Re: *****SPAM***** [xsl] Using for-each-group on a <day> collection to arrange a weekday calendar

["Christophe Marchand cmarchand@xxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Replacing your for-each-group by this works correctly for me :

 B B B B B B B B B B B B B  <xsl:variable name="days" as="element(day)+" 
select="descendant::day"/>
 B B B B B B B B B B B B B  <xsl:for-each-group select="$days" 
group-ending-with="day[((count(preceding::day)+1) mod 5) eq 0]">

All the other code has not been changed. Well, a little bit, to display 
Day x... because I have no title in my data.

Best regards,
Christophe
