RE: [xsl] how to do i18n with parameter substitution

[George James <GeorgeJ@xxxxxxxxxxxxxxx>]

After sleeping on it I was able to answer my own question, however I suspect
that that p1 and p2 templates could be generalised to handle any named
parameter, but haven't figured that out yet.

  <xsl:template name='i18n'>
    <xsl:param name='caption'/>
    <xsl:choose>
      <xsl:when
test='document("phrases.xml")/phrases/phrase/target[../@key=$caption/@key
and lang($language)]'>
        <xsl:apply-templates
select='document("phrases.xml")/phrases/phrase/target[../@key=$caption/@key
and lang($language)]' mode='parameters'>
          <xsl:with-param name='caption' select='$caption'/>
        </xsl:apply-templates>
      </xsl:when>
      <xsl:otherwise>
        <xsl:copy-of select='$caption' />
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

  <xsl:template match='target' mode='parameters'>
    <xsl:param name='caption'/>
    <xsl:apply-templates mode='parameters'>
      <xsl:with-param name='caption' select='$caption'/>
    </xsl:apply-templates>
  </xsl:template>

  <xsl:template match='p1' mode='parameters'>
    <xsl:param name='caption'/>
    <xsl:value-of select='$caption/p1/@value'/>
  </xsl:template>

  <xsl:template match='p2' mode='parameters'>
    <xsl:param name='caption'/>
    <xsl:value-of select='$caption/p2/@value'/>
  </xsl:template>
