[Dblatex-users] Using olink to reference a chapter

[Richard W. <wal...@gm...>]

I'm having problems using olink to reference a chapter.

The target.db file is generated (as per the dblatex manual) using the HTML
version of the DocBook styles.
The relevant bit of my target.db file is:

<div element="chapter" href="#chapter-passwords" number="2"
targetptr="chapter-passwords">
<ttl>Passwords</ttl><xreftext>Chapter 2, <i>Passwords</i></xreftext>

(So the the chapter name is surrounded by "i" tags.)

When I reference this with an olink and process with dblatex,
I only see the text "Chapter 2, ".  So the name of the chapter is lost,
apparently because of the <i> element around it.

I can make the chapter name appear in the PDF by overriding the
markup used for target.db, thus:

  <xsl:template match="chapter|appendix" mode="insert.title.markup">
    <xsl:param name="purpose"/>
    <xsl:param name="xrefstyle"/>
    <xsl:param name="title"/>

    <xsl:choose>
      <xsl:when test="$purpose = 'xref'">
  <!-- begin of i element was here -->
        <xsl:copy-of select="$title"/>
  <!-- end of i element was here -->
      </xsl:when>
      <xsl:otherwise>
        <xsl:copy-of select="$title"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

But actually I _would_ like the chapter name to appear
in italics, to match what I see when I process the document
to produce HTML output.

Inserting text nodes for "\emph{" and "}" in the above template doesn't work,
as the generated PDF then contains those strings literally.
So I can't see how to make this work.
