RE: additional question: FO subscript Revisited

Thanks Jeni.

The list of characters may get larger and larger over time.

The reason it's duplicating the information is that you're doing two
things with the same string at the same time - first substituting the
2 and then substituting the 5. The two choices need to be separate.
Also, you need to make sure that you call the template on the
substring *before* the 2, just in case it contains a 5:

<xsl:template name="replace2s">
  <xsl:param name="string" select="string()" />
  <xsl:variable name="subscript2">
    <fo:inline baseline-shift="sub" font-size="6px">2</fo:inline>
  </xsl:variable>
  <xsl:variable name="subscript5">
    <fo:inline baseline-shift="sub" font-size="6px">5</fo:inline>
  </xsl:variable>
  <xsl:choose>
    <xsl:when test="contains($string, '2')">
      <xsl:call-template name="replace2s">
        <xsl:with-param name="string"
                        select="substring-before($string, '2')" />
      </xsl:call-template>
      <xsl:copy-of select="$subscript2" />
      <xsl:call-template name="replace2s">
        <xsl:with-param name="string"
                        select="substring-after($string, '2')" />
      </xsl:call-template>
    </xsl:when>
    <xsl:when test="contains($string, '5')">
      <xsl:value-of select="substring-before($string, '5')" />
      <xsl:copy-of select="$subscript5" />
      <xsl:call-template name="replace2s">
        <xsl:with-param name="string"
                        select="substring-after($string, '5')" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise><xsl:value-of select="$string" /></xsl:otherwise>
  </xsl:choose>
</xsl:template>

If you keep adding things to the list of characters that need to be
replaced, then you'd be better off with a different approach, so let
us know if that's the case.

I hope that helps,

Jeni
