    Mailto in Xslt and what do to if empty?

    Hi guys,

    I have a DocumentType with a textstring. In the textstring there is an e-mail address.

    My xslt shows this textstring like this:

    <xsl:value-of select="data [@alias = 'rcMail']"/>

    No problem there, but! How to get it to be a Mailto-link instead of just the plain text. I have tried with an "a-tag" with mailto around, but umbraco tells me i have an error in the xslt.

    I know it is probably simple, but can't figure it out! So how about just asking the experts, which i've just done!

    ----

    If empty?
    Another thing is, if there is not email-address in my textstring - the string should not be shown at all (It leaves whitespace even though it is empty)
    I have tried with an "if test" - without much luck. 

    Can you point me in some direction?

    Best regards,
    Brian

    Hi,

     

    <xsl:if test="string(data[@alias = 'rcMail']) != ''">
      <a href="mailto:{string(data [@alias = 'rcMail'])}">name</a>
    </xsl:if>

     

    Cheers,

    /Dirk

    Hi Dirk,

    Thanks alot! The mailto was as easy as i thought, but i simply could not figure it out...

    I was a bit fast with the solution though! The if test removes the textstring no matter if it is EMPTY or not!

    What to do?

    Show when not empty, remove when empty :)

    best regards,
    Brian

    I tried a choose instead. This works in the way that it shows the text when it is there, but it still leaves whitespace, when empty!

     

     

    <xsl:choose>
<xsl:when test="string(data[@alias = 'rcline4']) != ''">
<!-- If empty, nothing will show! -->
</xsl:when>
<xsl:otherwise>
<!-- It will show! -->
<xsl:value-of select="data [@alias = 'rcLine4']"/><br/>
</xsl:otherwise>
</xsl:choose>

    Any suggestions?

    It turned out that it really was an "xsl:if test" that worked. The following code work = it displays the textstring when there is any text in it, and removes the textstring/whitespace when it is empty:

    <xsl:if test="string(data[@alias = 'rcLine4']) != ''">
<xsl:value-of select="data [@alias = 'rcLine4']"/>
</xsl:if>

    rcLine4 is the alias of my textstring. This was exactly what Dirk wrote, so I was a bit quick - i must have made some sort of misspelling etc

    Best regards,
    Brian
