unlang substring with nas-port-id

[Łukasz Kopiszka]

Hi,

I'm receiving from SE100:
NAS-Port-Id = "2/2 vlan-id 1001 clips 132019"

How to extract number 1001 which will be used in code:

switch "extracted vlan-id" {
        case 1000 {
                ...
    }
        case 1001 {
                ...
    }
        case 1002 {
                ...
    }
...
}
