Subject: Re: [docbook-apps] changing how xrefs to listings are rendered in PDF


thanks for answering.

I have introduced some changes to the asciidoc file I'm working with,
and now, docbook version which is generated, has all listings are
included in <example> tag, as you suggested, e.g.:

<example id="listing_some_id">
<title>Some Title</title>
<programlisting language="java" linenumbering="unnumbered">
some code here

In PDF this is rendered as "Example 5.1" and references (xref
linkend="listing_some_id"/>) are also rendered like "Example 5.1".
This is almost perfect, but I would like to have "Listing 5.1"

Could you please explain how to do this?

I tried to do the following:
<l:context name="xref-number-and-title">
        <l:template name="example" text="Listing %n"/>
but it did not help.

Regards / Pozdrawiam

>> Hi All,
>> I'm writing a book using Docbook and have an issue with how references
>> to listings are rendered in PDF version.
>> For example, my docbook file contains the following fragment:
>> <simpara>Blah blah blah as presented on listing <xref
>> linkend="listing_shortest_test"/>.</simpara>
>> <formalpara id="listing_shortest_test">
>> <title>One-Liner Test</title>
>> <para>
>> <programlisting language="java" linenumbering="unnumbered">
>> // some cool code here
>> </programlisting>
>> </para>
>> </formalpara>
>> In PDF version (generated with fop) xhref link to the listing is rendered

>> "Blah blah blah as presented on listing One-Liner Test."
>> I would like to look it differently, i.e. like this:
>> "Blah blah blah as presented on listing 3.1"
>> I have achieved similar thing with tables and figures (as discussed

>> <xsl:param name="local.l10n.xml" select="document('')"/>

>>    <l:context name="xref-number-and-title">
>>      <l:template name="table" text="Table %n"/>
>>    </l:context>
>>  </l:l10n>
