I get the following JSON result from an external system:
{
"key1": "val1",
"key2": "val2",
"key3": "val3"
}
Now I want to display all keys and all values by using JSONPath. So I am looking for something to get key1, key2 and key3 as a result. Additionally I would like to use the index of a property, e. g. $....[2].key
to get "key3" etc. Is there a way to do something like this?
I found that the tilda ~
symbol is able to retrieve the keys of the values it's called upon. So for your example a query like this:
$.*~
Returns this:
[
"key1",
"key2",
"key3"
]
Another example, if we had a JSON document like this:
{
"key1": "val1",
"key2": "val2",
"key3": {
"key31":"val31",
"key32":"val32"
}
}
A query like this:
$.key3.*~
Would return this:
[
"key31",
"key32"
]
It's important to note that these examples work on JSONPath.com and some other simulators/online tools, but on some they don't. It might come from the fact that I found out about the tilda(~) operator in the JSONPath plus documentation and not the official one.
