Re: [xsl] How to sort a $variable and store that into another $variable ?

["Jean-Philippe Martin" <jeanph01@xxxxxxxxx>]

Ok.
I'll try to make this understandable.

My need is :
- extract a list of values
- make it unique
- make it sorted
- put it on many columns in a html table

My XML document is big. I create an unordered list of unique values
with this call  (the first // is important since the info can be
anywhere in the xml tree) :

<xsl:variable name="unsortedList"
select="//category[@defid=3183315]//*[@attid=49]/node()[not(.=following::*)]"
/>


I put this list in a variable because i want to make a multi-column
html table with the values. And the technique I used needs a variable

  <table style="width:100%; ">
    <xsl:variable name="unsortedList"
select="//category[@defid=3183315]//*[@attid=49]/node()[not(.=following::*)]"
/>
    <xsl:variable name="nbCol" select="ceiling(count($unsortedList) div 5)"/>

    <xsl:for-each select="($unsortedList)[position() &lt;= $nbCol]">
      <!--xsl:sort select="."/-->
      <xsl:variable name="here" select="position()"/>
      <tr>
        <xsl:call-template name="TDcompetence">
          <xsl:with-param name="competence"
select="$unsortedList[$here+$nbCol*0]"/>
        </xsl:call-template>

        <xsl:call-template name="TDcompetence">
          <xsl:with-param name="competence"
select="$unsortedList[$here+$nbCol*1]"/>
        </xsl:call-template>

        <xsl:call-template name="TDcompetence">
          <xsl:with-param name="competence"
select="$unsortedList[$here+$nbCol*2]"/>
        </xsl:call-template>

        <xsl:call-template name="TDcompetence">
          <xsl:with-param name="competence"
select="$unsortedList[$here+$nbCol*3]"/>
        </xsl:call-template>

        <xsl:call-template name="TDcompetence">
          <xsl:with-param name="competence"
select="$unsortedList[$here+$nbCol*4]"/>
        </xsl:call-template>
      </tr>
    </xsl:for-each>
  </table>


The sort is in comments because it do not work since I access the
value with a position into the $unsortedList variable directly and not
through the for-each which could sort.

Thank you.
