read_element

Advances the cursor of the reader to the element of the array or the member of the object at the given position.

You can use [method@Json.Reader.get_value] and its wrapper functions to retrieve the value of the element; for instance, the following code will read the first element of the array at the current cursor position:

```c json_reader_read_element (reader, 0); int_value = json_reader_get_int_value (reader); ```

After reading the value, you should call [method@Json.Reader.end_element] to reposition the cursor inside the reader, e.g.:

```c const char *str_value = NULL;

json_reader_read_element (reader, 1); str_value = json_reader_get_string_value (reader); json_reader_end_element (reader);

json_reader_read_element (reader, 2); str_value = json_reader_get_string_value (reader); json_reader_end_element (reader); ```

If the reader is not currently on an array or an object, or if the index is bigger than the size of the array or the object, the reader will be put in an error state until [method@Json.Reader.end_element] is called. This means that, if used conditionally, [method@Json.Reader.end_element ] must be called on all branches:

```c if (!json_reader_read_element (reader, 1)) { g_propagate_error (error, json_reader_get_error (reader)); json_reader_end_element (reader ); return FALSE; } else { const char *str_value = json_reader_get_string_value (reader); json_reader_end_element (reader);

// use str_value

return TRUE; } ```c

Parameters:

this	a reader
index_	the index of the element

Returns:

`TRUE` on success, and `FALSE` otherwise
