Subject: re: Subject: docbook.xsl and epub indexing

You might find my ongoing guide of docbook-epub tricks to be helpful
(though it's not well-organized)


There is a parameter index.links.to.section which lets you link to a
specific part of the page
. But I found a kind of bug in that:

Here's what I wrote about indices and epub:

HTML indices for Docbook don’t use page numbers, but indicate the
section title. That can be cumbersome. The solution is (for now) to
give a titleabbrev element for every title and then prevent the TOC
builder from using the titleabbrev in the TOC instead of the original
title. Until there is a parameter to disable this, you can customize
the template named ‘toc.line’ in html/autotoc.xsl to change

<xsl:apply-templates mode="titleabbrev.markup" select="." />


 <xsl:apply-templates select="." mode="title.markup"/>

Now that I look at this more closely, I  see that the epub stylesheet
uses xhtml-1.1, so the proper file to edit would be

HTML indices in epub don’t work well when you use a SECONDARY element
under INDEXTERM element (i.e., most of the time).
index.links.to.section determines whether the index link will go to
the exact place in the section or simply to the top of the section.
The default value for this parameter is 1 (which means the link will
go to the section and not the exact location). Unfortunately, changing
it to 0 will make the link go specifically to the specific location in
the text; however, it will create duplicate links in the index: one
to the value of the PRIMARY element, and the other to the value of the
SECONDARY element.  I ended up leaving the value of this parameter to
the default (i.e, 0) and indicating on the heading of the index that
it will go to the section, not the exact place. “Topics, listed by
Chapter & Section”.  Another option is to not use the SECONDARY value
at all and change the parameter value to 1.  It’s a tradeoff. (More
about this bug https://sourceforge.net/tracker/index.php?func=detail&aid=3202612&group_id=21935&atid=373747
). 4/1/2011 Update. When you convert from epub-to-Kindle,  kindlegen
massacres the index. It cannot process the secondary element only the
primary element; it can only deal with one level of index terms. I
think it relates to the way Kindle handles definition lists.


Subject: docbook.xsl and epub indexing

I transformed a docbook to epub using docbook.xsl, which went very
well using python and LXML (I am new to all of this). The index points
to chapter headings (how useful is that?). Is there a way to revise
the XSL to have the index point to the location in the text?
