Here's a stylesheet which solves this problem:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="html">
<book>
<chapter>
<xsl:apply-templates select="body/h1[1]/preceding-sibling::p" />
<xsl:for-each-group select="body/*" group-starting-with="h1">
<xsl:if test="position() > 1">
<section>
<xsl:apply-templates select="current-group()"/>
</section>
</xsl:if>
</xsl:for-each-group>
</chapter>
</book>
</xsl:template>
<xsl:template match="h1">
<title>
<xsl:apply-templates />
</title>
</xsl:template>
<xsl:template match="p">
<para>
<xsl:copy-of select="node()" />
</para>
</xsl:template>
</xsl:stylesheet>
For the output you're seeking, you need to discard the 1st group. The
explanation of group formation, with 'group-starting-with' can be
found at:

Hi. I'm new to XSLT and I'm trying to write a 2.0 stylesheet to wrap
HTML elements in DocBook <section> elements. I'm finding that
<xsl:for-each-group> wraps elements in a <section> even when they are
not preceded by the element I name in the group-starting-with
attribute.
For example, I'm converting the HTML <body> element to a DocBook
<chapter> element. If the HTML includes <p> elements before the first
<h1> element, they should become <para> elements that are children of
the <chapter> element. I name <h1> in the group-starting-with
attribute but my output includes a <section> element around the first
<para> elements.
My processor is Saxon HE 9.2.1.1. I've pasted the source, stylesheet,
and output below. Am I using the for-each-group element incorrectly? I
figured out a way to work around this problem by including a predicate
[preceding-sibling::h1] in the select attribute for it. However, this
won't work when I need to wrap <h2> and <h3> sections later in the
document.
Has anyone dealt with this situation before? Thanks for your help.
Peter
