Hi,

ThanksÂfor your suggestions. I know AH is better but alas, I am using FOP.

Still stuck,

M.

If you are using AH Formatter, you can map the generic font family names
to specific fonts per script. [1]

"contains(' ja ', parent::type)" is true only when the string ' ja '
(including its space characters) contains the text content of the <type>
parent element of the <indexentry>. [1]Â There's several reasons why
that won't happen.

If you are generating <indexdiv> to group <indexterm>, then <indexterm>
isn't the parent element anyway.

One solution would be:

  <xsl:when test="ancestor::index/@type = 'ja'">

Another would be a separate template for Japanese <indexentry>, if you
would find that clearer:

<xsl:template match="indexentry[ancestor::index/@type = 'ja']">
 Â<fo:wrapper font-family="'Zen Old Mincho'">
  Â<xsl:apply-templates/>
 Â</fo:wrapper>
</xsl:template>

(fo:wrapper [3] is mostly a way to add inherited properties without
generating an extra area in the area tree.)

If your template is in a module that imports (directly or indirectly)
the usual template for <indexentry>, you can do: [4]

<xsl:template match="indexentry[ancestor::index/@type = 'ja']">
 Â<fo:wrapper font-family="'Zen Old Mincho'">
  Â<xsl:apply-imports/>
 Â</fo:wrapper>
</xsl:template>

Or you could set the font in your template for <index>:

<xsl:template match="index[@type = 'ja']">
 Â<fo:wrapper font-family="'Zen Old Mincho'">
  Â<xsl:apply-imports/>
 Â</fo:wrapper>
</xsl:template>
