RE: [xsl] Get the maximum of a set of values

["Babos, Andras" <ababos@xxxxxxxxxxxxx>]

Hi Birgit,

That's an interesting one... Try calling this template (lines might wrap
around):

  <xsl:template name="GetMaxValue">
    <xsl:param name="startIndex" select="1"/>
    <xsl:param name="maxValue" select="0"/>

    <xsl:variable name="leftOver" select="count (index/entry) -
$startIndex"/>

    <xsl:choose>
      <xsl:when test="$leftOver &lt; 1">
        <xsl:variable name="lastNumber" select="document (concat (string
(index/entry[position () = last ()]/xml), '.xml'))/entry/item/@number"/>

        <xsl:choose>
          <xsl:when test="$maxValue &gt; $lastNumber">
            <xsl:value-of select="$maxValue"/>
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="$lastNumber"/>
          </xsl:otherwise>
        </xsl:choose>
      </xsl:when>
      <xsl:otherwise>
        <xsl:variable name="currentValue" select="document (concat
(string (index/entry[position () = $startIndex]/xml),
'.xml'))/entry/item/@number"/>

        <xsl:call-template name="GetMaxValue">
          <xsl:with-param name="startIndex" select="$startIndex + 1"/>
          <xsl:with-param name="maxValue">
            <xsl:choose>
              <xsl:when test="$maxValue &gt; $currentValue">
                <xsl:value-of select="$maxValue"/>
              </xsl:when>
              <xsl:otherwise>
                <xsl:value-of select="$currentValue"/>
              </xsl:otherwise>
            </xsl:choose>
          </xsl:with-param>
        </xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
