Re: [xsl] How do I change a XSL style sheet to group data together under one heading

["kieters c" <kieters@xxxxxxxxxxx>]

Good day,

Thank you for the information.  I have changed it accordingly and nothing 
seems to happen.  I have checked to see if I did everything, checked for any 
inconsistancies like an extra bracket but still nothing happened.  I replace 
every instance of "sample_date_time" with "concat(sample_date_time, 
cp_name)".

This is what I have done
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  version="1.0">

  <xsl:output method="xml" indent="yes"/>

  <!-- the key determines (here) what to group by -->

  <xsl:key name="sample" match="sample" use="concat(sample_date_time, 
cp_name)" />

  <xsl:template match="/">
      <submission imis_company_code="0001843309" ws_name="LENNOX">
          <xsl:apply-templates />
      </submission>
  </xsl:template>

  <xsl:template match="dataroot">

      <!-- the actual 'group by' construct -->
      <xsl:for-each select="sample[generate-id() = 
generate-id(key('sample', concat(sample_date_time, cp_name)[1])]">
          <xsl:copy>
              <!-- date-time must become an attribute -->
              <xsl:apply-templates select="concat(sample_date_time, 
cp_name)" />

              <!-- find all samples with equal date time -->
              <xsl:apply-templates select="key('sample', 
concat(sample_date_time, cp_name))" />
          </xsl:copy>
      </xsl:for-each>
  </xsl:template>

  <!-- match the sample's that are grouped -->
  <xsl:template match="sample">
      <result>
          <xsl:apply-templates select="*[not(self::concat(sample_date_time, 
cp_name))]"  />
      </result>
  </xsl:template>

  <!-- any direct child of 'sample' must be turned into an attribute -->
  <xsl:template match="sample/*">
      <xsl:attribute name="{name()}">
          <xsl:value-of select="."/>
      </xsl:attribute>
  </xsl:template>

</xsl:stylesheet>

Regards.

Hennie
