Hi,
I am trying to build tree from Schema. And I am able to build the tree
from schema.
But I am facing the problems if my schema has import/include schemas.
It is like A.xsd imported B.xsd and B.xsd imports C.xsd.
Say I have Element 'xa' defined in A.xsd and type="xbtype" which is
defined in B.xsd and in b.xsd the defination for 'xbtype' is defined as
type="xctype" and in C.xsd i have defined type for 'xctype'. but in parser
i am not able to get all the elements which are defined in C.XSD
Please help me to resolve this issue
Robert

Robert,
It will help me to know what you've tried. The XSD model really
supports both a syntactic view of the schema as well as the abstract
component model defined in the XML Schema specification. For example,
XSDSchema.getContents() will get you what's physically in the schema
whereas something like XSDSchema.getElementDeclarations will get you all
the elements logically part of the schema (via includes and imports).
It's also possible that you are having problems with imports and
includes not resolving because you've not loaded the schema with an
absolute URI; see the note about "How to get elements from the include
schemas" which is two notes up from this one in the newsgroup.

Hi Ed Merks,
Thanks for your response.
I have gone through that link But not able to solve my problem.
Brief Des about my problem is
I have A.XSD which Includes B.XSD and B.xsd includes C.XSD.
I am able to resolve entity type referenced in B.XSD But not from C.XSD
My Requirement is to build schema tree. I am sending you sample schemas
and code which I have used (modified for demo purpose).
with the current code I am getting this as output
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
Here the problem is Typedefination for element 'to' is defined in C.xsd
which is not resolved.
I should get some thing like this
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
/envelope/messageHeader/to/gln
Here is the code I have used

Robert,
When I ran this sample it produced:
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
/envelope/messageHeader/to/gln
I wonder if 99227 <https://bugs.eclipse.org/bugs/show_bug.cgi?id=99227>
solved the problem? Which version are you trying?

Hi Ed Merks,
Thanks for very quick response.
I am using XSD 2.0.0 plugin and eclipse 3.0.0
Can you suggest me which version of XSD plugin I have to use?.
We are using eclipse 3.0.0 and that I can't change as we are developing
all products in 3.0.0.
Thanks again for quick response
Robert.

Robert,
I'm not able to reproduce this on an old 3.0.1 (with EMF/XSD/SDO 2.0.1)
base I have kicking around either:
Maybe the problem was fixed in the 2.0.x stream. The 2.0.2 version of
EMF/XSD/SDO is a released supported version that should still work with
Eclipse 3.0.0.

Yes you are correct. This is fixed in 2.0.3 or may be before.

HI Ed Merks,
I am here again with new question.
My requirement is I have to copy main Schema file and imported/included
schema files from remote site.
I have another utility which will copy file from remote site to my local
disk if I send file name.
So first time I will send main schema file to my utility. So that I can
have main file in local disk.
Now my requirement comes here. I have to parse main schema file and get
Import/Include files list.
So when I load schema and validate I am getting getAllDiagnostics errors.
Because I do not have imported files (they are not resolved)
To get imported files I am using the below code. Please advise me weather
I am following right way or not ?
I am posting my code here. The below method prints import/include file
names.
Thanks
Robert
public String[] getImpIncList(String schemaFileName)throws IOException{
String impincList[];
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "xsd",
new XSDResourceFactoryImpl());
File file = new File(schemaFileName);
URI uri;
if (file.isFile())
{
uri = URI.createFileURI(file.getCanonicalFile().toString());
}
else
{
uri = URI.createURI(schemaFileName);
}
// Create a resource set, create a schema resource, and load the main
schema file into it.
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getLoadOptions().put(XSDResourceImpl.XSD_TRACK_L OCATION,
Boolean.TRUE);
XSDResourceImpl xsdMainResource =
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));
xsdMainResource.setURI(uri);
xsdMainResource.load(resourceSet.getLoadOptions());
// Get the first resource, i.e., the main resource and those that have
been included or imported.
Object resource = resourceSet.getResources().get(0);
if (resource instanceof XSDResourceImpl)
{
XSDResourceImpl xsdResource = (XSDResourceImpl)resource;
XSDSchema xsdSchema = xsdResource.getSchema();
xsdSchema.validate();
/*

if (!xsdSchema.getAllDiagnostics().isEmpty())
{
m_error_List = new ArrayList();

Robert,
Your code looks okay, but the problem is that the schema locations could
be relative URIs (needing to be resolved against the base URI of the
schema in which they occur) or could even be missing (for imports), in
which case the namespace itself is used as a location.
If you loaded the main remote file into a resource set, all the imports
and includes will resolve (to the correct relative locations). This
will fill the resource set up with all the schema resources you need.
You could look at the URI of each resource to know what file to copy
over and you have the complete list. This seems better.

Robert,
It will help me to know what you've tried. The XSD model really
supports both a syntactic view of the schema as well as the abstract
component model defined in the XML Schema specification. For example,
XSDSchema.getContents() will get you what's physically in the schema
whereas something like XSDSchema.getElementDeclarations will get you all
the elements logically part of the schema (via includes and imports).
It's also possible that you are having problems with imports and
includes not resolving because you've not loaded the schema with an
absolute URI; see the note about "How to get elements from the include
schemas" which is two notes up from this one in the newsgroup.

Hi Ed Merks,
Thanks for your response.
I have gone through that link But not able to solve my problem.
Brief Des about my problem is
I have A.XSD which Includes B.XSD and B.xsd includes C.XSD.
I am able to resolve entity type referenced in B.XSD But not from C.XSD
My Requirement is to build schema tree. I am sending you sample schemas
and code which I have used (modified for demo purpose).
with the current code I am getting this as output
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
Here the problem is Typedefination for element 'to' is defined in C.xsd
which is not resolved.
I should get some thing like this
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
/envelope/messageHeader/to/gln
Here is the code I have used

Robert,
When I ran this sample it produced:
/envelope
/envelope/messageHeader
/envelope/messageHeader/to
/envelope/messageHeader/to/gln
I wonder if 99227 <https://bugs.eclipse.org/bugs/show_bug.cgi?id=99227>
solved the problem? Which version are you trying?

Robert,
I'm not able to reproduce this on an old 3.0.1 (with EMF/XSD/SDO 2.0.1)
base I have kicking around either:
Maybe the problem was fixed in the 2.0.x stream. The 2.0.2 version of
EMF/XSD/SDO is a released supported version that should still work with
Eclipse 3.0.0.

Robert,
Your code looks okay, but the problem is that the schema locations could
be relative URIs (needing to be resolved against the base URI of the
schema in which they occur) or could even be missing (for imports), in
which case the namespace itself is used as a location.
If you loaded the main remote file into a resource set, all the imports
and includes will resolve (to the correct relative locations). This
will fill the resource set up with all the schema resources you need.
You could look at the URI of each resource to know what file to copy
over and you have the complete list. This seems better.
