Description

json_pointerjson_pointerJsonPointerjson_pointerJsonPointerJsonPointer uses a JSON Pointer to extract a value from a JSON string.

Further information about JSON pointers are available in the document RFC 6901 / JavaScript Object Notation (JSON) Pointer.

In contrast to queries with XPath as known from XML documents JSON pointers are restricted but also easy to use.

This example JSON data:

{
  "key1": "value1",
  "key2": {
      "c": 42,
      "b": [
          43,
          44
      ]
  }
}

can be accessed with JSON pointers as follows:

/key1 -> 'value1'
/key2/b/0 -> 43
/key2/c -> 42
