I've been messing around with this today, and I think I've figured out the problem (although no solution, yet). Since DocBook XML is XML (well, duh), it has a dbcentx.mod, which is different from the one in the DocBook SGML package. the differences show up in the ENTITY declarations. SGML allows for a simple mapping of entities to PUBLIC identifier, while XML requires both a PUBLIC -and- a SYSTEM identifier. I'm not sure if it is kosher to share entities between SGML and XML (they're currently included in the sgml-common package). If they can't be shared, then the creation of an xml-common package will be necessary. If they -can- be shared, then we need to figure out a way to determine where the sgml-common package has put the entities, so that we can put the SYSTEM identifier in properly. So, is that clear as mud, and which guesses am I completely wrong about? Yes, we need an xml-common package I think. I just tried using the entities from the sgml-common package with my home-brew docbook-dtd412-xml package, and they don't work. :-( I'll try to look at an xml-common package today. Things should end up installed in /usr/share/sgml/xml-iso-entities-8879.1986 if I'm not mistaken. I'm stuck trying to figure out what the patch to dbcentx.mod should look like, but maybe it will be clear after I have an xml-common package. The right solution is to switch to XML catalogs for XML resources at some point: http://www.oasis-open.org/committees/entity/ I will try to implement XML Catalogs into libxml before the next Red Hat release, then we will have a standardized and scalable solution for XML cataloging needs that can be installed in /etc/xml/catalog and /usr/share/xml/ Daniel Done. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.16-22 i586; en-US; 0.8.1) Gecko/20010422 Description of problem: I've been looking into making some DocBook XML stuff work on Red Hat Linux 7.0+ (I've got the rawhide DocBook stuff installed). I'm currently using libxml2-2.3.8 and libxslt-0.9.0, both compiled locally. I've also unzipped Norm's XSL stylesheets (1.29) into /usr/share/sgml/docbook/xsl-stylesheets/ How reproducible: Always Steps to Reproduce: 1. run libxslt /usr/share/sgml/docbook/xsl-stylesheets/docbook/html/docbook.xsl /path/to/file.xml 2.observe output 3. Actual Results: /usr/share/sgml/docbook/xml-dtd-4.1/dbcentx.mod:53: error: Space required after the Public Identifier ISOamsa PUBLIC "ISO 8879:1986//ENTITIES Added Math Symbols: Arrow Relations//EN ^ /usr/share/sgml/docbook/xml-dtd-4.1/dbcentx.mod:53: error: SystemLiteral " or ' expected ISOamsa PUBLIC "ISO 8879:1986//ENTITIES Added Math Symbols: Arrow Relations//EN ^ Expected Results: Should use xsltproc to transform said XML document into HTML Additional info: There are actually a slew of errors similar to the one above, all of which corespond to one of the lines that was changed in the dbcent.mod, or some entity which can't be found because of those changes. I took a look at the way that things get set up, and I see that make install isn't installing the XML versions of these entity files. I'm not sure if the XML entities are different from the SGML ones, so I can't say if that's the right behaviour. I'm pretty convinced that I don't understand how dbcent.mod should be pointing to the entities, so I'm giving up on providing a fix, at least for tonight.
