how to read whole xsd schema

[Kris Wolff]

Hi list,

i have a question, that might be a stupid one, but i can not figure out, 
if its even work with xerces-j or not.
I have a xsd and i want to build a map like
element -> (can have)  element              -> with attributes( foo, bar )
                                       or element         -> with 
attributes(foo)
                                                                  -> 
(can have) element
                                                                                           
or element
                                       or element

and so on. Maybe a hashtable with the keys [attributes] ans [elements] 
for each element. That is not imortent, importnt is that i have to read 
the schema and store the informations about elements, attributes and 
types in a diffrent format inside the memory.

I tried to play around with the xs.QueryXs example, but i only get the 
root element. I tried to read docu, goole, and so on, but i can't find 
any example how to dump all elements in the order the xsd descripes.

For example, i have these code:
XSModel model = schemaLoader.loadURI(argv[0]);
XSNamedMap map = model.getComponents(XSConstants.ELEMENT_DECLARATION);
if (map.getLength() != 0) {
   System.out.println("*************************************************");
   System.out.println("* Global element declarations: {namespace} name ");
   System.out.println("*************************************************");
   for (int i = 0; i < map.getLength(); i++) {
        XSObject item = map.item(i);
        System.out.println("{" + item.getNamespace() + "}" + 
item.getName());
   }
}

witch shows me the right root element of a valid xml, descripes in the 
xsd. But how to get the next level. How can i get all elements that are 
allowd inside the root-element?

can someone post me a example or point me into the right direction, please.


best regards,
kris
