Reading XSD in Java

[saddist]

Hello,

I have an xsd file, and I would like to read its structure and display it as a JTree.
I know there are DOM and SAX parsers, but Im looking for something that would detect simple/complex types etc.
Is there any library able to do this? I know C# has XMLSchema, but I have to write in Java.

Cheers,

Charles

Try this, I believe what you aksed for is this. Posting code instead, just in case link no longer works:

Not sure of the legality of this, have not tried it myself, but I trust IBM:-) Here is the link:
