EMF compare support basic xml? [message #1068453]

Hi, my friends:
I'm working on implement to compare xml files and show the diffrence with UI. I have used text compare with eclipse compare plugin, but it just for compare text. From my research, I found EMF compare suitable for me. I have written a pragram to open EMF compare dialog and show difference for two ecore files, that's done. But if I replaced the ecore files with any other xml files, it doesn't work.
The any other xml files means that, that's ordinary xml at attachment.
My question: Is EMF compare only support emf model files to compare? If it's not, how can I implement for the basic XML files comparation?

Thanks,
Andy.

Andy,

EMF Compare supports any file that can be considered a model and loaded through EMF. Models are not always serialized as XMI files, and we do support other file formats.

That being said, we can also support "plain XML" files if they have a clear xsd expressing the rules to which they conform. You can look at EMF tutorials on how to generate the model corresponding to your xsd. If you do not have an xsd or metamodel for that xml file, then no, you will not be able to use EMF Compare to compare them unless you create said metamodel.

Laurent,
Thanks a lot for your reply.
I have saw "EMF tutorials on how to generate the model corresponding to your xsd", as my option, it tells me how to generate model from schemal files, but I need to generate model from plain XML with schemal defined.

thanks,
Andy.

Hmm, I'm having trouble comparing .emftvm files, which have a custom binary resource factory. The EMF generated editor, as well as the Sample Reflective Ecore Model Editor, work fine for .emftvm files, so I suppose the resource factory is properly registered. What else does EMF Compare require to recognise .emftvm as an EMF model?

Cheers,
Dennis
