Hi Ahmad,

I finally seem to understand the problem.

To solve it, please, replace the end of the stylesheet with the following:

    <xsl:for-each select="$vUniqueCharactersSending">
      <xsl:value-of select="concat('Character_ID: ',
                                   CHARACTER_ID,
                                   ':',
                                   $NL
                                   )"/>
      <xsl:for-each 
          select="/LOG/DIRECT/CHARACTER_ID
                                [. = current()/CHARACTER_ID]">


        <xsl:if test="not(../LOCATION_ID 
                          = ../preceding-sibling::DIRECT
                                [CHARACTER_ID = current()]/LOCATION_ID)">
                                
          <xsl:value-of select="concat('    ', ../LOCATION_ID, $NL)"/>
        </xsl:if>

      </xsl:for-each>

    </xsl:for-each>

  </xsl:template>
</xsl:stylesheet>


Now the transformation does not produce duplicate rooms for a character.

Cheers,
Dimitre.
