[xsl] Grouping by letters but keep symbols together

["Rick Quatro rick@xxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

 

I am creating a glossary and I want to group entries under each letter of
the alphabet. I am using this and it is working fine:

 

<xsl:for-each-group select="glossentry"
group-by="upper-case(substring(glossterm/text(),1,1))">

    <topicref navtitle="{current-grouping-key()}" toc="no">

...

    </topicref>

</xsl:for-each-group>

 

However, I want to group entries that start with a symbol or number all
together under one group. I am not sure what to use for the group-by
attribute so that letters are separate from each other and all of the
non-letter characters are in the same group. Any suggestions would be
appreciated. Thank you very much.

 

Rick
