This is another good one. Keep it up! I have a simple question. How can I eliminate duplicates after sorting? The following : -- boy -- boy -- girl -- man -- man -- woman should become -- boy -- girl -- man -- woman after eliminating duplicates. Any suggestion? Thanks (ca).

  You can use something like this:
  --
  <xsl:for-each select="//Nodes/Type[not(.=preceding::Type)]">
  <xsl:sort select="Type"/>
  <xsl:variable name="actualType" select="."/>
  <Type>
  <xsl:value-of select="."/>
  </Type>
  <Amount>
  <xsl:value-of select="count(//Nodes/Type[.=$actualType])"/>
  </Amount>
  </xsl:for-each>
  --
  The structure should look like this:
  <Nodes>
  <Type>Boy</Type>
  <Type>Girl</Type>
  <Type>Boy</Type>
  <Type>...</Type>
  </Nodes>

  
  You should see if preceding is useful for your xsl xsl processor.
  Hope it can help you
