[XML-SIG] While we're on the subject of xmlproc, DTDs and validation ...

I'd like to have a very fast and simple parser that can do
validation. I'm looking at:
- Using (or stealing parts of) xmlproc to parse DTDs,
- Using pyexpat,
- Writing a C thing that does the validation using
data structures (possibly derived from data structures)
produced by xmlproc.
- Writing a simple C thing that plugs into the C
validator, which plugs into pyexpat and takes tables of
start and end tag handlers and processes XML to produce
I've modified pyexpat so that it will spit out the DTD info.
(I plan to post an updated pyexpat that implements the full
C expat interface defined in the latest stable expat release,
unless someone beats me to it. ;)
I find that if I tell xmlproc to parse a file containing only
a DTD, it will build the DTD related data structures for me, but:
- I wonder if there is or should be a tool designed
just to do this. Maybe there already is one that I've
- Can I rely on the data structures created by the current
I'd like to have a tool for processing DTDs independent of
- To make it possible to bolt validation onto non-validating
- To separate implementation of validation from implementation
of basic parsing and from application object building code.
For example, I think handlers that build application objects
can be alot simpler if they don't have to check validity.
- Allow applications to provide DTDs for documents that don't
have them (e.g. xml-rpc marchals).
