Here is my xsl code
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*" mode="pretrans">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="p[count(child::node())=0]" mode="pretrans"/>
<xsl:template match="doc">
<poc>
<xsl:apply-templates/>
</poc>
</xsl:template>
<xsl:template match="text">
<chapter>
<xsl:variable name="pos" select="count(child::node()[#style='H5']/preceding-sibling::p)+1"/>
<xsl:apply-templates select="child::node()[position()<$pos]" mode="presec"/>
<section>
<xsl:variable name="nodesets" >
<xsl:apply-templates select="child::node()[position()>=$pos]" mode="pretrans"/>
</xsl:variable>
<xsl:apply-templates select="$nodesets" mode="postsec"/> <!---->
</section>
</chapter>
</xsl:template>
<xsl:template match="p" mode="presec">
<xsl:choose>
<xsl:when test="#style='H2'">
<title><xsl:apply-templates/></title>
</xsl:when>
<xsl:when test="#style='H4'">
<subdivision>
<title><xsl:apply-templates/></title>
</subdivision>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="p" mode="postsec">
<xsl:variable name="pos" select="count(preceding-sibling::p[#style='H5'][1]/preceding-sibling::p)+1"/>
<xsl:variable name="pos" select="count(preceding-sibling::p)+1"/>
<xsl:variable name="styleblock" select="count(preceding-sibling::p[#style='BlockStyle'][1]/preceding-sibling::p)+1"/>
<xsl:choose>
<xsl:when test="#style='H5'">
<title><xsl:apply-templates/></title>
</xsl:when>
<xsl:when test="count(child::node())=0"/>
<xsl:otherwise>
<paragraph>
<xsl:if test="#style='BlockStyle'">
<quotes>
<xsl:apply-templates/>
</quotes>
</xsl:if>
<xsl:apply-templates/>
</paragraph>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>

Depending on your needs delete the first or the second
<paragraph>
<xsl:if test="#style='BlockStyle'">
<quotes>
<xsl:apply-templates/><!-- First -->
</quotes>
</xsl:if>
<xsl:apply-templates/><!-- Second -->
</paragraph>
