Re: [docbook-apps] Adding an icon before a chapter title -continuation

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

Hi,
I'm not quite clear on how your custom "chaptitle.title" template is being 
called.  I'm guessing that you have customized the titlepage spec file as 
described in my book:

http://www.sagehill.net/docbookxsl/TitleFontSizes.html#ChapterTitles

If so, then the $node variable in the template contains the chapter element, 
and you can use $node/@icon  to get at the attribute value.  The reason 
@icon didn't work is because the context node for the template is the 
chapter's title element, not the chapter.  How do I know that?  If you look 
in titlepage.templates.xsl, you will find now the original "component.title" 
template was called for a chapter:

<xsl:template match="title" mode="chapter.titlepage.recto.auto.mode">
<fo:block xmlns:fo="http://www.w3.org/1999/XSL/Format"; 
xsl:use-attribute-sets="chapter.titlepage.recto.style" font-size="24.8832pt" 
font-weight="bold">
<xsl:call-template name="component.title">
<xsl:with-param name="node" select="ancestor-or-self::chapter[1]"/>
</xsl:call-template>
</fo:block>
</xsl:template>

This template matches on title, which makes the title the context node for 
the call to "component.title".

I think if you had used parent::chapter/@icon  in your customization it 
would have worked as well.

Hi everybody,

what I am actually trying to do is the following:

<!-- Setting chapter title to separate number and label -->
<xsl:template name="chaptitle.title">
  <xsl:param name="node" select="."/>
  <xsl:variable name="id">
    <xsl:call-template name="object.id">
      <xsl:with-param name="object" select="$node"/>
    </xsl:call-template>
    </xsl:variable>


  <fo:block xsl:use-attribute-sets="chap.label.properties">
    <xsl:apply-templates select="$node" mode="label.markup"/>
  </fo:block>

  <fo:block xsl:use-attribute-sets="chap.title.properties">

    <fo:list-block provisional-distance-between-starts="1cm + 8pt"
                    provisional-label-separation="8pt">
      <fo:list-item>
          <fo:list-item-label end-indent="label-end()">
            <fo:block>
              <fo:external-graphic>
                <xsl:attribute name="src">
        <xsl:call-template name="fo-external-image">
          <xsl:with-param name="filename" select=concat('images', @icon, 
'.png'/>
        </xsl:call-template>
      </xsl:attribute>
              </fo:external-graphic>
            </fo:block>
          </fo:list-item-label>
          <fo:list-item-body start-indent="body-start()">
              <fo:block>
                <xsl:apply-templates select="$node" mode="title.markup"/>
              </fo:block>
          </fo:list-item-body>
      </fo:list-item>
    </fo:list-block>
  </fo:block>
</xsl:template>

An then in the xml file itself I set:

<chapter icon="advanced">
<title>Advanced Settings</title>
....
where "advanced" is the name of the PNG file in the 'images' folder. The 
question is how I can pass the variable icon value (in this case "advanced") 
to  my chapter template.

Thanks in advance!
Nancy


I would like to dynamically add an icon before a chapter title, with a 
possibility to change the icon file's name in the XML file itself, and not 
in the stylesheet. I would like to add the icon's filename in the chapter's 
tag itself (e.g. <chapter icon="internetconn"> and to pass this filename to 
the template that will add it to the rest of the file path (eg, 
concatenate('/images', @icon, '.png')

Please advise, how to extract the value of the "icon" variable and pass it 
to the "concatenate" part of the <fo-external graphic> template?



Thanks a lot!
Nancy
