Hi Shannon

Could you provide us with the example you have tried to use?

If I remember correctly you need to turn the currentdate and the dates to compare with into numbers. So for instance todays date would be 201101260000 - And then you should be able to compare the other dates using the same number format.

Hi Shannon,

Few weeks ago I had the same problem.

Check http://our.umbraco.org/forum/developers/xslt/15697-Hide-nodes-which-haven't-been-updated

Here's the XSLT

<xsl:param name="currentPage"/>
    
    <xsl:variable name="currentDate" select="umbraco.library:CurrentDate()"/>
    <xsl:variable name="updated" select="$currentPage/@updateDate"/>
    <xsl:variable name="difference" select="Exslt.ExsltDatesAndTimes:seconds(Exslt.ExsltDatesAndTimes:difference(umbraco.library:FormatDateTime($updated, 'yyyy-MM-dd') , Exslt.ExsltDatesAndTimes:date())) div 86400"/>
    
<xsl:template match="/">
  
    <xsl:choose>
      <xsl:when test="$difference &gt;= 1">
        show'm
      </xsl:when>
      <xsl:otherwise>
        hide'm
      </xsl:otherwise>
    </xsl:choose>

</xsl:template>

</xsl:stylesheet>

Maybe it will help you.

So this should work:

  <xsl:param name="currentPage"/>
    <xsl:variable name="currentDate" select="umbraco.library:CurrentDate()"/>
    <xsl:variable name="updated" select="$currentPage/@postDate"/>
    <xsl:variable name="difference" select="Exslt.ExsltDatesAndTimes:seconds(Exslt.ExsltDatesAndTimes:difference(umbraco.library:FormatDateTime($updated,
 'yyyy-MM-dd') , Exslt.ExsltDatesAndTimes:date())) div 86400"/>
    
  <xsl:template match="/">
    <div id="slider" class="news_banner" >
      <xsl:for-each select="$currentPage/ancestor-or-self::*//BlogPost [@isDoc and position() &lt; 6 and $difference &lt;=3]">
        <xsl:sort select="pageViewCount" order="descending" />
        <xsl:if test="blogImage != ''">
          <xsl:variable name="crop" select="umbraco.library:GetMedia(blogImage, 0)/crops/crops/crop [@name='NewsBanner']" />
          <xsl:if test="$crop/@url != ''">
            <a href="{umbraco.library:NiceUrl(@id)}"><img src="{$crop/@url}" alt="{@nodeName}" title="#htmlcaption{@id}"  /></a>
          </xsl:if>
        </xsl:if>
      </xsl:for-each>
    </div>
    <xsl:for-each select="$currentPage/ancestor-or-self::*//BlogPost [@isDoc and position() &lt; 6]">
      <xsl:if test="blogImage != ''">
        <xsl:variable name="crop" select="umbraco.library:GetMedia(blogImage, 0)/crops/crops/crop [@name='NewsBanner']" />
        <xsl:if test="$crop/@url != ''">
          <div id="htmlcaption{@id}" class="nivo-html-caption"><xsl:value-of select="@nodeName" /> - <a href="{umbraco.library:NiceUrl(@id)}">Read more...</a></div>
        </xsl:if>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

This should work in retreving blog posts but I am missing something

Hi Shannon,

Try something like this:

<xsl:for-each select="$currentPage/ancestor-or-self::*//BlogPost [@isDoc]">
   <xsl:sort select="pageViewCount" order="descending" />
   <xsl:if test="blogImage != '' and position() < 6 and $difference <=3">
      <xsl:variable name="crop" select="umbraco.library:GetMedia(blogImage, 0)/crops/crops/crop [@name='NewsBanner']" />
      <xsl:if test="$crop/@url != ''">
         <a href="{umbraco.library:NiceUrl(@id)}"><img src="{$crop/@url}" alt="{@nodeName}" title="#htmlcaption{@id}"  />a>
      xsl:if>
   xsl:if>
xsl:for-each>

If this doesn't work you can set the variables $update and $difference after the sort command.

I figured out something different.
