>    Below is a XSLT 2.0 solution:

That's a possible solution, but I would do it in push style:

     <xsl:stylesheet version="1.0"
       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns:xs="http://www.w3.org/2001/XMLSchema">
   
     <xsl:output indent="yes" />

     <xsl:template match="/">
       <xsl:for-each select="data/row">
         INSERT INTO DBO.TEST
              (COL1, COL2, COL3, COL4) VALUES(
              <xsl:value-of separator=",">
                <xsl:apply-templates/>
              </xsl:value-of>
          );
       </xsl:for-each>
     </xsl:template>

     <xsl:template match="row/*">
       <xsl:sequence select="concat($apos, normalize-space(.), $apos)"/>
     </xsl:template>

     <xsl:template match="row/*[normalize-space(.) = '']">       
       <xsl:sequence select="'NULL'"/>
     </xsl:template>

    <xsl:variable name="apos" as="xs:string">'</xsl:variable>
  
    </xsl:stylesheet>
