How can I split a nested yaml into multiple files by iterating through multiple keys?

[dmc-94]

Hi there,

I want to split a big yaml file into multiple yaml files. I looked into the QA with following example: #1562 but I can not really figure it out, as I don't understand how to double loop through this file.

I have following data

regions:
  region1:
    item1:
      settingA: null
      settingB: null
    item2:
      - value1
      - value2
  region2:
    item1:
      settingA: something
      settingB: configured
    item2:
      - value1
      - value2

I basically need to split the files by region and item.

So in the end this example should generate 4 yaml files like region1_item1.yaml , region1_item2.yaml, region2_item1.yaml and so on..

And the content should always be a key and the values of the region map:

region1_item1.yaml

item1:
  settingA: null
  settingB: null

Any help is appreciated. Thank you!
