Re: XML::LibXML search path for DTDs

Let me rephrase:  I can work out where the DTDs will be.  I'm having trouble giving that path to LibXML.
- I can't put a path to the DTD into the XML file, because it will differ for various users.
- I can't put in a line like   $parser->parse_file ($xml_location, dtd_search_path => [ $dtd_location ]); 
     into my Perl code because, AFAICT, there is no 'dtd_search_path' option.

I've been using this kludge:
    my $xml_line = "<?xml version='1.0' encoding='utf-8'?>";
    my $dtd_line = "<!DOCTYPE pre SYSTEM '${dtd_location}/${type}.dtd'>";
    my $doc = $parser->parse_string ($xml_line . $dtd_line . $text);

but that has the side effect that any errors in the .xml are reported without the filename.

you can try using a combination of File::Spec (namely rel2abs), File::Basename (with
its dirname() function), the __FILE__ constant, $0 (see perlvar), etc. to
find the absolute path for the DTDs. Will this help?
