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

Hi Michael and Martin,
I believe you are right, no general solution exists for the reasons Michael 
mentioned.
However, for the archives, I ended up with this monstrosity that does the 
job (ugly as it is):
<xsl:for-each-group select="Word" group-by="if 
(lower-case(substring(@word,1,1)) eq 'č' or lower-case(substring(@word,1,1)) 
eq 'ř' or lower-case(substring(@word,1,1)) eq 'š' or 
lower-case(substring(@word,1,1)) eq 'ž') then 
lower-case(substring(@word,1,1)) else if (lower-case(substring(@word,1,2)) 
eq 'ch') then 'ch' else lower-case(substring(cps:remove-diacritics(@word), 
1, 1))">
     <xsl:result-document href="{concat('index/cz-', 
current-grouping-key())}.htm">
Where cps:remove-diacritics() is defined as:
<xsl:function name="cps:remove-diacritics">
   <xsl:param name="in-string"/>
   <xsl:value-of select="replace(normalize-unicode($in-string, 'NFKD'), 
'[&#x0300;-&#x036F;]', '')"/>
 </xsl:function>

Thanks all,
Mark
