[NTG-context] How to do code listings & sections from XML (AsciiDoc)

[Mojca Miklavec via ntg-context]

Hi,

Hans helped me out with some asciidoc processing a while ago.

I played a bit further, but I'm currently facing two minor issues:

(a) I don't know how to turn program listing (verbatim code) from xml
to (perhaps, vim-based) syntax highlighting (but most importantly, to
make sure that line breaks work properly)

(b) some section titles are missing


Ad (a). The source that looks similar to this:

<programlisting language="cpp" linenumbering="unnumbered">
int main()
{
    return 0;
}
</programlisting>

should be converted into some kind of equivalent of

% on top
\usemodule[vim]
\definevimtyping [CPP] [syntax=cpp]

\startCPP
int main()
{
    return 0;
}
\stopCPP

In the attachment I have the source document (test.adoc), the
generated docbook xml that should be further processed, and test.tex
that one processes to get the final pdf.

Any hints would be greatly appreciated.
