How can I extract data from JSON?


How can I extract data from JSON?

hope this fix your issue You're trying to get a json object from string array.
Instead of this:
code :
    for(int i = 0; i < jsonArray.length(); i++){
        jsonObject = jsonArray.getJSONObject(i);
        addresses.add(jsonObject.toString());
    }
    for(int i = 0; i < jsonArray.length(); i++){
        String spinnerElement =  jsonArray.getString(i);
        addresses.add(spinnerElement);
    }

I wish this help you Your problem is the use of the "." in the identifier "beans.Person" meaning that you must quote it, like so:
code :
obj.records[0]["beans.Person"][0].id
<div id="result"></div>

var obj = {
    "records": [{
        "beans.Person": [{
            "id": 21,
            "name": "Name21",
            "username": "Username21",
            "password": "password21",
            "age": 41,
            "sex": true
        }, {
            "id": 22,
            "name": "Name22",
            "username": "Username22",
            "password": "password22",
            "age": 42,
            "sex": true
        }, {
            "id": 23,
            "name": "Name23",
            "username": "Username23",
            "password": "password23",
            "age": 43,
            "sex": true
        }, {
            "id": 24,
            "name": "Name24",
            "username": "Username24",

fixed the issue. Will look into that further There is a known bug with the inline response that should be fixed in 8.0-3.
In the interim, it should work to get the extracted fragments either as XML or as a multiplepart/mixed response (which, if the source documents are XML would also be XML).

around this issue The problem is with the %{DATA:jsonLog} part. The DATA pattern, .*?, is not greedy (see here), so it won't grab anything and won't create the jsonLog field. You'll need to use the GREEDYDATA pattern instead.
See http://grokconstructor.appspot.com/do/match#result to test your patterns.

With these it helps I'd just iterate once through the existing list to get the "Bad" keys and then iterate again. I'm sure there's a fancier way, but I don't think it would be any faster or more readable.
code :
data = [
 {'data_1': 1, 'data_2': 1, 'key': 'A'}, 
 {'data_1': 0, 'data_2': 1, 'key': 'B'}, 
 {'data_1': 1, 'data_2': 0, 'key': 'A'}
 ]

bad_data = set([item['key'] for item in data if item['data_1'] == 1])

new_data = []
for item in data:
    item['value'] = 'Bad' if item['key'] in bad_data else 'Good'
    new_data.append(item)
bad_data = set([item['key'] for item in data if item['data_1'] == 1])

for item in data:
    item['value'] = 'Bad' if item['key'] in bad_data else 'Good'
