preprocessor for DTDs?

[nobody]

hello!

do you know of any (free) preprocessor able to deal with DTDs?

I'dlike to do things as
#define with_b
...
<!ELEMENT a (#PCDATA)>
<!ELEMENT c (#PCDATA)>
#ifdef with_b
<!ELEMENT b (#PCDATA)>
#endif
...
#ifdef with_b
<!ELEMENT x (a+,
#ifdef with_b
b*,
#endif
c)>
...
like with the good old C preproc.
I'm aware of the INCLUDE/IGNORE "feature" but I'm missing dynamic evaluation of this statements.

thx for any hints, andreas

Two good preprocessors:

http://math.polytechnique.fr/cmat/auroux/prog/gpp.html http://www.ross.net/funnelweb/

I'dlike to do things as
#define with_b
...
<!ELEMENT a (#PCDATA)>
<!ELEMENT c (#PCDATA)>
#ifdef with_b
<!ELEMENT b (#PCDATA)>
#endif
...
#ifdef with_b
<!ELEMENT x (a+,
#ifdef with_b
b*,
#endif
c)>

I would use any language, or even better: Perl, i.e.:

use strict;
use warnings;

sub with_b
{ return "
<!ELEMENT a (#PCDATA)>
<!ELEMENT c (#PCDATA)>
"; }

if( defined with_b )
{ print "
<!ELEMENT b (#PCDATA)>
"; }

This (perl) is even better than any pre-processor - you could easily query a database or a remote web page, if you want to make you DTD depending on its contents or arbitrarily complex functions of both. There are even CPAN modules to help you to parse DTDs, so you could also analyze another DTD with that "preprocessor" and then generate your DTD depending on this.

do you know of any (free) preprocessor able to deal with DTDs? found one that nicely fits the bill:
Double Helix DHpp - a standalone text preprocessor at

Why not use... the good old preproc. It's called cpp on my system.

C preprocessors expect C syntax, at least those I tried out couldn't preproc non C sources ;-(
