Re: [xsl] Can group-by treat its target it two ways?

["Mark" <mark@xxxxxxxxxxxx>]

Hi Martin,
Although the expressions looks as though it should work, it does not produce 
the 'ch' file and does produce a lot of accented letter files that should 
have been combined. My peculiar:
<xsl:for-each-group select="Word" group-by="if 
(lower-case(substring(@word,1,2)) eq 'ch') then 'ch' else 
lower-case(substring(@word,1,1))">
actually does work.

Your suggestion would have been far simpler, though.
Thanks,
Mark

What happens with
  <xsl:for-each-group
    select="Word"
    group-by="lower-case(substring(@word,1,1))"
    collation="http://saxon.sf.net/collation?lang=cs";>
?
