I'm doing something similar. In my case, it's editing files of different 
formats in a common Editor. Here is my code to get the IDocument:

input = new FileEditorInput(file);
provider = DocumentProviderRegistry.getDefault().getDocumentProvider(input);

provider.connect(input);
document = provider.getDocument(input);

Since I'm editing structured data, my Editor has an IPartListener that 
checks whether the Editor gains/looses focus and (de)serializes the text 
data into the model data.

This enables users to work with the custom editor and a text editor at 
the same time. They shouldn't break the well-formedness of the text data 
though.

The only feature this solution doesn't give you is detecting when the 
file changed on disk. For that, I have no solution. But if anyone else 
has any idea about that, I'm all ears.

PS: Never ever forget to call provider.disconnect() exactly once for 
every provider.connect(), or you'll get the weirdest behaviour!
