I have JSON input from which I want to pull out the same sub-elements of arrays into one field. Trying to figure how to structure JSLT using NiFi JSLTTransformJSON processor.
Input:
{
"name": "John Smith",
"ID": "123123123",
"address": [
{
"location": "123 Main, Citty, ST",
"info": {
"type": "single family",
"own": "yes"
}
},
{
"location": "123 Lane, Wonderland, ST",
"info": {
"type": "apartment",
"own": "yes"
}
},
{
"location": "123 Street, Place, ST",
"info": {
"type": "condo",
"own": "no"
}
}
]
}
Desired output:
{
"name": "John Smith",
"ID": "123123123",
"residence_type": "single family, apartment, condo"
}
Desired output where the info.own == "yes" :
{
"name": "John Smith",
"ID": "123123123",
"residence_type": "123 Main, Citty, ST; 123 Lane, Wonderland, ST"
}
where I don't know how many addresses there might be.
For the first desired output:
{
"residence_type":join([for (.address) .info.type],", "),
"address":null,
*:.
}
For the second desired output:
{
"residence_type":join([for (.address) .location if(.info.own=="yes")],", "),
"address":null,
*:.
}
If you are trying to combine both based on the info.own value:
{
"residence_type":join([for (.address) .location if(.info.own=="yes")]+[for (.address) .info.type if(.info.own!="yes")] ,"; "),
"address":null,
*:.
}
if you are getting the info.own as flowfile attribute you can include in the JSLT spec using Expression Language and use jslt function to drive the output:
def residence_type(info_own)
if($info_own=="yes")
join([for (.address) .location if(.info.own=="yes")],"; ")
else
join([for (.address) .info.type],", ")
{
"residence_type":residence_type("${info.own}"),
"address":null,
*:.
}
Hope that helps.
