    Don't show if empty

    I have a page which displays project items like so:

    http://prntscr.com/79k8od

    There are two problems I'm facing.

    1. If a project group has no children, it shouldn't show the title for that group (the h2 right after the loop).
    2. After there's an empty group, the row is wrapping everything else like so: (I guess this might be fixed if the title doesn't show for an empty group)

    http://prntscr.com/79ka5h

    Here's the folder structure:

    http://prntscr.com/79kcsb (The folders alias is ProjectsGroup)

    And the current code:

    Hi Devin,

    I think something like this will work for you. I must admit that it´s been a while since I have written XSLT :-)

    <xsl:if test="./child::*[@isDoc] > 0">
         <h2><xsl:value-of select="@nodeName"/></h2>
    </xsl:if>
    

    Hope this helps,

    /Dennis

    Hi Dennis,

    Thanks for trying but that returns NULL and hides every heading.

    Hi Devin,

    You just need to only iterate the groups that have children, so try changing the for-each to this:

    <xsl:for-each select="$projectGroup[*[@isDoc]]">
        <h2><xsl:value-of select="@nodeName"/></h2>
        <div class="row">
            <xsl:apply-templates select="*[@isDoc]" mode="projectItem"/>
        </div>
    </xsl:for-each>

    As the rep says... "You rock!" +1

    I knew it would be something simple but just couldn't get it!

    Thanks mate.

    Is there also a way to include a statement to check if the "ecmLink" textstring field is empty in the for-each? I dont' want projects showing up if they don't contain a link.

        <xsl:for-each select="$projectGroup[*[@isDoc]]">
                <h2><xsl:value-of select="@nodeName"/></h2>
                <div class="row">
                    <xsl:apply-templates select="*[@isDoc]" mode="projectItem"/>
                </div>
        </xsl:for-each>

    Hi Devin,

    Yes - of course:

    <xsl:for-each select="$projectGroup[*[@isDoc][normalize-space(ecmLink)]]">
    

    (The normalize-space() function removes all whitespace, so an accidental space or tab character doesn't count as content)

    Hi Devin,

    I think that you can do the check with something like this.

      <!-- wrap project title with link -->
                    <xsl:if test="$ecmLink !=''">
                        <a class="downloadLink" href="{$ecmLink}">
                            <div class="projectTitle">
                                <xsl:value-of select="@nodeName"/>
                                <!-- small attachment icon -->
                                <div class="downloadIcon"><img src="/images/icons/download.png" /></div>
                            </div>
                        </a>
                      <xsl:if>
    

    Then it will only output this markup if the link is not empty

    Hope this helps, and works.

    /Dennis

    Thank you both for helping. I did try add the if test != '' check but it didn't work. I guess because as Chriztian said, the white space. Works perfectly though Chrizt thanks a lot.
