Question

pls help me out wit this jolt specification. pls help me
Notes :
Resourcename is the last element of ResourceId which will be a new attribute that we need to add to the expected output
Tags field needs to be copied and splited as mentioned in the expected output.
Input :
[
{
"ResourceId": "/subscriptions/bb842437aa4/resourceGroups/ECHLABHENKEL/providers/Microsoft.Compute/virtualMachines/pmoapps",
"Tags": "Name\": \"PMOapplication\",\"Owner\": \"Breil sathish"
},
{
"ResourceId": "/subscriptions/bb842437aa4/resourceGroups/HCLTECHLABHENKEL/providers/Microsoft.Compute/virtualMachines/pmoapps",
"Tags": "Name\": \"PMOapplication\",\"Owner\": \"Breil sathish1"
}
]
Expected Output :
[
{
"ResourceId": "/subscriptions/bb842437aa4/resourceGroups/ECHLABHENKEL/providers/Microsoft.Compute/virtualMachines/pmoapps",
"Tags": "Name\": \"PMOapplication\",\"Owner\": \"Breil sathish",
"Resourcename": "pmoapps",
"Name": "PMOapplication",
"Owner": "Breil sathish"
},
{
"ResourceId": "/subscriptions/bb842437aa4/resourceGroups/HCLTECHLABHENKEL/providers/Microsoft.Compute/virtualMachines/pmoapps",
"Tags": "Name\": \"PMOapplication\",\"Owner\": \"Breil sathish1",
"Resourcename": "pmoapps",
"Name": "PMOapplication",
"Owner": "Breil sathish1"
}

You can use the following transformation spec as reading the explanations stated at the beginning of each of them such as
[
{ // Convert the value of the attributes to individual arrays with the identical names
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"ResourceName": "=split('/', #(1,ResourceId))",
"tag": "=split(',', #(1,Tags))"
}
}
},
{ // Generate tag0 and tag1 attributes by splitting members of the "tag" array
"operation": "shift",
"spec": {
"*": {
"*": "&1.&",
"tag": {
"*": {
"#": "&3.&2&1"
}
}
}
}
},
{ // Split related strings by colon characters for "tag" array while deriving the last element of "ResourceName" array
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"R*": "=lastElement(#(1,&))",
"tag*": "=split(': ', #(1,&))"
}
}
},
{ // Match components of "tag" array component 1 against component 2
"operation": "shift",
"spec": {
"*": {
"*": "&1.&",
"tag*": {
"#1,&[1]": "&2.&1.#(2,&[0])"
}
}
}
},
{ // Split the values by \" character combination
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"tag*": {
"*": "=split('\"', #(1,&))"
}
}
}
},
{ // Prune undesired values for right-hand-side
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"tag*": {
"*": "=join('', #(1,&))"
}
}
}
},
{ // Prune undesired values for left-hand-side(keys)
"operation": "shift",
"spec": {
"*": {
"*": "[&1].&",
"tag*": {
"\"*\"": "[&2].&(0,1)",
"*\"": "[&2].&(0,1)"
}
}
}
}
]
