How do I include an XML schema in an EMF model? [message #391028] Wed, 09 February 2005 20:48 Go to next message

I want to wrap an XML schema inside an XML document that will be represented
by an EMF model, and I'd like to have the schema part of the document
processed by XSD when I load the parent document into my model.

For example, assume I have a schema that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http://mydomain/test"
xmlns="http://mydomain/test"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="unqualified" attributeFormDefault="unqualified">
<xs:complexType name="RootElement">
<xs:sequence>
<xs:element name="properties" type="ConfigProperty" minOccurs="0"
maxOccurs="unbounded"/>
<xs:any namespace="http://www.w3.org/2001/XMLSchema"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="ConfigProperty">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="value" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:schema>

If I use that schema to generate an EMF model, I think the generated model
ought to be able to process a document that looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<test:RootElement xmlns:test="http://mydomain/test">
<properties>
<name>name1</name>
<value>value1</value>
</properties>
<xs:schema targetNamespace="http://mydomain/test"
xmlns="http://mydomain/test"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="unqualified"
attributeFormDefault="unqualified">
<xs:complexType name="RootElement">
<xs:sequence>
<xs:element name="properties" type="ConfigProperty" minOccurs="0"
maxOccurs="unbounded"/>
<xs:any namespace="http://www.w3.org/2001/XMLSchema"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="ConfigProperty">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="value" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
</test:RootElement>

In other words, the <xs:schema> element ought to be legal content for the
<xs:any> element in my schema. However, when I try to load the document it
complains about Feature 'schema' not found. (model/test.test, 10, -1).

The code that tries to load the document looks like this:

XSDPackageImpl.init();
TestPackageImpl.init();
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*",new
TestResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResource(URI.createDeviceURI(schemaURL),true) ;

Any suggestions?

Thanks,
John Sipher

John,

This is much easier said than done. A schema model instance must be
constructed from a DOM, so you need to create a DOM when parsing and
then use that to create the XSDSchema. Similarly, when serializing, you
need to get the DOM from the XSDSchema and serialize that. The folks
doing a WSDL model need to solve this problem, but that's been done by
making the WSDL model work much like the XSD model. Probably is you
look at how XSDResourceImpl implements doSave and doLoad, it will be
more clear how it works (and that you have a hard problem to solve.).

Ed,

Thanks for the quick response. For my purposes the solution is relatively
easy now that I know I'm not missing something easy in the original
approach. I did run across something that didn't work as I thought it
should from reading the XSD FAQ.

I think I should be able to do this to get empty resources that I can load.
// initalize packages
XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();
// set up resource registry

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test",n
ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd",ne
w XSDResourceFactoryImpl());
// get "empty" resources
ResourceSet resourceSet = new ResourceSetImpl();
TestResourceImpl testResource =
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
XSDResourceImpl xsdResource =
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));

In both cases resourceSet.createResource() returns null, and I'm not sure
why. I traced into it and it looks as if the resource factory registry
hasn't been initialized yet.

John

The "solution" to the original problem follows. Please let me know if
anyone sees problems with it (exception handling obviously needs to be
added).

String modelURL = args[0];
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new FileInputStream(modelURL));

ByteArrayOutputStream baos = new ByteArrayOutputStream();
Transformer transformer =
TransformerFactory.newInstance().newTransformer();

XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test",n
ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd",ne
w XSDResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
// TestResourceImpl testResource =
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
// XSDResourceImpl xsdResource =
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));
TestResourceImpl testResource = new
TestResourceImpl(URI.createURI("*.test"));
XSDResourceImpl xsdResource = new
XSDResourceImpl(URI.createURI("*.xsd"));
resourceSet.getResources().add(testResource);
resourceSet.getResources().add(xsdResource);

// get the embedded schema, load it into an XSDSchema instance, and add
it to the xsd resource
Element schemaElement =
(Element)document.getDocumentElement().getElementsByTagNameN S( "http://www.w3
..org/2001/XMLSchema","schema").item(0);
DOMResult domResult = new DOMResult(builder.newDocument());
transformer.transform(new DOMSource(schemaElement),domResult);
XSDSchema schema = XSDFactory.eINSTANCE.createXSDSchema();
schema.setElement(((Document)domResult.getNode()).getDocumen tElement());
xsdResource.getContents().add(schema);

// remove the schema from the original document and load the remainder
into the test resource.
document.getDocumentElement().removeChild(schemaElement);
transformer.transform(new DOMSource(document),new StreamResult(baos));
testResource.load(new
ByteArrayInputStream(baos.toByteArray()),resourceSet.getLoad Options());

John,

You should register "test" and "xsd", not "*.test" and "*.xsd". Note also that if the schema contains schemaLocation="..." where the ... is a relative path, it's important that the URI of the containing resource be an absolute path so that relative location can be interpreted properly. In that case "*.xsd" would not be so good and you might want to take the name of the actual location of the bigger file (modelURL) and append .xsd to it to create your "fake" XSD URI.

I also made a comment line below about the add of the resource being unnecessary since the createResource will already have added it...

This is much easier said than done. A schema model instance must be
constructed from a DOM, so you need to create a DOM when parsing and
then use that to create the XSDSchema. Similarly, when serializing, you
need to get the DOM from the XSDSchema and serialize that. The folks

Thanks Ed. Now another problem. =20

This works as long as the schema embedded in my model document is =
entirely self contained, but it breaks when the schema has <xs:import> =
elements. I assume the problem is that XSDResourceImpl() can't resolve =
relative schema locations when it's loading from a ByteArrayInputStream. =
Is there an easy way around that (maybe something I can set in the load =
options)?

Thanks,
John

John,

You should register "test" and "xsd", not "*.test" and "*.xsd". Note =
also that if the schema contains schemaLocation=3D"..." where the ... is =
a relative path, it's important that the URI of the containing resource =
be an absolute path so that relative location can be interpreted =
properly. In that case "*.xsd" would not be so good and you might want =
to take the name of the actual location of the bigger file (modelURL) =
and append .xsd to it to create your "fake" XSD URI.

I also made a comment line below about the add of the resource being =
unnecessary since the createResource will already have added it...

Ed,

Thanks for the quick response. For my purposes the solution is =
relatively
easy now that I know I'm not missing something easy in the original
approach. I did run across something that didn't work as I thought it
should from reading the XSD FAQ.

I think I should be able to do this to get empty resources that I can =
load.
// initalize packages
XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();
// set up resource registry

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test=
",n
ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd"=

w XSDResourceFactoryImpl());
// get "empty" resources
ResourceSet resourceSet =3D new ResourceSetImpl();
TestResourceImpl testResource =3D
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
XSDResourceImpl xsdResource =3D
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));

In both cases resourceSet.createResource() returns null, and I'm not =
sure
why. I traced into it and it looks as if the resource factory registry
hasn't been initialized yet.

John

The "solution" to the original problem follows. Please let me know if
anyone sees problems with it (exception handling obviously needs to be
added).

String modelURL =3D args[0];
DocumentBuilderFactory factory =3D =
DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder =3D factory.newDocumentBuilder();
Document document =3D builder.parse(new FileInputStream(modelURL));

ByteArrayOutputStream baos =3D new ByteArrayOutputStream();

TransformerFactory.newInstance().newTransformer();

XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test=

ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd"=

ResourceSet resourceSet =3D new ResourceSetImpl();
// TestResourceImpl testResource =3D
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
// XSDResourceImpl xsdResource =3D
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));
TestResourceImpl testResource =3D new
TestResourceImpl(URI.createURI("*.test"));
XSDResourceImpl xsdResource =3D new
XSDResourceImpl(URI.createURI("*.xsd"));
resourceSet.getResources().add(testResource);
resourceSet.getResources().add(xsdResource);
The created resource is already added, so this is a no-op.

// get the embedded schema, load it into an XSDSchema instance, and =
add
it to the xsd resource
Element schemaElement =3D
(Element)document.getDocumentElement().getElementsByTagNameN S( "http://www=

John,

I was anticipating this problem which is why I added my comment about
making sure that the URI of the XSDResourceImpl is the correct absolute
URI against which relative locations should be resolved. Are you using
modelURL + ".xsd" as the URI now? The URI needs to be absolute, i.e,.
http://..., file:/, platform:/, and so on...

In that case "*.xsd" would not be so good and you might want to take the name of the actual location of the bigger file (modelURL) and append .xsd to it to create your "fake" XSD URI.

<pre wrap="">Ed,

Thanks for the quick response. For my purposes the solution is relatively
easy now that I know I'm not missing something easy in the original
approach. I did run across something that didn't work as I thought it
should from reading the XSD FAQ.

I think I should be able to do this to get empty resources that I can load.
// initalize packages
XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();
// set up resource registry

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test",n
ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd",ne
w XSDResourceFactoryImpl());
// get "empty" resources
ResourceSet resourceSet = new ResourceSetImpl();
TestResourceImpl testResource =
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
XSDResourceImpl xsdResource =
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));

In both cases resourceSet.createResource() returns null, and I'm not sure
why. I traced into it and it looks as if the resource factory registry
hasn't been initialized yet.

John

The "solution" to the original problem follows. Please let me know if
anyone sees problems with it (exception handling obviously needs to be
added).

String modelURL = args[0];
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new FileInputStream(modelURL));

ByteArrayOutputStream baos = new ByteArrayOutputStream();
Transformer transformer =
TransformerFactory.newInstance().newTransformer();

XSDPackage.eINSTANCE.getEFactoryInstance();
TestPackage.eINSTANCE.getEFactoryInstance();

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.test",n
ew TestResourceFactoryImpl());

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "*.xsd",ne
w XSDResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
// TestResourceImpl testResource =
(TestResourceImpl)resourceSet.createResource(URI.createURI("*.test "));
// XSDResourceImpl xsdResource =
(XSDResourceImpl)resourceSet.createResource(URI.createURI("*.xsd "));
TestResourceImpl testResource = new
TestResourceImpl(URI.createURI("*.test"));
XSDResourceImpl xsdResource = new
XSDResourceImpl(URI.createURI("*.xsd"));
resourceSet.getResources().add(testResource);
resourceSet.getResources().add(xsdResource);

<pre wrap="">John,

This is much easier said than done. A schema model instance must be
constructed from a DOM, so you need to create a DOM when parsing and
then use that to create the XSDSchema. Similarly, when serializing, you
need to get the DOM from the XSDSchema and serialize that. The folks
doing a WSDL model need to solve this problem, but that's been done by
making the WSDL model work much like the XSD model. Probably is you
look at how XSDResourceImpl implements doSave and doLoad, it will be
more clear how it works (and that you have a hard problem to solve.).
