Hi Flo,

No problem. Just c&p the files below. The method being used is yet another
variant of Muenchian grouping, should you have encountered that term
already..


Your source xml, slightly modified to contain a root

<?xml version="1.0" encoding="UTF-8" ?>
<root>
<day date="01.03.2004">
   <users>1</users>
   <gv name="Offerte Neu">
      <hits>2</hits>
      <activity name="Ermittlung eines Produktes">
         <hits>2</hits>
      </activity>
   </gv>
   <gv name="SimulatorWeb">
      <hits>1</hits>
      <activity name="SimulatorDummy">
         <hits>1</hits>
      </activity>
      <activity name="Ermittlung eines Produktes">
         <hits>3</hits>
      </activity>
   </gv>
   <gv name="CIS">
      <hits>1</hits>
      <activity name="Vertrags Anzeige">
         <hits>1</hits>
      </activity>
      <activity name="Vertrags Suche">
         <hits>1</hits>
      </activity>

   <gv name="Muster">
      <hits>11</hits>
      <activity name="Muster">

   <gv name="Mahninfo">

      <activity name="Mahninfo">

The XSL solution I propose:

<?xml version="1.0" encoding="UTF-8" ?>

<xsl:stylesheet version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xmlns:ext="http://exslt.org/common"
        extension-element-prefixes="ext" />

<!-- key to approach activities by day and activity-name -->
<xsl:key name="acts-day-name" match="activity"
         use="concat(ancestor::day/@date,@name)" />

<xsl:template match="root">
  <xsl:apply-templates />
</xsl:template>

<xsl:template match="day">
  <!-- variable containing all distinct activity names
       for the day being processed -->
  <xsl:variable name="vacthelp"
         select="gv/activity[generate-id(.)=
           generate-id(
             key('acts-day-name', concat(
               current()/@date, @name)
                )[1])]" />

  <!-- variable containing the sum of hits for the current day
       for the activities in the $vacthelp variable -->
  <xsl:variable name="vacts">
    <xsl:for-each select="$vacthelp">
      <xsl:for-each select="$vacthelp">
        <activity name="{@name}">
          <hits>
        <xsl:value-of
select="sum(ancestor::day/gv/activity[@name=current()/@name]/hits)"/>
          </hits>
        </activity>
      </xsl:for-each>
  </xsl:variable>

  <xsl:value-of select="concat('&#x0A;',@date,'&#x0A;')" />
  <xsl:apply-templates select="ext:node-set($vacts)/*">
    <xsl:sort select="hits" data-type="number" order=descending" />
  </xsl:apply-templates>

</xsl:template>

<xsl:template match="activity">
  <xsl:value-of select="concat(.,' : ', hits,'&#x0A;')" />
</xsl:template>

</xsl:stylesheet>
