 Thanks Michael. (As Abel pointed out, I'm replying to the digest since that's what I receive). This works nicely. I don't understand the difference between <xsl:apply-templates select="."/> and <xsl:apply-templates select="current-group()"/> within the xsl:for-each-group instruction. The book says ' use current-group() is sometimes better especially if the group includes elements of different types' which this example does. How can I understand the difference please?

Message-ID: <009e01c7769e$d165d290$6401a8c0@turtle> I think your problem is that <xsl:apply-templates select="current-group()"/> is processing all the elements in a group, not only the next-level headings - so the paragraphs are output at every level. 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> ___________________________________________________________ New Yahoo!
