Re: [docbook-apps] color coding

1. How should I do the markup the xml? It's no problem to markup the

For the sake of syntax highlighting I would use <phrase role="keyword">, <phrase role="literal"> or something like that.

2. Is there some description how to change the xsl files in order to
   generate some appropriate output for html and pdf?

If you mark up your XML source as above you can then very easily customize template which is responsible for processing the phrase element to output appropriate HTML and FO code. See

I found pages by Lars Trieloff describing how he managed to get
Syntaxhighlighting to work with Saxon and jedit, but it seems this
method is depending on those programs and I'd prefer to do it with
emacs and xslt (apart from the hassle to program some appropriate java
code for support of this language). I didn't see the source files of
his web pages, but I guess, he didn't markup the xml at all and the
Highlighting was done automatically in Saxon using the jedit plugin for
identifying the styles to apply.

Yes. This is a big advantage of Lars's solution. It just works on unmodified DocBook source, you don't have to preprocess sourcecode listing to markup syntax highlighting there.

Although I could hardly find anything at all concerning DocBook and
Syntax highlighted output I think there must be a consistent way to
implement this without customizing the xml parser itself. Or is
DocBook the wrong way altogether?

No need for change in XML parser. I see two solutions to your problem:

1. Markup syntax highlighting codes explicitly in your source (of course this can be automated by some script or using Emacs htmlize function). Easy customization of stylesheets is then enough to get desired result.

2. Do the syntax highlighting on-the-fly during processing. In this case you must implement grammar (or at least regulat expression based rules) for your language directly in the XSLT or as an XSLT extension. This is harder to implement (but you can use Lars's implementation out-of-the-box) but easier to use IMHO.
