Hi folks,

I have following key:

`key = "value1/value2/value3"`

or

`key = "value1/value2/value3/value4"`

I want to split this to following structure:

```auto
key1: value1
key2: value2
key3: value3

```

This would be easy by using a grok like

`%{WORD:key1}/%{WORD:key2}/%{GREEDYDATA:key3}` (greedydata because I want to get everything after value3 in one field).

However this works only when there is the delimiter `"/"` at the end of the string I cannot manage to make this grok work for both scenarios: When there are 3 values ore more than 3. Do you have an Idea how I can make this grok work?
