How to display taxonomy value using xslt?

Question

I have created an item template in ItemStyle.xsl to assign it to the CQWP.

My template is:

<xsl:template name="DepartmentsTemplate" match="Row[@Style='DepartmentsTemplate']" mode="itemstyle">

<xsl:variable name="DisplayTitle">
        <xsl:call-template name="OuterTemplate.GetTitle">
            <xsl:with-param name="Title" select="@Title"/>                                    
        </xsl:call-template>
    </xsl:variable>  

    <a onclick="sayHello('{@Title}')"> <xsl:value-of select="@Department" disable-output-escaping="yes"></xsl:value-of></a>
</xsl:template>

Here the value I am displaying in @Department is of type managed metadata field. It displays output like: Department 2|c98ce851-88fd-41bc-a013-4a69dd6bae66 but I want to display Department 2 only.

What should I do?

Answer 1

Try using the XSLT substring-before function:

<xsl:value-of select="substring-before(@Department,'|')" disable-output-escaping="yes">

Answer 2

Dave's solution fixes your problem with assumption your data always contains a |. If you want to make your solution a little more robust you could also write this:

<xsl:value-of select="substring-before(concat(@Department, '|'), '|')" disable-output-escaping="yes"></xsl:value-of></a>

This will also work in the case that the string does not have a | in it.
