    Only show div if alias has content... What am I doing wrong?

    Hi Umbracians

    I have a problem using the if-test statement... I have an image slider in one of my templates, which uses the XSLT you see below. The images are created as sub-nodes of the node they should be shown in... And it works fine, until I try to tell the XSLT that it should only show the "imageText" div when the alias "contentPicture" is filled out... The "contentPicture" is an alias on the picture document type.

    I dont know what I am doing wrong here... Can someone please help me out?


    <xsl:for-each select="$currentPage/* [@isDoc and string(umbracoNaviHide) != '1']">

         <li class="squareRandom">
                <div style="background-image: url({picture}); width: 650px; height: 300px; padding: 50px 0 0 30px">

                     <xsl:if test="data [@alias = 'contentPicture'] != ''">
                          <div class="imageText" style="width: 400px; ">
                                <xsl:value-of select="contentPicture" disable-output-escaping="yes"/>
                          </div>
                    </xsl:if>
                </div>
         </li>
      
    </xsl:for-each>

     

     

    Kind regards from Denmark

    Hi Mikkel,

    Since your if block is inside a foreach and you want to refer to the "current" image node, you'll want to use the current() XSLT function:

    <xsl:if test="current()/data [@alias = 'contentPicture'] != ''">

    Hi Mikkel,

    Am not sure i really understood what you asked but you can try chaning the your test to something like

      <xsl:choose>
         <xsl:when test="data [@alias = 'contentPicture'] !='' ">
                   <div class="imageText" style="width: 400px; ">
                                <xsl:value-of select="contentPicture" disable-output-escaping="yes"/>
                          </div>
         </xsl:when>
     <xsl:otherwise>
          <!--  Remove the DIV  -->
     </xsl:otherwise>
    </xsl:choose>

    Hi Mikkel,

    The test you're performing uses the old XML Schema - you can do it like this:

    <xsl:for-each select="$currentPage/*[@isDoc][not(umbracoNaviHide = 1)]">
    <li class="squareRandom">
        <div style="background-image: url({picture}); width: 650px; height: 300px; padding: 50px 0 0 30px;">
            <xsl:if test="normalize-space(contentPicture)">
                <div class="imageText" style="width: 400px;">
                    <xsl:value-of select="contentPicture" disable-output-escaping="yes" />
                </div>
            </xsl:if>
        </div>
    </li>
</xsl:for-each>
