Thank you very much for both suggestions. So if I understand right I
either have to resort to something which looks to me like "recursion
into groups", applying xsl:for-each-group to the result of all previous
groupings, or I have to set up a kind of table of grouping keys on which
to branch.
A third approach came to my mind. When the order of elements in the flat sequence is fixed, the series of xsl:apply-templates instructions that process the remaining elements may be interrupted by the necessary xsl:for-each-group instructions, which then can immediately select the elements they have to group. Like this: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes"/> <xsl:template match="root">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template> <xsl:template match="flatsequence">
<hierarchy><xsl:apply-templates select="a"/> <xsl:for-each-group
select="b|c" group-adjacent="1">
<container1>
<xsl:copy-of select="current-group()"/>
</container1>
</xsl:for-each-group><xsl:apply-templates select="d|e|f"/> <xsl:for-each-group
select="g|h|i" group-adjacent="1">
<container2>
<xsl:copy-of select="current-group()"/>
</container2>
</xsl:for-each-group><xsl:apply-templates select="j"/> </hierarchy> </xsl:template> <xsl:template match="a|d|e|f|g|h|i|j">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template></xsl:stylesheet> That seems to work, but perhaps I am missing something? (If it's OK as it is: any idea how to specify the grouping criterion, which just has to evaluate as permanently true, more elegantly than using 'group-adjacent="1"'?) Yves
