[jQuery] OT: XML vs JSON

I really like json, and the ability to recognize arrays is great.
However, there is strength of xml in that order can be preserved. I
can not think of a way to implement this in json. Is it possible and I
am simply blind to the truth?
XML:

TitleSubtitleAuthor

JSON:
{"p":{"b":["Title","Author"],"i":"Subtitle"}}
