Hi All, hopefully someone may have seen this before....

I have created an ecore and genmodel from an XSD which is all fine however when I create a model and try to save it using the generated resource factory along with the (XMLResource.OPTION_FORMATTED, Boolean.TRUE) option I am getting a single line of text in the file...

Any thoughts anyone?? What am I doing wrong??

Jon,

You've not said much about your model, but if the XSD involves complex
types with mixed content, EMF will print out exactly the white space
that appears in the feature maps corresponding to that mixed content.
Serializing will not alter the model itself to introduce formatting. In
other words, the formatting option only applies for instances of
EClasses for which
org.eclipse.emf.ecore.util.ExtendedMetaData.getContentKind(EClass) is
UNSPECIFIED_CONTENT or ELEMENT_ONLY_CONTENT, i.e., only for the cases
where just white space is allowed and that white space is not meaningful
nor recorded in the model upon deserialization.

Hey Ed,

Thanks for you reply... your right, looking at the ecore model the content kind is of type mixed so that may explain why this happening.. I realize at the end of the day nicely formatted code makes no difference to the ability for EMF to load or save the data but I would like it to be formatted nicely as the users will want to look at the files I produce so I guess my options now are to get EMF to serialize the model for me and to then look at something like the javax Transformer factory to pretty print the string before writing it to a file....

Jon,

I'm curious if these places that are marked mixed in the schema really
are intended to capture non-whitespace information that's somehow
meaningful and relevant to the end-user of this XML?

Hey Ed, I am using a model generated from Spring's Beans and Integration schemas, I haven't altered the generated ecore or genmodel in anyway nor do I fully understand that intracies of the schema and resulting ecore model... I just had a look at the model after your first reply to see what the metadata kind value was set to which as you said may be set to mixed which it is...

Apologies for slightly changing the subject here but I am also seeing in the serialization that EMF is including elements that are empty! is there anyway to tell EMF to omit empty elements in the resulting serialization??

Fortunately it's all automatic. :-P

If you annotated the schema (ecore:mixed="false", you could turn mixed
off, but then non-whitespace mixed content would be ignored.

I'd need more details. Perhaps you've set some feature's value to the
empty string?

It won't serialize a feature if eIsSet is false, so this suggest you've
set something to the empty string.
