given

<root>
  <chapter><title>C1</title>
  <wrapper>
    <wrapper>
        <section><title>S1</title></section>
    </wrapper>
    <section><title>S2</title>
      <section><title>S3</title>
      </section>
    </section>
  </wrapper>
  </chapter>
</root>


(I moved /chapter to the end?)

and

<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


 <xsl:template match="chapter">

 <xsl:message select="
let $here:=. return
.//section[empty(ancestor::*[title] except
$here/ancestor-or-self::*[title])]/title
"/>

 </xsl:template>

</xsl:stylesheet>


the xpath in the message produces

<title>S1</title><title>S2</title>
