delete a object from the json file using a powershell - powershell

Question

In this Question i want to accomplish is that i am trying to delete a specific object in the json file.
But while doing so i am experiencing some difficulties i tried to refer article Iterate over JSON and remove JSON element in PowerShell
and implement the same but however it is deleting the entire element but i want to delete a specific object in the element not the entire element following are the required things
1. json file
{
"name": "JourneyPack",
"description": "Details of the journey across india",
"author": "Sachin",
"version": "1.0.0",
"main": "main.js",
"build": {
"applicationID": "desktop",
"Necessaryfiles": [
"main.js",
"package.json",
],
"Storage": {
"output": "./reunited"
},
"DeatilsOfJourney": [
{
"from": "../Pune",
"to": "../travel/Pune",
"filter": [
"**/*
]
},
{
"from": "../Delhi",
"to": "../travel/Delhi",
"filter": [
"**/*"
]
},
{
"from": "../Jharkhand",
"to": "../travel/Jharkhand",
"filter": [
"**/*"
]
},
],
"IOS": {
"category": "desktop"
},
"Windows": {
"icon": "images/desktopicons/icons.ico",
"target": [
"divfrieght"
],
"publisherName": [
"Sachin"
]
},
"divfrieght": {
"PointClick": true,
"standaloneMachine": true,
"allowrise": true,
"allowinstdir": true,
"menu": "JourneyPack"
}
},
"private": true,
}
following is the tried code again this is that i have referred from Iterate over JSON and remove JSON element in PowerShell
2. tried code
$inputFile = '<THE FULL PATH AND FILENAME TO YOUR JSON FILE>'
$outputFile = '<THE FULL PATH AND FILENAME FOR THE OUTPUT JSON FILE>'
$apijson = Get-Content -Path $inputFile -Raw | ConvertFrom-Json
# for safety, first make a copy of the original .paths object
$newPaths = $apijson.paths
foreach ($element in $newPaths.PSObject.Properties) {
$objName = $element.Name
$objValue = $element.Value
$objProperties = $objValue.PSObject.Properties
foreach ($prop in $objProperties) {
if ($prop.Value.'from' -eq 'Jharkhand') {
$propName = $prop.Name
$objProperties.Remove($propName)
Write-Host "Removed object $objName -- $propName"
}
}
}
# now overwrite the $apijson.paths with this cleaned up version
$apijson.paths = $newPaths
# I assume you want to convert it back to a .JSON file??
$apijson | ConvertTo-Json -Depth 100 | Set-Content -Path $outputFile -Force
i want to delete the object where "from" is equal to "../Jharkhand/"
Desired Output

if anyone could help that would be really helpful

Answer 1

".paths" property does not belong to you json file, so removed this part of your script.
# for safety, first make a copy of the original .paths object
$newPaths = $apijson.paths
Try this code:
$inputFile = 'input.json'
$outputFile = 'output.json'
$apijson = Get-Content -Path $inputFile -Raw | ConvertFrom-Json
foreach ($element in $apijson.PSObject.Properties) {
$objName = $element.Name
$objValue = $element.Value
$objProperties = $objValue.PSObject.Properties
foreach ($prop in $objProperties) {
# Your object lies in this array
if ($prop.Name -eq 'DeatilsOfJourney') {
[System.Collections.ArrayList]$arr = $prop.Value
#Iterate over your array and find that object which you want to remove
for ($i = 0; $i -lt $arr.count; $i++) {
if ($arr[$i].'from' -eq '../Jharkhand')
{
$arr.RemoveAt($i)
$i--
}
}
$prop.Value = $arr
}
}
}
$apijson | ConvertTo-Json -Depth 100 | Set-Content -Path $outputFile -Force
