I hope your elements are *not* named item1, item2, item3...
But if you really want:
 <xsl:for-each select="*[substring(name(),1,4)='item']">
   <class>
     <xsl:choose>
       <xsl:when test="position() mod 2 = 0">
          <xsl:attribute name="name">even</xsl:attribute>
       </xsl:when>
       <xsl:otherwise>
          <xsl:attribute name="name">odd</xsl:attribute>
       </xsl:otherwise>
     </xsl:choose>
     <xsl:apply-templates/>
   </class>
 </xsl:for-each>
(Beware: untested)

I'm not sure what the "twist" is, it's a standard technique.
