Re: DOCBOOK-APPS: color coding

That may be impractical. You really need to pre-process the code
listing to add markup for the syntax highlighting. (Trying to get XSLT
to do syntax highlighting by semantic analysis of the code listing is
probably more trouble than its worth.)

| How can i do this? Any help is greatly appreciated!

When I wanted to have syntax highlighted XML in a document I was
writing, I wrote prettyprint.pl (attached) that reads an XML document
and produces marked-up DocBook.

Then I added a little CSS to my HTML file:

tt.sgmltag-starttag    { color: #4080B0; }
tt.sgmltag-endtag      { color: #4080B0; }
tt.sgmltag-emptytag    { color: #4080B0; }
tt.sgmltag-sgmlcomment { color: #B02020; }
tt.sgmltag-xmlpi       { color: #0000F8; }
tt.sgmltag-genentity   { color: #686868; }
pre.programlisting     { background-color: #F0DCB0; }

Result: syntax highlighted XML.

Maybe something similar would work for your application.

prettyprint.pl

                                        Be seeing you,
