Hi
As requested here is an example file with some redacted data:
ZA105:{"Aircraft Type":"Sea King", "Lifed Items":{ "port engine
ser#":"RR-P1234", "starboard engine ser#":"RR-S1234","gearboxes ser#":[
"WHM1234", "WHI1234", "WHT1234" ] }}
ZA106:{"Aircraft Type":"Sea King", "Lifed Items":{ "port engine
ser#":"RR-P2345", "starboard engine ser#":"RR-S2345","gearboxes ser#":[
"WHM2345", "WHI2345", "WHT2345" ] }}
ZA107:{"Aircraft Type":"Merlin", "Lifed Items":{ "port engine ser#":"RR-P3456",
"starboard engine ser#":"RR-S3456","centre engine ser#":"RR-C3456","gearboxes
ser#":[ "WHM3456", "WHI3456", "WHT3456" ] }}
ZA108:{"Aircraft Type":"Merlin", "Lifed Items":{ "port engine ser#":"RR-P4567",
"starboard engine ser#":"RR-S4567","centre engine ser#":"RR-C4567","gearboxes
ser#":[ "WHM4567", "WHI4567", "WHT4567" ] }}
ZA109:{"Aircraft Type":"Wessex", "Lifed Items":{ "port engine":"RR-P9876",
"starboard engine":"RR-S9876","gearboxes":[ "WHM9876", "WHI9876", "WHT9876" ] }}
ZA104:{"Aircraft Type":"Wessex", "Lifed Items":{ "port engine":"RR-P8765",
"starboard engine":"RR-S8765","gearboxes":[ "WHM8765", "WHI8765", "WHT8765" ] }}
ZA103:{"Aircraft Type":"Wessex", "Lifed Items":{ "port engine":"RR-P7654",
"starboard engine":"RR-S7654","gearboxes":[ "WHM7654", "WHI7654", "WHT7654" ] }}
What I would like is the aircraft tail no eg ZA104 to be the key of the cache
item and everything after the colon (the aircraft type and replaceables serial
numbers to be the cached item value. The cached item value can stay as a JSON
string.
Many thanks
Dave

Dave,
Can you post a redacted example with dummy
data?
Thanks,
