Re: [xsl] Nested for-each-group and current-group()

Rick,
Think on second group you want B <xsl:for-each-group
select="current-group()/*">
Try this:

This does something slightly different in the presence of commentsB  and
processing instructions i think. THe coffee hasn't worked here yet.

Also, Rick already has <xsl:apply-templates select="current-group()">
elsewhere in their XSLT :)
