Is there a way to get the path from the fetch about jsonpath HOT 5 CLOSED

The placeholder # without a number is a hack and it works only for the wildcard parts so you have to add the c manually:

` builder := jsonpath.PlaceholderExtension()

path, err := builder.NewEvaluable(`{#: $..c}`)
if err != nil {
	fmt.Println(err)
	os.Exit(1)
}

v := interface{}(nil)
err = json.Unmarshal([]byte(`{ "a": { "b": { "c": 1, "d": 2 } } }`), &v)

if err != nil {
	fmt.Println(err)
	os.Exit(1)
}

devices, err := path(context.Background(), v)
if err != nil {
	fmt.Println(err)
	os.Exit(1)
}

for device, name := range devices.(map[string]interface{}) {
	fmt.Printf("%s -> %v\n", device, name)
}

// Unordered output:
// $["a"]["b"] -> 1`

Actually palceholders should be used like #0 or #1 to access the nth key or in case of .. an array of the keys. (see the gval example in godoc)

Hi moshevi,

in this package is an extension for placeholders. This isn't official json path anymore but it helps to access the keys.

The path {#: $..x} will return a map[string]interface{} from jsonpath to value. In this case $["a"]["b"]["c"]

from jsonpath.

Hi @generikvault
Can you send me a code sample for that?
Thanks.

Thanks @generikvault

@generikvault Is there any samples for using regex for jsonpath or gval?
