Søg etter node

Hei
Jeg er nybegynner i XSLT så kan noen hjelpe meg med bruke $foo istedenfor /displaying her, eg. $translations/$foo

<xsl:variable name="fob" select="'displaying'"/>
<xsl:value-of select="$translations/displaying" />

eg. full kode
<?xml version="1.0"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nbsp  "&#160;">
]>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:include href="languageArticle.xsl (kopi)"/>
    <xsl:variable name="language" select="/site/language"/>
    <xsl:output method="html"/>
    <xsl:template match="/">
   
        <xsl:for-each select="/verticaldata/contents/content">
            <xsl:value-of select="name()"/><br/>
            <xsl:variable name="fob" select="'displaying'"/>
            <xsl:value-of select="$translations/displaying" />
            <hr/>
        </xsl:for-each>
   
    </xsl:template>
</xsl:stylesheet>
