Re: [docbook] mediaobject fileref troubles

[Tobias Reif <tobiasreif@pinkjuice.com>]

[this is more of a docbook-apps@lists.oasis-open.org post, but the 
original post and question was mainly about the input thus the thread 
should be appropriate for docbook@lists.oasis-open.org]

Hi Patrick,

you could also use XSLT 2.

If you want to continue to use the current docbook.sf.net XSLTs, you 
could resolve references to external files in a simple preprocessing step.

For example, you could run your sources through something like

<xsl:transform
   version="2.0"
   xmlns="http://www.w3.org/1999/XSL/Transform">

<template match="node() | @*">
   <copy>
     <apply-templates select="@* | node()" />
   </copy>
</template>

<template match="textdata[@fileref]">
   <!--
   I'm sure there is a much simpler way
   -->
   <variable name="dir_abs"
     select="replace(base-uri(/),'[^\/]+$','')"/>
   <!--
   AFAICS, basically resolve-uri()
   concatenates if @fileref is relative, and
   leaves unchanged if it's absolute
   -->
   <variable name="file_abs"
     select="resolve-uri(@fileref,$dir_abs)"/>
   <copy-of select="unparsed-text($file_abs,'utf-8')"/>
</template>

</transform>

The template works for me (Saxon 7.5.1), but the whole XSLT has not been 
run or tested.

See an example at
http://www.pinkjuice.com/joocs/doc/ (URL will change)
(currently last test, #14)

Input:
http://www.pinkjuice.com/joocs/test/input.dbx

<section><title>Inserted File</title>
   <example><title>Counter</title>
   <programlisting><textobject><textdata
       fileref="counter.rb"/></textobject></programlisting>
   </example>
</section>


Output:
http://www.pinkjuice.com/joocs/test/output.xhtml

<div class="section jcs-toplevel">
   <h3 class="title">Inserted File</h3>
   <!-- example not yet fully supported -->
   <h3 class="title">Counter</h3>
   <pre><code>1.upto(ARGV[0].to_i) do |i|
   puts i
end
</code></pre>
</div>
