    useIfEmpty alternative for xslt

    XSLT

    Hi there,

    A while back someone suggested the following template code for me which I've been using quite a while:

    <umbraco:Item field="alternativeTitle" useIfEmpty="pageName" runat="server"></umbraco:Item>

    It uses the alternative title if it's set, otherwise it will use the page name instead.

    Now I would like to do the same in xslt, is this possible?

    Thanks!

    Hi SaphuA,

    You could write an XSLT extension to handle this in a single line, but to do it natively in XSLT, you can use an <xsl:choose>:

    <xsl:choose>
    <xsl:when test="string(data[@alias='alternativeTitle']) != ''">
        <xsl:value-of select="data[@alias='alternativeTitle']" />
    </xsl:when>
    <xsl:otherwise>
        <xsl:value-of select="@pageName" />
    </xsl:otherwise>
</xsl:choose>

    Cheers, Lee.

    Hi

    Yes it's possible to do with XSLT as well.

    You simply just make a choose section, which could look like this

    <xsl:choose>
    <xsl:when test="string-length('yourproperty') &gt; 0"><xsl:value-of select="yourproperty" /></xsl:when>
    <xsl:otherwise><xsl:value-of select="youralternativeproperty" /></xsl:otherwise>
    </xsl:choose>

    In the xsl:when you check if your primary field has any data. If it has you output the data. If it's empty the data from the alternative field is fetched instead.

    Hope this makes sense.

    /Jan

    @Jan, you know I was thinking when I posted mine... "wonder if anyone else is answering this at the same time?" ;-D  (I've voted for you!)

    Thanks for the replies. I marked Lee's post as answe since he was faster and I personally like casting to a string better than using string-length, although that isn't based on anything.

    Thanks!
