Demonstrates how to swap two JSON objects within a JSON document.

Note: This example requires Chilkat v9.5.0.76 or greater.

oleobject loo_Json
integer li_Success
integer li_Index1
integer li_Index2

// Use "Chilkat_9_5_0.JsonObject" for versions of Chilkat < 10.0.0

// Load the following JSON:

// {

//     "gender": "male",
//     "country": "US"
//   },

//     "country": "UK"

li_Success = loo_Json.LoadFile("qa_data/json/people.json")
// Assume success..

// Swap the positions of Jon and Sara.
li_Index1 = loo_Json.IndexOf("Jon")
li_Index2 = loo_Json.IndexOf("Sara")
loo_Json.Swap(li_Index1,li_Index2)

// We have this now:
Write-Debug loo_Json.Emit()

// {

//     "DOB": "13/05/1982",
//     "gender": "female",
//     "country": "FR"
//   }

// To swap an inner member:

li_Index1 = loo_JsonSara.IndexOf("DOB")
li_Index2 = loo_JsonSara.IndexOf("country")
loo_JsonSara.Swap(li_Index1,li_Index2)

// We now have this:
Write-Debug loo_Json.Emit()

// {
//   "petter": {
//     "DOB": "26/02/1986",
//     "gender": "male",
