Here is an XSLT stylesheet that produces the described result:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="1.0">

   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="datasets">
     <xsl:copy>
       <dataset set="result">
         <xsl:copy-of select="dataset[@set = '1']/data[not(. = 
/datasets/dataset[@set = '2']/data)]"/>
       </dataset>
     </xsl:copy>
   </xsl:template>

</xsl:stylesheet>
