Xslt snippet – Left pad a string

A quick xslt template to left pad a value:

<xsl:template name="prepend-pad">
  <!-- recursive template to right justify and prepend the value with whatever padChar is passed in   -->
  <xsl:param name="padChar"> </xsl:param>
  <xsl:param name="padVar"/>
  <xsl:param name="length"/>
  <xsl:choose>
    <xsl:when test="string-length($padVar) &lt; $length">
      <xsl:call-template name="prepend-pad">
        <xsl:with-param name="padChar" select="$padChar"/>
        <xsl:with-param name="padVar" select="concat($padChar,$padVar)"/>
        <xsl:with-param name="length" select="$length"/>
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="substring($padVar,string-length($padVar) - $length + 1)"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
