You might want to take a look at Earl Hood's perlSGML [1]. This, as
its name suggests, is a Perl module which parses SGML DTDs and
documents.
It allows you to do things like:
use SGML::DTD;
$dtd = new SGML::DTD;
open (DTDFILE, $dtdfilename) || die "Can't open $dtdfilename";
$dtd->read_dtd(\*DTDFILE);
@elements = $dtd->get_elements(0);
@top_element = $dtd->get_top_elements();
foreach $e (@elements) {
print "<dtdelement gi='$e'>\n";
@parents = $dtd->get_parents ($e);
print "<dtdparents>\n";
foreach $pe (@parents) {
print "<dtdelemref id='", lc($pe), "'>\n";
}
print "</dtdparents>\n";
@content = $dtd->get_base_children ($e, 1);
[...]
[blah blah blah]
All the best,
Norman
