Hi,
A while ago Hans provided an example of typesetting a document from a
docbook source.
I'm attaching an over-simplified version of the initial module (a
somewhat more complete version exists, but it still needs lots of
work) and a minimum working example with XML.
I'm not sure how to extend the xml parser to support typesetting from
something like this:
<section xml:id="_hello_world_in_c_and_context">
<title>Hello World in C and ConTeXt</title>
<programlisting language="cpp" linenumbering="unnumbered">#include
<stdio.h>
int main()
{
     printf("Hello, World!\n");
     return 0;
}</programlisting>
<programlisting language="context" linenumbering="numbered">\starttext
Hello world!
\stoptext</programlisting>
</section>
Maybe using the vim module would be the right approach here (since the
built-in parser only has support for a limited set of languages), but
I'm not exactly sure about the implementation to achieve that goal.
I started with
\startxmlsetups xml:programlisting
     \dontleavehmode
     \startframedtext[background=color,backgroundcolor=lightgray]
     \obeylines
     \tt
     \xmlflush{#1}
     \stopframedtext
\stopxmlsetups
but something more is needed to properly handle new lines and to
properly pass the text to vim, for example.
Any hints welcome.
\startbuffer[demo]
<doc>
<pre type='tex'>
\def\whatever#1{[whatever #1]}
\ctxlua{print("okay")}
</pre>
<pre type='xml'>
<html>
     <b>bold</b>
</html>
</pre>
</doc>
\stopbuffer

\usemodule[scite]

\startxmlsetups xml:initialize
     \xmlsetsetup{#1}{doc|pre}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:initialize}

\startxmlsetups xml:doc
     \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:pre
     \blank
     \xmlprettyprint{#1}{\xmlattdef{#1}{type}{txt}}
     \blank
\stopxmlsetups

\starttext
     \xmlprocessbuffer{main}{demo}{}
\stoptext
