通过“ {}”解析字符串

Question

The format of the output is [{uuid, Readings}, {uuid, Readings}, {uuid,Readings}]
(Usually longer than this)

For example ... (All one string, just formatted to be easier on the eyes).

[{"uuid": "e2e38e4e-431d-508a-a5f9-e50eaffe6aab", "Readings": [[1351329301000.0, 0.0], [1351330202000.0, 0.0], [1351331102000.0, 0.0]]}, 

{"uuid": "8ed157d9-b31d-5075-bad6-69dfde7a34a4", "Readings": [[1351329301000.0, 0.0], [1351330202000.0, 0.0], [1351411200000.0, 494.0]]}, 

{"uuid": "8737f287-14df-5ccd-82df-e66ca7374b63", "Readings": [[1351329300000.0, 515.0], [1351330200000.0, 467.0], ]}]

I want to parse this so that I get everything in between the '{ }' symbols including the '{ }' symbols.

I don't want to separate anything else. Everything in between '{ }' symbols should stay together as one string.

Something that I'm also interested in is adding '[ ]' around each result at the end.

Simple example:

[ {"uuid": 1, "Readings": [[2,3], [2,6]]}, {"uuid": 1, "Readings": [[5,6], [7,7]]} ]

would result in an array where

element 0 = "[{"uuid": 1, "Readings": [[2,3], [2,6]]}]"
element 1 = "[{"uuid": 1, "Readings": [[5,6], [7,7]]}]"

Anyone know the regex expression to select something like this? (I'm using ruby on rails btw)

Answer 1

This is fairly "hacky", but I'd suggest parsing it using a JSON Parser (you'll have to see how exactly to do that yourself, I'm sure there's a library or something). Then, you can stringify each object in the returned array and put them in an array of strings.

Here's how I'd do it in javascript (you can adapt the workflow to RoR)

objArray = JSON.parse(jsonString);
stringArray=[];
for (i=0; i<objArray.length; i++) {
    stringArray.push("[" + JSON.stringify(objArray[i]) + "]");
}

EDIT WHY you want to do it so baffles me, because having the objects in an array would be sooo much more useful
