Customization of XML serialization [message #419038] Thu, 08 May 2008 20:13 Go to next message

Hi,

I developped a model with EMF and I want to serialize it with a custom
XML output format.

Here is a brief overview of the contents of my package

MyPackage
TestFile EClass
children EReference 0..*
... with EAttributes
Variable EClass
value EAttribute
name EAttribute
... with other Eattributes
Test Eclass
... with EAttributes
Step Eclass
... with EAttributes
Other Eclasses


I modified the default options of the xml serializatoin and got the
following output:


//---------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<TestFile xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<children xsi:type="Variable" value="myValue1">
<name>myVariableName1</name>
</children>
<children xsi:type="Step">
<children xsi:type="Variable" value="myValue2">
<name>myVariableName1</name>
</children>
</children>
</TestFile>
//---------------------------------------


The current modified XML options are:
ext.setQualified(SeqeditorPackage.eINSTANCE, false);
options.put(XMLResource.OPTION_EXTENDED_META_DATA, ext);
options.put(XMLResource.OPTION_KEEP_DEFAULT_CONTENT, true);


Here are some customization questions:

1- Is is possible to remove all "xsi:" string from the type attributes?

type="Variable" instead of xsi:type="Variable"

2- Is is possible to add a root element <tm> that will include all xml
tag (including the TestFile element)?

3- Is is possible to remove all "xmi", "xmlns:xmi" and "xmlns:xsi"
attribute of the TestFile element?
If necessary these attributes can be set on the <tm> root element. (But
not in the TestFile.

4- Is is possible to output the value of the "value" attribute of the
class variable directly in the body of the xml output instead of adding
a attribute to the xml "variable" tag element.

<child type="variable">myValue1
<name>myVariableName1</name>
</child>

instead of

<child type="variable" value="myValue1">
<name>myVariableName1</name>
</child>

In fact the "Variable" EClass is very special and I would prefer to use
its name attribute as class Name. It is possible to do this?

<myVariableName1>myValue1</myVariableName1>

Thanks a lot.

Vincent

Vincent,

You'd need to use substitution groups to eliminate xsi:types.

Not and still have it mean the same as xsi:type. It's meta data bout the
type, not just regular data in your model.

If you use an XMLResourceImpl instead of an XMIResourceImpl you can get
rid of the xmi stuff. The xsi will only go away if you use substitution
groups.

You can do with for a complex type with mixed content, but this seems
quite odd to me...

I don't think so.

Thanks Ed, your answers help me.

Here is another question:

1- When I set the option "setQualified" of my Package to false, the
loading process throw an assertion. Note, that the file was save with
the same options.

Here are my routines to load and save my model. It come from the
generated editor of my model where I only insert the code that adds the
ExtentedMetaData. (It's possible that the code below is not running, I
removed some lines for the purpose of the question...)

If I set the setQualified to true, it works well.

I also attach the assertion message.

Thanks a lot

Vincent



//-------------------------------------------
final Map<Object, Object> saveOptions = new HashMap<Object, Object>();
saveOptions.put(Resource.OPTION_SAVE_ONLY_IF_CHANGED,
Resource.OPTION_SAVE_ONLY_IF_CHANGED_MEMORY_BUFFER);

// Save the resources to the file system.
boolean first = true;
for (Resource resource : editingDomain.getResourceSet().getResources()) {
if ((first || !resource.getContents().isEmpty() ||
isPersisted(resource)) && !editingDomain.isReadOnly(resource)) {

savedResources.add(resource);

final ExtendedMetaData ext = new BasicExtendedMetaData(
ExtendedMetaData.ANNOTATION_URI,
EPackage.Registry.INSTANCE, new HashMap());
ext.setQualified(SeqeditorPackage.eINSTANCE, false);
saveOptions.put(XMLResource.OPTION_EXTENDED_META_DATA, ext);

resource.save(saveOptions);
first = false;
}
}


//-------------------------------------------
URI resourceURI = EditUIUtil.getURI(getEditorInput());

Resource resource = null;
Map<Object, Object> loadOptions =

ExtendedMetaData.ANNOTATION_URI,

It would be good to see the file.

So the code is maybe meaningless?

This case I would expect to see a namespace in the serialization.
Otherwise, I'd expect the namespace of the root element to be null. If
you try this case by using a schema with a null namespace, you'll see
all the code that's generate for this case.

So I would imagine your intent is for your saved instance will have a
null namespace? Is that the actual result? I'd suggest trying this
scenario with a null target namespace schema an looking closely at the
generate resource factory...

I'll bet there is a cause to this exception which you've not shown...

I hope not :-), but here is the complete code of the createModel method
of the generated editor with some "adds". Is the way I get the
LoadOptions from the resourceSet correct? I think my problem come from
there...

public void createModel() {
URI resourceURI = EditUIUtil.getURI(getEditorInput());
Exception exception = null;
Resource resource = null;
try {
// Load the resource through the editing domain.
//
Map<Object, Object> options =
editingDomain.getResourceSet().getLoadOptions();

final ExtendedMetaData ext = new BasicExtendedMetaData(
ExtendedMetaData.ANNOTATION_URI,
EPackage.Registry.INSTANCE, new HashMap());

ext.setQualified(SeqeditorPackage.eINSTANCE, false);

// Transform xml attribute to xml element
ext.setFeatureKind(SeqeditorPackage.Literals.TM_OBJECT__NAME ,
ExtendedMetaData.ELEMENT_FEATURE);
...
options.put(XMLResource.OPTION_EXTENDED_META_DATA, ext);
options.put(XMLResource.OPTION_KEEP_DEFAULT_CONTENT, true);

resource = editingDomain.getResourceSet().getResource(resourceURI,
true);
}
catch (Exception e) {
exception = e;
resource = editingDomain.getResourceSet().getResource(resourceURI,
false);
}
Diagnostic diagnostic = analyzeResourceProblems(resource, exception);
if (diagnostic.getSeverity() != Diagnostic.OK) {
resourceToDiagnosticMap.put(resource,
analyzeResourceProblems(resource, exception));
}
editingDomain.getResourceSet().eAdapters().add(problemIndica tionAdapter);
}

Yes, the namespace appears when I set the option to true.

Yes, when I set the NS Prefix to an empty string (and setQualified to
true), the save's output looks like what I want. But the setFeatureKind
function of the load options doesn't seem to work anymore. (I got error
like : FeatureNotFoundException: Feature 'name' not found). So,
everything tell me that the load options aren't set correctly...

It seems to work, but all other load options are still ignore as I
mentionned above.

So changing the NS prefix of the ecore file is the correct place to set
the target namespace to null?

You really shouldn't be changing the generated instance itself. These
annotations should be on the model before you generated it. If you'd
ensured the annotations where there on the model the generated uses, it
would have generated a resource factory implementation that works properly.

The options are generally best by the resource factory when the resource
is created, not like this.

Once you've tried these annotations on the actual model being generated,
have a look at the generated resource factory and be sure it's getting used.

The prefix and the namespace are separate concepts. A null target
namespace schema can't have a prefix. A schema with a target namespace
generally should have a prefix except when there are no unqualified
local element declarations.

I would suggest making a very simple schema without a target namespace
and using that to generate an EMF model project and long with the test
project to see it in action. That will illustrate, via the options set
up in the resource factory impl, the options you'll need. The resulting
..ecore file will show you what annotations you should put on your Ecore
model to get the results you want. If you do it properly, the generated
results should work out of the box...
