reading name of json using groovy

Question

I have the below JSON structure and I am trying to retrieve the name order/sale/Cancel to a string variable in groovy

{"Transaction" : {"Order" : { ......
{"Transaction" : {"Sale" : { ......
{"Transaction" : {"Cancel" : { ......

I was able to get to this point, reading the JSON using JSON slurper with some research but not sure how to get read the name.. most of the articles I have seen the point to reading the values and not the name.

final BufferedReader inReader = new BufferedReader(new InputStreamReader(inputStream, 'UTF-8'))
Object result = jsonSlurper.parse(inReader)

I have converted from XML to JSON so if this can be done using either XML or JSON would help.

Correct would be to use :

def json = '{"Transaction" : {"Order" : "result"} }'

def slurper = new groovy.json.JsonSlurper()
def result = slurper.parseText(json)

assert 'Order' == result.Transaction.keySet().first()

If you have JSON in String you don't need to create BufferedReader, just use parseText. After you parse JSON you can just access it by traversing properties.

def slurper = new groovy.json.JsonSlurper()
def result = slurper.parseText(inputStream.text);

result.Transaction.Order //result

json is not in string, so have to use the bufferedReader – anuj Jul 28 '16 at 14:50
You can use `getText()` method on inputStream to get it as String. Edited my answer. – Krzysztof Atłasik Jul 28 '16 at 15:03
