Hi folks,
The main reason I've been quiet lately is that I've been working on a
prototype XML 1.1 implementation (look for a prototype in a week or so).
In order to avoid lots of version checks in the main-line code, or lots of
calls to super methods in the XML 1.1 code, I'm developing new Entity,
Document and DTD scanners, extending from the current implementations; I
want to use the current impls (unchanged as much as possible) on 1.0 docs,
the new ones on 1.1 docs.
One way to achieve this is to use a special scanner at the front of the
pipeline who's sole purpose is to figure out what kind of document the
parser is dealing with and then dispatch appropriate scanners to do the
actual scanning. (This could also be done by a configuration, but since
this relies on rather intimate interactions with the entity manager and
existing scanners, this strikes me as highly unclean).
The changes Elena's already made to facilitate scanning/namespace binding
help, since they allow this new scanner to rework the document pipeline.
But the DTD pipeline isn't modifiable in the same way.
So I'd like to propose modifying XMLDTDSource and XMLDTDHandler in much the
same way as XMLDocumentSource and XMLDocumentHandler were already modified.
That is, add
public XMLDTDHandler getDTDHandler();
to XMLDTDSource and
public void setDTDSource(XMLDTDSource source);
public XMLDTDSource getDTDSource();
to XMLDTDHandler.
Thoughts?
Cheers,
Neil
