Hi Michael,
Thank your for your response. I tried to adapt your solution but I don't get it well. Maybe I didn't understand your algo but this is what I come out : I supposed nodes param should be node()* typed and the for-each loop should be applied to $nodes, is this correct? But then I don't understand why using a group-starting-with, then all my level should be one inside the other, which is not really what I want. My goal is to prevent *orphans* title, that's why I need to group each title with his first-sibling (with conditions as said before). I do that to simulate the css rule page-break-after:avoid wich doesn't work well with electronic books. Anyway this is the XSLT : <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/1999/xhtml" xpath-default-namespace="http://www.w3.org/1999/xhtml" > <xsl:output method="xml" indent="yes"/> <!--default copy--> <xsl:template match="* | @* | processing-instruction() | comment()"> <xsl:copy copy-namespaces="no"> <xsl:apply-templates select="node()|@*"/> </xsl:copy> </xsl:template> <!--keep namespace on top element--> <xsl:template match="html"> <html xmlns="http://www.w3.org/1999/xhtml"> <xsl:apply-templates/> </html> </xsl:template> <xsl:template match="body"> <xsl:copy copy-namespaces="no"> <xsl:copy-of select="@*"/> <xsl:call-template name="group"> <xsl:with-param name="level" select="1"/> <xsl:with-param name="nodes" select="*"/> </xsl:call-template> </xsl:copy> </xsl:template> <xsl:template name="group"> <xsl:param name="nodes" as="node()*"/> <xsl:param name="level" as="xs:integer"/> <xsl:variable name="hN" select="concat('h', $level)"/> <xsl:for-each-group select="$nodes" group-starting-with="*[local-name() = $hN]"> <xsl:choose> <xsl:when test="local-name(current-group()[1]) = $hN"> <div class="group"> <xsl:apply-templates select="current-group()[1]"/> <xsl:call-template name="group"> <xsl:with-param name="nodes" select="current-group() except current-group()[1]"/> <xsl:with-param name="level" select="$level + 1"/> </xsl:call-template> </div> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="current-group()[1]"/> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:template> </xsl:stylesheet> I will trie to add a "group-ending-with" inside the group-starting-with...
