MSXML supports an extension function to convert a result tree fragment 
into a node-set, the function is named node-set and is in the namespace 
urn:schemas-microsoft-com:xslt so you can do e.g.
  <xsl:variable name="v1"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" 
select="msxsl:node-set($confirm_active_program)"/>
  <xsl:when test="not($v1/program[@active =
'true'])">
