You should have some understanding of EMF to utilize Xtext, like
modeling with Ecore, loading resources and navigating EObjects.

When Xtext parses a file, you get a DOM consisting of instances of your

Xtext registers a so-called resource factory for a file extension, so
whenever such a file is loaded by EMF's the parser will kick in and
