Re: [docbook-apps] how to add a style attribute inside a P element? (Kindle insanity!)

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

Hi Robert,
The mechanism in the stylesheet that lets you customize class attributes can also be 
used to add other attributes such as style or width.  Most element templates include 
something like this:

<xsl:apply-templates select="." mode="class.attribute">

If not, then it has this:

<xsl:call-template name="common.html.attributes">

which in turn applies templates in mode="class.attribute".  The default template in 
that mode is in html/html.xsl:

<xsl:template match="*" mode="class.attribute">
  <xsl:param name="class" select="local-name(.)"/>
  <!-- permit customization of class attributes -->
  <!-- Use element name by default -->
  <xsl:attribute name="class">
    <xsl:apply-templates select="." mode="class.value">
      <xsl:with-param name="class" select="$class"/>
    </xsl:apply-templates>
  </xsl:attribute>
</xsl:template>

As you can see, that template generates an attribute whose name is "class" and whose 
value is determined using mode="class.value", which is the mode I usually advise 
people to customize when they need to change the class value for an element.

But you could expand this template to include additional <xsl:attribute> elements to 
generate additional attributes, such as style or width.  Since this is a mode, you can 
write separate templates for each element that needs to generate different extra 
attributes, using the match attribute on the template to select a specific XPath 
pattern.  How you determine the values from your content is up to you.  As Nic 
suggests, role attribute could be used.

Hi Robert

I've been doing some of the same things you are doing here. I'm not convinced that are 
right about the Kindle indenting (I'm looking at some titles I worked on and we've 
used css classes for the indent and it's working just fine).

For the width, I postprocess. I'm working on a set of scripts for a client at the 
moment that takes an EPUB and does some mappings for the Kindle. I may be able to make 
them available to you (the client is often happy for code written for them to be put 
into the public domain).

There is no reason why you couldn't do both the things you are discussing here using a 
customisation though. You could use a template that operates on role attributes 
perhaps.
