Hi,
is there any code that creates an XMLSchema instance from its XML
representation? I.e. is there a method like "public static XSDSchema
parse(InputStream src)" that reads an XML file containing an XML schema
and create the appropriate XMLSchema instance? I had a quick look at the
source code but I didn't find anything like this.

Michael,
Did you look at this yet?
http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/xsd- home/docs/javadoc/org/eclipse/xsd/util/XSDPrototypicalSchema .html#printSchema(java.lang.String)
If you really need to create an instance directly from an input stream,
that's possible too:
Resource xsdSchemaResource =
resourceSet.createResource(URI.createDeviceURI(xsdSchemaURI) );
xsdSchemaResource.load(inputStream, Collections.EMPTY_MAP);

Sorry if I still don't get it ... I had a look at the class you suggested
and the code sippet below. Doesn't this code kind of de-serialize an
XSDSchema that has previously been saved? I'm looking for a way to create
an XSDSchema from its XML representation.
The class you suggested creates two example schemas by manually creating
every XSDComponents with Java code. It's it possible to provide an XML
file with your example schema and just load and XSDSchema from this file?

Michael,
The specific link I gave you is for a sample printSchema method that given the URI of a schema, i.e., the URI of a document containing a serialized XML representation of a schema, will print it, E.g.,
prototypicalSchema.print("file:/x:/myschema.xsd")
will load and print the indicated schema.
Your question implied that you had a stream already, so I showed how you could change the code in the sample to use an existing stream rather using the URI of an existing document. Didn't your question about having a stream imply that you have a serialized XML representation already? If you have a DOM node, you can create
an XSDSchema object (from the factory) and call setNode to populate the XSD model implied by that DOM. Maybe this is what you are asking?

I finally manged to read and print my schema from an InputStream :-)
However, it didn't work with Resources, probably because my Classpath is
incomplete (plus: my code has to run outside of Eclise). As a work-around,
I just loaded the DOM tree and used the schema's setElement method:
doc = readDOM(inputStream); // use xerces to load DOM tree
schema = XSDFactory.eINSTANCE.createXSDSchema();
schema.setElement((Element) doc.getFirstChild());
Here's my next problems: how can I get ElementDeclaration objects for this
schema? I tried
schema.getElementDeclarations()
which returned an empty list ...
Thank you for you patience!

Michael,
The xsd.test plugin is designed to be a complete working example that demonstrates both headless execution and standalone execution. It includes scripts in the test subdirectory to drive the tests. The script xsd-standalone-test.bat will be relevant to you, since it drives a main method via a CLASSPATH. Getting the CLASSPATH
right is very important, including the xsd.resource.jar, since it contains the schema for schemas, and nothing works without it. The file XSDMainTest.java has more details (maybe too many). It's best to start with something that's already working and slim it down from there...
You really need to use a ResourceSet if you want imports and includes to resolve; they work by demand loading new resources into the set...

Michael,
The specific link I gave you is for a sample printSchema method that given the URI of a schema, i.e., the URI of a document containing a serialized XML representation of a schema, will print it, E.g.,
prototypicalSchema.print("file:/x:/myschema.xsd")
will load and print the indicated schema.
Your question implied that you had a stream already, so I showed how you could change the code in the sample to use an existing stream rather using the URI of an existing document. Didn't your question about having a stream imply that you have a serialized XML representation already? If you have a DOM node, you can create
an XSDSchema object (from the factory) and call setNode to populate the XSD model implied by that DOM. Maybe this is what you are asking?

I finally manged to read and print my schema from an InputStream :-)
However, it didn't work with Resources, probably because my Classpath is
incomplete (plus: my code has to run outside of Eclise). As a work-around,
I just loaded the DOM tree and used the schema's setElement method:
doc = readDOM(inputStream); // use xerces to load DOM tree
schema = XSDFactory.eINSTANCE.createXSDSchema();
schema.setElement((Element) doc.getFirstChild());
Here's my next problems: how can I get ElementDeclaration objects for this
schema? I tried
schema.getElementDeclarations()
which returned an empty list ...
Thank you for you patience!

Michael,
The xsd.test plugin is designed to be a complete working example that demonstrates both headless execution and standalone execution. It includes scripts in the test subdirectory to drive the tests. The script xsd-standalone-test.bat will be relevant to you, since it drives a main method via a CLASSPATH. Getting the CLASSPATH
right is very important, including the xsd.resource.jar, since it contains the schema for schemas, and nothing works without it. The file XSDMainTest.java has more details (maybe too many). It's best to start with something that's already working and slim it down from there...
You really need to use a ResourceSet if you want imports and includes to resolve; they work by demand loading new resources into the set...
