This function parses its first parameter (a string) as JSON, and returns the resulting sequence of objects and arrays.
parse-json($arg as string?) as json-item*
parse-json($arg as string?, $options as object) as json-item*
The object optionally supplied as the second parameter may contain additional options:
jsoniq-multiple-top-level-items (boolean): indicates whether parsing to zero, or several objects is allowed.
An error is raised if this value is false and there is not exactly one object that was parsed.
If parsing is not successful, an error is raised. Parsing is considered in particular to be non-successful if the boolean associated with "jsoniq-multiple-top-level-items" in the additional parameters is false and there is extra content after parsing a single abject or array.
Example 184. Parsing a JSON document
parse-json("{ \"foo\" : \"bar\" }", { "jsoniq-multiple-top-level-items" : false })
Result (run with Zorba): { "foo" : "bar" }
Example 185. Parsing multiple, whitespace-separated JSON documents
parse-json("{ \"foo\" : \"bar\" } { \"bar\" : \"foo\" }")
Result (run with Zorba): { "foo" : "bar" } { "bar" : "foo" }
