Hi,
not sure what it is you are trying to do... but:
- You can naturally always find the text of what is in any open editor.
Either as text, or the parsed model.
- If you want to parse a file, or a string you do that simply by opening
it as an EMF resource (as the text->parser->model transformation is
registered by file extension).

So... if you want the text of the editor - the Eclipse framework will
give you handles to the editor, from which you get its input, a document
etc. and from those you can either open the same file (looking at the
URI in the input), or get the actual XtextDocument, then get the
XtextResource.

Is the functionality invoked from a menu, button or is it triggered by
something else? Could you explain the use case a bit more? I find that
one almost never have to get the actual text in some complicated way...
(so hence my questions).

Regards
