Handle comments in xml file on Resource load/save [message #417315]

Hello,

I have a schema based EMF model and i use Resource load and save to
export and import an XML file which is schema complaint.

Problem is, some of the XML files have a lot of information (useful when
just viewing the xml file) in the form of comments.

The comments may carry some versioning information also, however these
comments are not required for me from the code/ model perspective. But,
when I save back the xml file after say, a few changes ... all these XML
comments are gone.

I have tried using the XMLResource.OPTION_USE_LEXICAL_HANDLER, and
OPTION_EXTENDED_META_DATA options but in vain. Am I missing something ?
Any help will be very useful.

cheers,
Chetan Kumar

Hi,

If you want to save these XML comments then I think you will need to set
mixed="true" to the appropriate complexType in your schema. The downside
to this is that your generated code for this type will use FeatureMaps for
its features, instead of the straightforward or more "natural-looking" API
:)

Hth,
Ron

Ron,

It's kind of horrible but the only way right now. It makes me wonder if
an option that populates the comments into this map (the same way as
unrecognized content can be handled) might be useful to a significant
number of clients:

| /**
* Returns the map with {@link EObject} as keys and corresponding {@link org.eclipse.emf.ecore.xml.type.AnyType}s as the values.
* It's used to record unrecognized elements and attributes.
*/
Map<EObject, AnyType> getEObjectToExtensionMap();|
