I think this kind of recursive grouping works best if you use a named template that is passed the contents of a group as a parameter. Try something like this: <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xsl:output indent="yes"/> <xsl:template name="group"> <xsl:param name="pop" as="element()*"/> <xsl:param name="level" as="xs:integer" /> <xsl:variable name="key" as="xs:string" select="concat('h', $level)"/> <xsl:for-each-group select="$pop" group-starting-with="*[name() eq $key]"> <xsl:choose> <xsl:when test="starts-with(name(.), 'h')"> <section level="{$level}"> <head><xsl:apply-templates select="current-group()[1]"/></head> <xsl:call-template name="group"> <xsl:with-param name="pop" select="remove(current-group(), 1)"/> <xsl:with-param name="level" select="$level + 1"/> </xsl:call-template> </section> </xsl:when> <xsl:otherwise> <xsl:copy-of select="current-group()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:template> <xsl:template match="/"> <doc> <xsl:call-template name="group"> <xsl:with-param name="pop" select="body/*"/> <xsl:with-param name="level" select="1"/> </xsl:call-template> </doc> </xsl:template> </xsl:stylesheet> | |
