What version of umbraco are you using?

Are you checking whether $currentPage/data[@alias='relatedLinks'] contains a value?

Hi Matt,

Post somemore of the XSLT so we can see what's going on...

Hi,

Yeah, I'm checking if there are any "related links". I'm using the custom repeatible content control so the XML looks like this:

<items>
    <item>
        <data alias="alias1">value 1</data>
        <data alias="alias2">value 2</data>
    </item>
    <item>
        <data alias="alias1">value 3</data>
        <data alias="alias2">value 4</data>
    </item>
</items>

More XSLT if it helps:

    <xsl:variable name="relatedLinksCount" select="count($currentPage/data[@alias='relatedLinks']/items/item)"/>
    Value:<xsl:value-of select="$relatedLinksCount"/>

          <xsl:for-each select="$currentPage/data[@alias='relatedLinks']/items/item">
            <li>
              <div class="image">
                <a href="{data[@alias='relatedLinkUrl']}">
                  <img>
                    <xsl:attribute name="src">
                      <xsl:call-template name="ImageOrVideoThumbnail">
                        <xsl:with-param name="currentNode" select="umbraco.library:GetMedia(data[@alias='relatedLinkImage'],'false')"></xsl:with-param>
                        <xsl:with-param name="width">80</xsl:with-param>
                        <xsl:with-param name="height">55</xsl:with-param>
                        <xsl:with-param name="isMediaItem">true</xsl:with-param>
                        <xsl:with-param name="crop">&amp;crop=resize</xsl:with-param>
                      </xsl:call-template>
                    </xsl:attribute>
                  </img>
                </a>
              </div>
              <div class="text">
                <h4>
                  <a href="{data[@alias='relatedLinkUrl']}">
                    <xsl:value-of select="data[@alias='relatedLinkText']"/>
                  </a>
                </h4>
              </div>

            </li>
            
          </xsl:for-each>
          
          
        </ul>
      </div>
    </xsl:if>

Umbraco 4.1 btw.

Sorry that XSLT snippet was slightly incomplete, I missed out the <xslt:if> from just before the foreach that is causing it to break:

    <xsl:if test="$relatedLinksCount &gt; 0">

If I remove the test, it works, but adding it causes the xslt error.

Have you tried: 

 <xsl:variable name="relatedLinksCount" select="count($currentPage/data[@alias='relatedLinks']//item)"/>

Thanks, but that doesn't help. The thing is I can see the relatedLinksCount variable is working fine, I am outputting it and can see the value is set correctly. Its just the <xsl:if> that fails....

<xsl:if test="number($relatedLinksCount) &gt; 0">?

Failing that I will bow to the XSLT wizard that is Chriztian

Oh jeez. Got it. The problem was inside my XSLT was a small bit of logic that was getting some value from some other node, and I wasn't checking this one for emptiness.

I also omitted it from my code paste above, because I thought it was inconsequential and would add noise - so you had no chance of getting it.

My bad, really sorry for wasting your time, and thanks for your help !
