XML is a fine format in comparison to JSON.
I hate writing and reading xml compared to json, I don't really care if one is slightly leaner than the other. If your concern is the size or speed you should probably be rethinking how you serialize the data anyway (orotobuff/DB)
XML has its strengths as a markdown format. My own formatted text format ETML is based on XML, as I could recycle old HTML conventions (still has stylesheet as an option), and I can store multiple text blocks in an XML file. It's not something my main choice of human readable format SDL excels at, which itself has its own issues (I'm writing my own extensions/refinements for it by the name XDL, with hexadecimal numbers, ISO dates, etc.).
