Parsing JSON using jq or Python - json

Question

I have this nested JSON
[
"[[Input=[Name=ABC, createDateTime=2019-30-11, RollNumber=9]]]",
"[[SubjectList=[Summer=, Winter=, Autumn=, Spring=, rList=, sList=, additionalList=, emailList=, FoodList=, sAssignmentList=, summerworkList=, outdoorList=, movielist=]]]",
"[ProcessingDate=2018-10-06]",
"[Hobbies=Football]",
"[Phone=Android,,]"
]
How can I process this JSON and get the value football or rollnumber using Python?
This is what I tried:
Code
import json
row = '''[
"[[Input=[Name=ABC, createDateTime=2019-30-11, RollNumber=9]]]",
"[[SubjectList=[Summer=, Winter=, Autumn=, Spring=, rList=, sList=, additionalList=, emailList=, FoodList=, sAssignmentList=, summerworkList=, outdoorList=, movielist=]]]",
"[ProcessingDate=2018-10-06]",
"[Hobbies=Football]",
"[Phone=Android,,]"
]'''
row_dict = json.loads(row)
print(row_dict[3])
Using this - I get following output:
[Hobbies=Football]
But I am missing next level parsing to get just football as output

Answer 1

Here is an approach that uses capture on the non-json strings in the array.
It assumes the [:alnum:] posix regex character class suffices to match the values after the =
Sample execution assuming data in test.json
$ jq -M '.[] | capture("Hobbies=(?<Hobbies>[[:alnum:]]+)")' test.json
{
"Hobbies": "Football"
}
Here is a variation which produces exactly Football:
$ jq -Mr '.[] | capture("Hobbies=(?<Hobbies>[[:alnum:]]+)") | .Hobbies' test.json
Football
Here's an example script which uses multiple captures and combines them with add
[ .[]
| capture("Hobbies=(?<Hobbies>[[:alnum:]]+)")
, capture("RollNumber=(?<RollNumber>[[:alnum:]]+)")
] | add
Sample execution assuming script in test.jq
$ jq -M -f test.jq test.json
{
"RollNumber": "9",
"Hobbies": "Football"
}
