Hi all  
I have a field like this

```auto
field: 10, 20, 30, 40

```

now that i want to make each of the data in the field to be parse like this:

```auto
field.1: 10
field.2: 20
...

```

and then use the translate plugin on each of these field.  
Can some one help me with this problems.  
also the number of data in the `field` are not always constant.

thanks

I would use ruby. Something like

```
ruby {
    code => '
        field = event.get("field")
        if field and field.is_a? Array
            field.each_index { |x|
                event.set("field.#{x+1}", field[x])
            }
        }
    '
}
```
