[minhtrancccp]

 - v
 - [...]
 - b:
  - w
  - [...]
 - c:
  - x
  - [...]
  - d:
   - y
   - [...]
e:
 - z

You can do it by matching all the nodes, then filtering to only include scalar values:

yq '.. | select(kind == "scalar")' data1.yaml

This will not include empty maps and arrays. If you wanted to include those:

yq '.. | select(kind == "scalar" or length == 0)' data1.yaml
