There seems to be no need to use nodeset function. You
can simply write the XSL as below -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  
<xsl:output method="html" indent="yes" />
  
<xsl:template match="/root">  
  <xsl:apply-templates select="currentnode" />
</xsl:template>
  
<xsl:template match="currentnode">
  <p><xsl:value-of
select="sum(preceding-sibling::sibling/@value)" /></p>
</xsl:template>
  
</xsl:stylesheet>

When the above XSL is applied to XML -
<?xml version="1.0" encoding="UTF-8"?>
<root>
 <sibling value="5"/>
 <sibling value="7"/>
 <sibling value="9"/>
 <sibling value="13"/>
 <currentnode>some text</currentnode>
</root>

the o/p recieved is -
<p>34</p>
