Hi,
I'm deleting an Element from an Abstract schema.
Assuming that XSDElementDeclaration "element" is not global, ie: it is
declared inside some other declaration I believe all I do is remove
the particle from the model group list:
XSDElementDeclaration element;
// Get the particle for this element
XSDParticle particle = (XSDComponent)element.getContainer();
// Get model group containing the particle
XSDModelGroup group = (XSDModelGroup)particle.getContainer();
// Remove the particle
group.getContents().remove(p);
I hope I got this one right. It seems to work okay but I'm worried I have
oversimplified this and forgotten something really important. Any comments?
Thanks

Wow! Just EcoreUtil.remove(object)? That would be very cool.
In my case I have a schema loaded into a simple tree model. I keep a
reference to the schema EObject that each tree node corresponds to:
Schema: reference to XSDSchema
Elements: reference to XSDElementDeclaration (resolved)
Attributes: reference to XSDAttributeUse
Model Groups: reference to XSDModelGroup
I just do an "instanceof" to know what kind of node I'm looking at and
display the proper icon.
Does this mean I could use EcoreUtil.remove(object) to delete each of these
from the XSD model?
XSDElementDeclaration element
EcoreUtil.remove(element);
I thought that the Particle containing the Element might get left behind.
Thanks

Gary,
EcoreUtil.remove simply breaks the parent link. It will leave the
particle or attribute use behind.
