XSL 1.0 str-tolower Template

We’ll add a couple variables and a template to the strings.xsl stylesheet.

<!-- translation for lowercase-->
<xsl:variable name="lcletters" select="'abcdefghijklmnopqrstuvwxyz'"/>
<xsl:variable name="ucletters" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

<xsl:template name="str-tolower">
  <xsl:param name="str"/>
  <xsl:value-of select="translate($str, $ucletters, $lcletters)"/>
</xsl:template>

And here’s a new UT to add to strings.test.xsl:

<xsl:call-template name="assert">
  <xsl:with-param name="expected" select="'@apple1'"/>
  <xsl:with-param name="actual">
    <xsl:call-template name="str-tolower">
      <xsl:with-param name="str" select="'@ApPlE1'"/>
    </xsl:call-template>
  </xsl:with-param>
</xsl:call-template>
