Hi

I've defined a specific domain model in ecore. The instances of this model are serialized in XMI. I've also dedicated sirius representation for diagram and table edition. Now, I would like to also have a textual edition of these instances and naturally thought to use XText. I've create the xtext grammar and generated the code for this dsl, but I'm facing the problem that I'm not sure how to load my instances serialized in XMI and convert into plain text (valid with the grammer) into the XTextEditor.

My idea idea was to extend

org.eclipse.xtext.ui.editor.XtextEditor

to intercept the moment the xmi file is opened and to convert it into plain text and to convert back from plain text to xmi when the edition with XTextEditor is finished. I'm not sure whether this is a correct way to proceed and how to do it. By how to do it, I mean which functions do I have to extend in

org.eclipse.xtext.ui.editor.XtextEditor

when the file is opened and saved to convert the xmi content. Any reference would be useful.

thank you and kind regards
