Source code pretty printer with DocBook or XML output?

Is there some source code pretty printer out there that is able to generate DocBoo开发者_JAVA技巧k, or at least XML output from my C sources?

I want to include some good looking source code examples in my DocBook document.

I'm not sure what you mean by a pretty-printer that generates XML, but if you want code examples in DocBook documents to be nicely colourized when transformed to HTML or FO/PDF output, take a look at XSLTHL. This is an XSLT extension module (written in Java) that decorates the content of <programlisting> elements.

For details on using XSLTHL with with the DocBook XSL stylesheets, see http://docbook.sourceforge.net/release/xsl/current/doc/html/highlight.source.html.
