referring to floats in xml

referring to floats in xml

[R. Ermers]

[-- Attachment #1.1: Type: text/plain, Size: 1681 bytes --]

Dear All,

My xml docbook file contains a number of graphics. Some are regular figures, some are edgefigures. I have two questions in this respect.

A. referring to floats

\placeedgefigure
[\xmlatt{#1}{id}]
{\xmlfirst{#1}{/caption}}
{\framed[frame=off]{\setlayer[graphics]{\xmlfirst{#1}{/imageobject}}}}

\definefloat[edgefigure][figure]
\setupfloat[edgefigure]
[leftmargindistance=-\innercombitotal,rightmargindistance=-\outercombitotal,
default={outer,low,long}, criterium=.65\textwidth,numbering=no]

<mediaobject id="fig:cow" role="edgefigure">
          <imageobject>
            <imagedata scale="500" fileref="cow.jpg"/>
          </imageobject>
        </mediaobject>

I now wonder how to refer to these floats. That is, referring through <xref linkend="cow"/> is not difficult to implement, but for some reason the mapping of the id is not that obvious. I tried it like this:

\startxmlsetups xml:mediaobject:edgefigure
\placeedgefigure
[\xmlatt{#1}{id}]
{\xmlfirst{#1}{/caption}}
{\framed[frame=off]{\setlayer[graphics]{\xmlfirst{#1}{/imageobject}}}}
\stopxmlsetups

The log file says:
references      : unknown reference [][fig:cow]

The reference is not solved.


B. edgefigures and regular figures

The document contains two types of figures.

\xmlsetsetup{#1}{mediaobject[@role='fig']}{xml:mediaobject:fig}
\xmlsetsetup{#1}{mediaobject[@role='edgefigure']}{xml:mediaobject:edgefigure}

I have noticed that when <mediaobject> contains both the attributes id and role, such as the cow example, the figure is considered a regular figure automatically and will not typeset as an edgefigure.


Regards,

Robert

Understanding these snippets is difficult without a minimal working 
example.

Try

\placeedgefigure
   []
   [\xmlatt{#1}{id}]
   {....}
   {....}

Please provide a minimal working example.

Thanks, Aditya, The first problem is adequately solved by adding []. I'll prepare an example for the second problem.

A related problem is referring to sections and other blocks.

<section id="sec:cows"><title>Cows</title>
<para>cows cows cows. As I told in <xref linkend="sec:cows"/></para></section>

The title is mapped as follows (lpath):
\xmlsetsetup{#1}{section/title}{xml:section/title}

\startxmlsetups xml:section:title
\section{\xmlflush{#1}}
\stopxmlsetups

The section is not mapped:
\startxmlsetups xml:section
\xmlflush{#1}
\stopxmlsetups

Adding [\xmlatt{#1}{id}] to xml:section:title does not work of course. Using [\xmlatt{#1}{id}] with xml:section puts the id before the \section command. I think one of the other commands has to be used in such a way that the id is flushed forward after the \section command.

Regards,

Robert

Map section to include both id and title. (Untested)

\startxmlsetups xml:section
\section[\xmlatt{#1}{id}]{\xmlfirst{#1}{/title}}
% or slightly better
% \section[\xmlattdef{#1}{id}{+}]{\xmlfirst{#1}{/title}}
% Then flush para separately
% \xmlall{#1}{/para}
% or
% \xmlconcat {#1} {/para} {\par}
% or better, add a contents tag around the contents
% <section> <title> ... </title>
%   <contents> ... </contents>
% </section>
% and then use
% \xmlfirst{#1}{/contents}

\stopxmlsetups

Thanks very much, Aditya for your advice. I really appreciate it. 
I tried your suggestions.

The section titles and numbers are doubled now, most likely due to other mappings that. The subsection and subsubsection titles need to be mapped as such, a generic mapping for all section heads is not feasible (I think).

This does not work, because the sections contain all kinds of elements, not just <para>. 
<section><blockquote/><section><para>text</para></section><para>text</para></section>

I tried \xmlall{#1} with other elements, but the result is a mess. I need an lpath symbol that refers to all underlying elements. I tried {+}, {*}, {//}, etc.

I had thought about this, but it would ruin the docbook structure of the document, and my editor programme would no longer accept it. The programme already complains about the change of <table to <cals:table. The typesetting of tables as part of the document is still a problem ...
