Re: [docbook-apps] Specify XHTML "<a title=..." in "<ulink ..."?

["Bob Stayton" <bobs@sagehill.net>]

I'd suggest customizing the whole template with match="ulink" from 
xhtml/xref.xsl.  It is only 35 lines long, and you could put the title 
attribute on the <a> element rather than a span.  Wouldn't that give you 
better behavior in browsers to display the title when hovering?

You could also take the title text from the url value or the text value of 
the ulink if it contains text nodes.  Using xreflabel instead of role is an 
option as well, although that is not the intended semantics for xreflabel. 
Something like this (untested):

<xsl:template match="ulink" name="ulink">
  <xsl:param name="url" select="@url"/>
  <xsl:variable name="link">
    <a>
      <xsl:apply-templates select="." mode="class.attribute"/>
      <xsl:if test="@id or @xml:id">
        <xsl:attribute name="id">
          <xsl:value-of select="(@id|@xml:id)[1]"/>
        </xsl:attribute>
      </xsl:if>
      <xsl:attribute name="href"><xsl:value-of 
select="$url"/></xsl:attribute>
      <xsl:if test="$ulink.target != ''">
        <xsl:attribute name="target">
          <xsl:value-of select="$ulink.target"/>
        </xsl:attribute>
      </xsl:if>
 <!-- *************  add these three lines ************ -->
      <xsl:if test="string-length(@xreflabel) != 0">
        <xsl:attribute name="title"><xsl:value-of 
select="@xreflabel"/></xsl:attribute>
      </xsl:if>
      <xsl:choose>
        <xsl:when test="count(child::node())=0">
          <xsl:value-of select="$url"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:apply-templates/>
        </xsl:otherwise>
      </xsl:choose>
    </a>
  </xsl:variable>

  <xsl:choose>
    <xsl:when test="function-available('suwl:unwrapLinks')">
      <xsl:copy-of select="suwl:unwrapLinks($link)"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:copy-of select="$link"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
