Question :
- Given a Json Object in the form of Map<String, Object>, and given a query to match a key by path (similar to jq), extract its value.
- How can you extend the functionality to support any key (“*”) match?
Note: No json parsing required.
Examples:
dict = '{"fname": "masked_first_name", "lname": "masked_last_name", "contacts": {"cell": "+1(999).999.9999", "home": "+1(333).333.3333" }}'
key = ".contacts.cell"
res = “+1(999).999.9999”
dict = '{"fname": "masked_first_name", "lname": "masked_last_name", "contacts": {"cell": "+1(999).999.9999", "home": "+1(333).333.3333" }}'
key = ".fname"
res = “masked_first_name”
dict = '{"fname": "masked_first_name", "lname": "masked_last_name", "contacts”:{“home”:”12345”}}’
key = ".contacts.cell"
res = null
dict '{"fname": "jomasked_first_namehn", "lname": "masked_last_name", "contacts": {"cell": "+1(999).999.9999", "home": "+1(333).333.3333" }}'
key = ".*.cell"
res = ["+1(999).999.9999"]
dict = '{"fname": "jomasked_first_namehn", "lname": {"cell": "+1(888).999.9999", "home": "+1(555).333.3333" }, "contacts": {"cell": "+1(999).999.9999", "home": "+1(333).333.3333" }}'
key = ".*.cell"
res = ["+1(888).999.9999", "+1(999).999.9999"]
key = contact.*
res = {'cell': '+1(999).999.9999', 'home': '+1(333).333.3333', 'cells': {'cell1': '121211'}}
