Loading and Parsing a JSON Array

See more JSON Examples

A JSON array is JSON that begins with "[" and ends with "]". For example, this is a JSON array that contains 3 JSON objects.

[{"name":"jack"},{"name":"john"},{"name":"joe"}]

A JSON object, however, is JSON that begins with "{" and ends with "}". For example, this JSON is an object that contains an array.

{"pets":[{"name":"jack"},{"name":"john"},{"name":"joe"}]}

This example shows how loading a JSON array is different than loading a JSON object. Chilkat2-Python

import chilkat2

strJsonArray = "[{\"name\":\"jack\"},{\"name\":\"john\"},{\"name\":\"joe\"}]"

strJsonObject = "{\"pets\":[{\"name\":\"jack\"},{\"name\":\"john\"},{\"name\":\"joe\"}]}"

# A JSON array must be loaded using JsonArray:
jsonArray = chilkat2.JsonArray()
jsonArray.Load(strJsonArray)

# Examine the values:
i = 0
while i < jsonArray.Size :
    # jsonObj is a CkJsonObject
    jsonObj = jsonArray.ObjectAt(i)
    print(str(i) + ": " + jsonObj.StringOf("name"))

    i = i + 1

# Output is:

# 	0: jack
# 	1: john
# 	2: joe

# A JSON object must be loaded using JsonObject
jsonObject = chilkat2.JsonObject()
jsonObject.Load(strJsonObject)

# Examine the values:
i = 0
numPets = jsonObject.SizeOfArray("pets")
while i < numPets :
    jsonObject.I = i
    print(str(i) + ": " + jsonObject.StringOf("pets[i].name"))
    i = i + 1

# Output is:

# 	0: jack
# 	1: john
# 	2: joe
