Parsing JSON vs. Parsing XML in an IOS project

Question

In the backend of my IOS project, the admin is saving the data into a DB or in an XML file. So whenever he wants, he can simply add an entry.

In the IOS app, I want to retrieve the data.

If I use XML, I can directly parse the XML file, since data are already in XML format (when admin added the value, the XML file got updated).

If I use JSON, I have to connect to the DB, get the result of the query and then encode it into JSON.

So, what do you think would be faster, in terms of the response come into phone.

Is there any other option that I didn't take into account?

I have read all of these similar questions:

and many more, but I want to ask something specific for my project.
