Re: Parsing DTDs and converting from DTD to XML schema

[Bart Read <ba...@uk.lionbioscience.com>]

Hi All,

 

 

I have a question concerning parsing DTDs.  Obviously when you use
Xerces with validation turned on it parses any DTD that is referenced.
It also parses internal subsets etc.  However, what I want it to do is
to parse JUST a DTD (and any DTDs that it references and so forth in a
recursive fashion).  So, if I give it an XML document I want it to parse
the DTD (this is no problem and I can get the results I'm looking for
now just by turning on validation) but sometimes I just want to give it
a DTD to start off with, and I'm unsure how to go about this.

 

Coupled to this I would like to take a DTD and turn it into an XML
schema.  I'm aware that I can use trang for this, but unfortunately it
doesn't handle internal subsets, so is there a way to take my DTDGrammar
and turn it into a SchemaGrammer, and having done this can I then write
this schema out to a file?

 

I've been digging through the source code for the 2.4.0 release but
there is rather a lot so I'd be extremely grateful if anybody out there
could give me a few pointers.

 

 

Many thanks,

Bart Read

Could you not use an a tool like XMLSpy to convert dtd to schema? There are
quite a few tools that do this. Please check the references/tools on the w3
xml schemas page.

Thanks
