Hi Nik, I'm using grouping by date by  the Munchean method on a couple of sites. My approach is this:

http://blackpoint.dk/umbraco-workbench.aspx?Snippet=/umbraco-workbench/xslt/grouping--distinct-values.aspx

In this example I'm using a formatted date string as the key to group from, but you have any option. If you cannot work it out, I can try to adapt the method to your purpose - just let me know. Now I have to take the kids to kindergarden...

Hi,

@Tommy, the strange this is I CAN get it to work in dev but not production. So weird, and I actually use that grouping on other macros a swell (by month/year). I've abandoned this for now as I have to move on. I'll dig in deeper using this method at later time to see if I can figure it out. 

@Chriztian, thanks! I think that is exactly what my problem is. I'll give it a test and let you know. Appreciate the insight!

Best,
Nik

Not meaning to hijaak this thread, but I don't see that there was a resolution.  Below is my latest attempt.  The code works great for content below currentpage but fails for content in sibling nodes.  I am getting every node for the entire site.

  <xsl:for-each select="$currentPage/preceding-sibling::* | $currentPage/following-sibling::* [@isDoc][(generate-id()=generate-id(key('years', Exslt.ExsltDatesAndTimes:year(publicationDate))[1]))]">
    <xsl:sort select="publicationDate" order="descending"/>

    <h3><strong><xsl:value-of select="Exslt.ExsltDatesAndTimes:year(publicationDate)"/></strong></h3>
    
    <xsl:for-each select="key('years',Exslt.ExsltDatesAndTimes:year(publicationDate)) [(generate-id()=generate-id(key('months', Exslt.ExsltDatesAndTimes:monthname(publicationDate))[1]))]">
      <xsl:sort select="publicationDate" order="descending"/>

      <div style="margin-left:10px;">
        <h3><xsl:value-of select="Exslt.ExsltDatesAndTimes:monthname(publicationDate)"/></h3>
    
        <xsl:for-each select="key('months',Exslt.ExsltDatesAndTimes:monthname(publicationDate))">
          <xsl:sort select="publicationDate" order="descending"/>

          <div style="margin-left:10px;">
            <div style="width:64px; float:left;"><xsl:value-of select="Exslt.ExsltDatesAndTimes:formatdate(publicationDate,'MM/dd/yy')"/></div>
              <div style="margin-left: 64px;"><p><xsl:value-of select="@nodeName"/>
                </p></div>
            </div>
        </xsl:for-each>
      </div>
    </xsl:for-each>
    <br />
  </xsl:for-each>

Hi all,

I am trying to categorize or group my press releases based on the year of publishing.When i am using key 'year' (i.e; using formatdatetime )the results are not coming. and when using key 'uniquedate' duplicate years are appearing,can anyone let me know what is the error?

<xsl:output method="xml" omit-xml-declaration="yes"/>

  <xsl:param name="currentPage"/>
  <xsl:key name="uniqueDate" match="PressRelease" use="pressPublishDate"/>
  <xsl:key name="year" match="PressRelease" use="umbraco.library:FormatDateTime(pressPublishDate,'YYYY')"/>
  <xsl:key name="kNewsByY" match="PressRelease" use="Exslt.ExsltDatesAndTimes:year(pressPublishDate)"    />
 
  <xsl:template match="/">

    <xsl:for-each select="$currentPage/child::*[generate-id() = generate-id(key('year', umbraco.library:FormatDateTime(pressPublishDate,'YYYY'))[1])]">
      <xsl:value-of select="substring(pressPublishDate, 1, 4)"/>

     <br/>
    </xsl:for-each>
    <div class="subnavTabs clearfix" id="subNavTabs">
      <ul>
        <xsl:apply-templates select="$currentPage/child::*[generate-id() = generate-id(key('uniqueDate', pressPublishDate)[1])]" mode="PressRelease">
          <xsl:sort select="pressPublishDate" order="descending" />
        </xsl:apply-templates>
      </ul>
     
    </div>
 
    <!--<xsl:for-each select="$currentPage/child::*">
      <xsl:value-of select="pressPublishDate"/>

      <xsl:value-of select="substring(pressPublishDate, 1,4)"/>
      <br/>
    </xsl:for-each>-->

  </xsl:template>
  <xsl:template match="PressRelease" mode="PressRelease">
    <xsl:variable name="PublishDate">
      <xsl:value-of select="substring(pressPublishDate, 1, 4)" />
    </xsl:variable>

    <xsl:variable name="DivId" select="concat('Div',$PublishDate)" />

    <li>
      <xsl:attribute name="id">
        <xsl:if test="$PublishDate = '2010'">
          <xsl:text>current</xsl:text>
        </xsl:if>
      </xsl:attribute>

      <a href="javascript:Toggle();">
        <xsl:attribute name="onclick">
          <xsl:value-of select="concat('ShowTab(',$DivId,',this);')"/>
        </xsl:attribute>
        <xsl:value-of select="$PublishDate"/>
      </a>
    </li>

  </xsl:template>
