processing style inside verbatim in XML

processing style inside verbatim in XML

[-- Attachment #1: Type: text/plain, Size: 1004 bytes --]

Hello,

Is there any simple way to typeset the following example properly in ConTeXt?

I have an example of text that has to obey lines and spaces, but I
would like to apply some color to make it more readable. The
attachment contains an example of HTML which displays fine in my
browser, and it should look similar with ConTeXt.

I have problems with literal typesetting of <span class=...> (that
should have applied style instead), but maybe I only have wrong
settings in my parser.

When I use \xmlsetfunction{main}{pre}{lxml.displayverbatim}, then I
cannot color the numbers. When I use, according to Wolfgang's
suggestion,

\startxmlsetups pre
\setuplines[style=mono,space=yes]
\startlines
\xmlflush{#1}
\stoplines
\stopxmlsetups

then all the spaces are eaten up by XML parser (or somewhere else), so
that I don't get the desired result. Any ideas about this?

I'm also sending a self-contained example with \setuplines which
doesn't really work in the desired way.

Thank you very much,
    Mojca

The next beta will provide two extra flushers. The following patch to 
your example seems to work ok then.

\startxmlsetups all:html
	\xmlsetsetup{main}{head|h1|pre|span}{*}
\stopxmlsetups

\xmlmapval{span}{n}{\bf\red}

\startxmlsetups span
     \start
         \xmlval{span}{\xmlatt{#1}{class}}{}
         \xmlflush{#1}
     \stop
\stopxmlsetups

\startxmlsetups pre
     \start \tttf
    %\xmlflush{#1}
    %\xmlflushlinewise{#1}
     \xmlflushspacewise{#1}
     \stop
\stopxmlsetups
