You have to use a bit of a trick to get this to work. You want to get
the //user/nokeyuser/name element(s) if $anznokeyuser is more than
$anzkeyuser, and //user/keyuser/name otherwise. The best way to do
this is to create a union of the //user/nokeyuser/name (if
$anznokeyuser > $anzkeyuser):

  (//user/nokeyuser/name)[$anznokeyuser > $anzkeyuser]

and //user/nokeyuser/name (if $anznokeyuser <= $anzkeyuser):

  (//user/keyuser/name)[not($anznokeyuser > $anzkeyuser)]

So use:

  <xsl:variable name="anzrows"
    select="(//user/nokeyuser/name)[$anznokeyuser > $anzkeyuser] |
            (//user/keyuser/name)[not($anznokeyuser > $anzkeyuser)]"/>
  <xsl:for-each select="$anzrows">
    ...
  </xsl:for-each>
            
Cheers,

Jeni
