:
<div class="bar">
<span class="ant">
<a href="incipits/ant/T.html"><img src="images/goto.png" alt="Go"/></a>
<span class="rubglyph">A.</span> This is a test. </span>
</div>

from something like:
><bar type="ant"><rub type="glyph">A.</rub> This is a test.</bar>

It is the formation of the filename part of the URL.  I can do all the
other parts, it was just getting the first-letter that was puzzling me.
As it is to provide a clickable image leading to the page of
incipits starting with this letter.  I've used translate() to
make sure the (usually upper case) letters are upper since they
will always be a-z.

Yup, and a quick test seems to indicate that works!  I'm not
entirely sure I understand text()[normalize-space()] though.
That selects the text() node restricting it to the normalize-spaced
version of itself?

David to the rescue as usual!

Many thanks,
James
