Parse object with numeric key

Hi, can anyone suggest me a way to parse an object like this? I’m only interested in a unique list of the values of “text” property - thats in the last level.

{
“statusCode”: 200,
“body”: {
“0”: {
“disease_model”: [],
“medication_model”: [],
“BioNLP_model”: [],
“general_entities”: [
{
“text”: “60 year old”,
“ent”: “DATE”,
“start”: 1,
“end”: 3
}
],
“text”: “A 60 year old male patient with ?”
},
“1”: {
“disease_model”: [
{
“text”: “UTI”,
“ent”: “problem”,
“start”: 0,
“end”: 0
},
{
“text”: “CHRONIC CYSTITIS”,
“ent”: “problem”,
“start”: 2,
“end”: 3
}
],
“medication_model”: [],
“BioNLP_model”: [],
“general_entities”: [
{
“text”: “CHRONIC CYSTITIS”,
“ent”: “PERSON”,
“start”: 2,
“end”: 3
}
],
“text”: “UTI,CHRONIC CYSTITIS,?”
},
“2”: {
“disease_model”: [
{
“text”: “Hypokalemia”,
“ent”: “problem”,
“start”: 4,
“end”: 4
}
],
“medication_model”: [],
“BioNLP_model”: [],
“general_entities”: [
{
“text”: “ON CKD”,
“ent”: “ORG”,
“start”: 1,
“end”: 2
},
{
“text”: “Hypokalemia”,
“ent”: “ORG”,
“start”: 4,
“end”: 4
}
],
“text”: “AKI ON CKD,Hypokalemia secondary to ?”
},
“3”: {
“disease_model”: [],
“medication_model”: [
{
“text”: “insulin”,
“ent”: “MEDICATION”,
“start”: 0,
“end”: 0
}
],
“BioNLP_model”: [],
“general_entities”: [],
“text”: “insulin use.”
}
}
}
