I have created a grammar using xtext, and generated the DSL. Now, I want to transform the DSL elements (program that is conforming to the grammar) to XML elements. So, I am wondering if there is a framework that allows to do that using Java for example. I could open the files having the extension of the DSL using the eclipse editor "Sample Reflective Ecore Model Editor" and could visualize the elements of the DSL.
I couldn't get the XMI representation of the file.
Is there any solution to perform the transformation?
Thank you in advance.

Hi
In principle, Xtext is just an alternative textual syntax for an EMF resource, so interactively Save as YourFile.xml should work, and I think it used to, but no more. (If Xtext is going to ignore the extension on a regular Save AS, it would be nice if there was a distinct Save AS XML action.)
Programmatically, Xtext loads and parses your model to a Resource conforming to YourDSL.ecore, so programatically after you have loaded/parsed YourDSLResource, you can create a new (XML)Resource, assign the top level YourDSLResource.getContents() to (XML)Resource and save it. If you want to continue using Xext facilities, assign the contents back again.
