Hi,
I am wondering if I would be able to ignore a set of certain features
while loading an EMF resource.
Basically, I have two products.
1. Product B --> contains Product A. (These are actually eclipse
features but I want to avoid confusion with emf features.)
2. Product B has b.xsd and Product A has A.xsd such that B.xsd imports
A.xsd.
3. Product A has A model, Product B has B model.
If I create an EMF XML resource with elements from B as well as A, and
send it to A model, I would like to process only A specific EMF features
while ignoring B specific EMF features. With current settings, it's
going to fail since A product ALONE does not contain B model.
XML will look like following:
<B:x>
<B:y/>
</B:x>
<A:m>
<A:n/>
</A:m>
How do I accomplish this?
Thanks,
Vasant.

Vasant,
Probably XMLResource.OPTION_RECORD_UNKNOWN_FEATURE will help. With this
approach, its possible to write back out the original unrecognized data,
or to clear the getEObjectToExtensionMap to discard it.

Hi Ed,
Thanks, for the quick reply. That solves most of my problem.
One follow up question:
As I was writing the earlier post, I realized if it could also be
possible to distinguish between the intended set of features to ignore
and true errors like <A:m11> instead of <A:m> or misspelled attributes
of such elements.
Thanks,
Vasant.

Vasant,
It's possible to post process the information in the
getEObjectToExtensionMap() to see what attributes and elements were
present and then to decide which ones represent errors as opposed to
expected problems.
