Hello everyone,
I began to work on an EMF project just few days ago, and I encounter some problems.

Here is my situation: I have a simple input file example.model conforms to a MetaModel:

<?xml version="1.0" encoding="ASCII"?>
<CollegeMMDiff:DifferenceModel xmi:version="2.0" xmlns:xmi=".../XMI" xmlns:xsi=".../XMLSchema-instance" xmlns:CollegeMMDiff=".../org.openembedd.CollegeMMDiff" xmi:id="_nBd54IemEeCwk8SZVLPN7A">
  <differenceElements xsi:type="CollegeMMDiff:ChangedCollege" xmi:id="_ojXxgIemEeCwk8SZVLPN7A">
    <classrooms xsi:type="CollegeMMDiff:ChangedClassRoom" xmi:id="_q5IH8IemEeCwk8SZVLPN7A" location="U2-036" updatedElement="_r04lkIemEeCwk8SZVLPN7A"/>
    <lessons xsi:type="CollegeMMDiff:ChangedLesson" xmi:id="_zE6doIemEeCwk8SZVLPN7A" classroom="_q5IH8IemEeCwk8SZVLPN7A"/>
  </differenceElements>
  <differenceElements xsi:type="CollegeMMDiff:College" xmi:id="_pTDiAIemEeCwk8SZVLPN7A">
    <classrooms xmi:id="_r04lkIemEeCwk8SZVLPN7A" location="U2-039"/>
    <lessons xmi:id="_zwkpwIemEeCwk8SZVLPN7A" students="_yEilwIemEeCwk8SZVLPN7A" classroom="_r04lkIemEeCwk8SZVLPN7A"/>
  </differenceElements>
  <differenceElements xsi:type="CollegeMMDiff:DeletedMatter" xmi:id="_wKWJ8IemEeCwk8SZVLPN7A" title="Math"/>
  <differenceElements xsi:type="CollegeMMDiff:AddedMatter" xmi:id="_xIMSQIemEeCwk8SZVLPN7A" title="Italian"/>
  <differenceElements xsi:type="CollegeMMDiff:AddedStudent" xmi:id="_yEilwIemEeCwk8SZVLPN7A" name="John"/>
</CollegeMMDiff:DifferenceModel>


And I want to display this model in a tree structure (in an Eclipse view previously created).
But I really don't know how to proceed, what I have to use (EMF API?)...

Does someone could enlighten me on this?

Thank you very much!

Hi Ren,

You can always your model in the sample ecore reflective editor which gives you a tree view
of your model.

cheers,
Saurav

Thanks!
Ok, maybe I'm wrong, but the different elements are not ecore elements but elements conforms to a metamodel previously defined, so an ecore parsing can't give me the structure of this .model file, wihtout considering the metamodel, isn't it?

Is someone can tell me how to parse my model with the EMF API?
Thanks!

Hi ?

Interactively, Open With Sample Reflective Ecore Editor.

Programmatically, reuse the TreeViewer code from the Same Ecore Editor.

Renaud,

In all cases, you must have an Ecore model to parse an *.xmi file. It
might just be a dynamic Ecore model you read from a *.ecore file, but
you definitely need to know the model.
