My XSLT:
<xsl:stylesheet version="2.0"

<xsl:output method="xml" indent="no" encoding="iso-8859-1"

	<xsl:template match="html">

		</chapter>
	</xsl:template>

	<xsl:template match="*">
		<xsl:copy>
			<xsl:copy-of select="@*"/>
			<xsl:apply-templates/>
		</xsl:copy>
	</xsl:template>
	<xsl:template match="body">
	<body>
		<xsl:for-each-group select="*"
group-adjacent="string(self::p/@class)">
			<xsl:choose>
				<xsl:when
