  <p>Now i have to extract all the id's and name.use, name.given, name.family, name.prefix into corresponding csv files.
  eg: id into id.csv file; name.given into name_given.csv file etc...
  the http request can contain n number of id's and names. How to do that?
  i have tried and failed using json extract and regular expression.</p>
