Martin,
Many thanks for your quick reply..
I ve found a part of the solution.
In fact, the part after http://mywebsite can be uk or sp and the lenght will 
be fixed (2 characters).

Is it possible to use Wildcard with the substring-after ?
Like
<xsl:key name="smain-by-type" match="smain" 
use="substring-before(substring-after(substring-after(lnk, 
'http://mywebsite/??/'), '/'), '/')"/>

By the way, how to display the two first elements of a group (if there are 
more than 2) and add dynamic link "Click here for more results".

I mean
Thriller
<ul>
    <li>Connelly</li>
    <li>Coben</li>
    <li>Click here for more results</li>
</ul>

And in final, it's out of topic. I need to replace the Group Name by another 
word.
I have another xml file that comes like this
<main>
        <title language="uk" word="thriller" commercial="American Thriller" 
/>
        <title language="sp" word="thriller" commercial="bla bla bla" />
</main>
So the goal is to get this

American Thriller
<ul>
    <li>Connelly</li>
    <li>Coben</li>
    <li>Click here for more results</li>
</ul>

Of course, it was very easier to do this job with asp but they ask me to do 
it with xslt..

I promise you, it should be the last question (I place an order for a book 
that I don't yet receive..).
