Dear Wray,
I tried to come up with a sketch of what–I think–might help you:
https://gist.github.com/micheee/8a8734a1713a7121cab15eb3dfb389d9
Basically it boils down to:
1. Fetch the JSON
2. Convert that JSON to an XQuery item
3. Iterate over each array entry and explicitly construct the XML
representation you want
So in a nutshell, in XQuery 3.1, something like the following:
>
> fetch:text('https://gist.githubusercontent.com/Miserlou/c5cd8364bf9b2420bb29/raw/2bf258763cdddd704f8ffd3ea9a3e81d25e2c6f6/cities.json')
> => parse-json() (: Convert to XQuery item representation :)
> => array:for-each(function($map){ (: For each entry in that array, do :)
> element item { (: Construct an XML element named item :)
> $map => map:keys()
> => for-each(function($key){ (: For each key in the map, do: :)
> element { $key } { (: Return an element named $key :)
> $map($key) (: …and the value of $map($key) :)
> }
> })
> }
> })
> => array:flatten() (: Converts the array to a sequence :)
I assume you are using BaseX, so maybe the json:parse() function might be
another option, that is based on our own implementation and will create an XML
representation right away:

> => json:parse()
For more info on our BaseX JSON-Module see:
http://docs.basex.org/wiki/JSON_Module
As I can only guess what your XQuery code actually looks like I hope this comes
somewhat close to what you want.
Hope this helps ;-)
