REST API imports

Hi All

I import host and service informations from Atlassian Insight REST API.
It works mostly but I’ve a Problem with such a construct:

{
10.0.0.0/24: {
displayValue: “10.0.0.0/24”,
bla: “bup”
}
192.168.10.0/24: {
displayValue: “192.168.10.0/24”,
bla: “foo”
}
}

I want with use of modifiers get the values of the key displayValue nad bla into 2 custom vars as arrays or strings
Example:
host_subnet = 10.0.0.0/24, 192.168.10.0/24
host_subnet_desc = bup, foo

What modifier can I use and how?
