I have a multilangual website setup, in which the xslt checks for the current language by getting the name of the rootnode. It then has to append the current language to a property alias. I've tried to do it with concat, but it gives me text instead of a value.

So, I have a $lang and a value for $node/prodDescription and I want the the complete string to be:

<xsl:value-of select="$node/prodDescription_NL"/>

Is that possible?

Some explanation:

<xsl:template match="/">

    <xsl:variable name="lang" select="$currentPage/ancestor-or-self::*[@level = '2']/@nodeName"/>

    <xsl:value-of select="$lang"/>

    <xsl:if test="$currentPage/products/MultiNodePicker/nodeId">

      <xsl:for-each select="$currentPage/products/MultiNodePicker/nodeId">

        <xsl:variable name="node" select="umbraco.library:GetXmlNodeById(.)" />

        <div class="dealer">
          <h3>
            <xsl:value-of select="$node/pageTitle"/>
          </h3>
        </div>
      </xsl:for-each>

    </xsl:if>

  </xsl:template>
