Class JsonData

java.lang.Object

org.mule.module.json.JsonData

public class JsonData
extends Object

A wrapper for the JsonNode object that allows for nested object keys i.e. user/name will return the name property on the user object.

There is no 'xpath' for JSON yet (though I expect Jackson to do implement this at some point). This class provides a simple way to navigate a Json data structure. To select a child entry use - person/name

to access array data, use square braces with an index value i.e. person/addresses[0]/postcode

or

[0]/arrayElement

Also, multi-dimensional arrays can be accessed using: filters[1]/init[1][0]

if a Json property name contains a '/' the name needs to be quoted with single quotes i.e.

results/'http://foo.com'/value
