Did you try
xsl:for-each select="LogEvent[*[name()=$selColumn]=$filter]">

If you need different numbers of terms e.g.

 <xsl:variable name="filterExpr">
   <xsl:for-each $params>
     <xsl:call-template name="build-term">
   </xsl:for-each>
  </xsl:variable>
 
have a look at the saxon:evaluate function.

Hope it helps, Edwin
