Generate XML document from Schema

[vidarno]

Hi!

I'm working on a simple xml editor in Java at the moment. It's purpose
is
to enable the user to store information about typically collected types
of
posessions, like books, movies (DVDs) and music (CDs). I want the
program
to be able to accept various forms of posessions, so if I later create
a new
Schema for a new type of posessions the GUI will adapt - This is much
like
the Xample editor which after opening an .xsd builds a user interface
based
on it.

What I'm wondering is how this is possible, I've tried scouring the
source code
of Xample to discover just how it parses the Schema files, but to no
avail, also
it seems the developer is not responding to emails (also the program is
"old").
All other programs with the same functionality seem to be closed-source
and/or
commercial - I want/need to know how it's done!

Is anybody out there able to help me out, point me in the right
direction?
I believe JAXB is not the correct way as it needs recompiling each time
you use
a new Schema, right?

Thanks for your time, I hope YOU can help me. If so, cupcakes and coco
might
be involved.

Sincerely,
Mandragor

An XML schema is itself an XML document. You can read it using an XML
parser, then write tools to interpret it and (attempt to) generate an
interactive entry system from it. A number of XML editors have attempted
to do exactly that, either by just imposing constraints on a tree editor
or by trying to take it all the way to forms (which is a more difficult
problem). Dealing with all the interactions is a pain, which is why we
haven't seen more examples of this.
