How to Split a JSON array in WSO2 ESB

Say you have this JSON array.

Now you want to split users, and call some backend service for each user. Here is how to do. (Here I'm logging each user details instead of calling a backend service.)

Output will look like this.

[2015-08-18 15:49:27,200]  INFO - LogMediator Name is = X, Age is = 10
[2015-08-18 15:49:27,204]  INFO - LogMediator Name is = Y, Age is = 12
[2015-08-18 15:49:27,205]  INFO - LogMediator Name is = Z, Age is = 15

Hope this will be helpful to someone.
