Trying to get that Karma up, huh? I'll bite and help you out a bit. I would think the only reason to use XML in a new project would be because it has a schema and you may need your objects "strongly typed." In days past there also wasn't very good support for JSON in C# and other enterprise languages so that extended the XML lifetime. Most times you're using XML now it's to integrate with a piece of legacy software. Now that most enterprise platforms have good support for JSON, outside of a few special use cases most projects are just going to go with JSON for the convenience of it (no crazy parsers to deal with).
