I've tried to do this, you don't need a schema parser and description object, but you will have to tamper with the MSV source code a bit to get what you want. (in this approach you'll be stuck with MSV's representation of the schema and will have to look at the source code to get what you want).
1. You'll have to add a method to get the top level schema element inside the com.sun.msv.verifier.jarv.SchemaImpl class. 2. Once you get this element, there is a visit() call that you can make on all such Schema Elements, with your own custom visitor. You can use the visitor to traverse the schema and create your own datastructure binding together all the schema descriptions MSV parsed for you. (I used a hashtable with every Object mapping to a list of subtag-describing objects and a list of attribute-describing objects : this is in the context of Xml Schema, something similar should be possible in the context of DTD's etc : I dunno) - Vivek On Fri, 26 Apr 2002, Christopher M.
