Re: Sorting + unique copy problem

Ah, yes, of course...

Well, here's my solution - it works with your scrambled keywords too.  I
like to turn unique list into a variable by itself. That way I can use it
for other things with it later on:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method='html'/>

<xsl:key name="kw" match="KeyWord" use="."/>
<xsl:variable name='keywords'
    select='/Filmlist/Film/KeyWord
       [generate-id(.)=generate-id(key("kw",.)[1])]'/>

<xsl:template match="/">
    <form action="process_user.jsp" TARGET="result" method="get">
       <select type="text" name="kw" size="20" maxlength="125">
          <option value="empty"/>
          <xsl:for-each select="$keywords">
              <xsl:sort select='.'/>
           <option value="{.}"><xsl:value-of select="."/></option>
       </xsl:for-each>
        </select>
    </form>
</xsl:template>

</xsl:stylesheet>


BTW, I just ordered your book ... hoping for great things from it!

Cheers,

Tom
