Thanks again Pieter!
I tried that, but it only returns the answer to the question, not the name of the question.
Anyway now i have tried to get a grip on how to use the xpath-trick. I am stuck on the last step where the result is mapped in the select action. In the example you linked only the column names are stored in the final array.
I would like to go from this (where i am right now)
{
"root": {
"a": 1,
"b": 2,
"c": 3
}
} to this
[
1,
2,
3
]
Instead of as in the example:
[
"a",
"b",
"c"
]
