Re: SAX Parser & DOCTYPE statement

[Michael Rafael Glavassevich <mr...@engmail.uwaterloo.ca>]

Hello Anthony,

If you specify a public ID in the doctype declaration, you also need to
specify a system ID. Have a look
at the XML rec: http://www.w3.org/TR/REC-xml#NT-ExternalID. You can make
the system ID an empty string. It just cannot be null. Keep in mind that
the system ID is a URI, and thus it doesn't necessarily have to point to
the location of your DTD. It is just an identifier. You can invent your
own scheme such as jar://my.dtd, and register your own EntityResolver
which understands how to read 'jar' URIs. So if that serves your purpose,
you don't need a public ID.

Hope that helps.
