Here is an attempt with a function:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:xsd="http://www.w3.org/2001/XMLSchema";
  exclude-result-prefixes="xsd mf"
  xmlns:mf="http://example.com/2009/mf";
  version="2.0">

  <xsl:output indent="yes"/>

  <xsl:function name="mf:group-heading" as="element()*">
    <xsl:param name="els" as="element()*"/>
    <xsl:param name="level" as="xsd:integer"/>
    <xsl:for-each-group select="$els" 
group-starting-with="*[local-name() eq concat('h', $level)]">
      <xsl:element name="{local-name()}">
        <xsl:apply-templates/>
        <xsl:sequence select="mf:group-heading(current-group() except 
., $level + 1)"/>
      </xsl:element>
    </xsl:for-each-group>
  </xsl:function>

  <xsl:template match="root">
    <xsl:copy>
      <xsl:sequence select="mf:group-heading(*, 2)"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

When applied to

<root>
<h2>testing</h2>
<p>data recovery, and application testing. </p>
<h4>Support for file system</h4>
<p>Objects for replication:</p>
<h3>Session</h3>
<p>Before creating sessions... </p>
<h3>Wizard</h3>
<p>In Manager, you can . </p>
<h4>Support for file system</h4>
<p>Objects for replication:</p>
<h2>testing1</h2>
</root>

Saxon 9 gives me

<root>
   <h2>testing<p>data recovery, and application testing. <h4>Support 
for file system<p>Objects for replication:</p>
         </h4>
      </p>
      <h3>Session<p>Before creating sessions... </p>
      </h3>
      <h3>Wizard<p>In Manager, you can . </p>
         <h4>Support for file system<p>Objects for replication:</p>
         </h4>
      </h3>
   </h2>
   <h2>testing1</h2>
</root>

which I think has the structure you want, you might need to tune the 
whitespace/indentation.
