Given one object (“netto”) specifying which properties from another object (“brutto”) should be extracted into a new resulting object:

{
  "brutto": {
    "a": "AAA",    
    "b": "BBB",    // Excluded from the result as "netto" doesn't include "b"
    "c": "CCC"     
  },
  "netto": {
    "a": true,
    "c": true 
  } 
}

When: Some JsonPath expression checking which field names in “brutto” are also present in “netto”

Then:

{
  "a": "AAA",
  "c": "CCC"
}

Is it possible to do the with JsonPath and if so – what would the JsonPath (Jayway) expression look like?
