Removing item form JSON in powershell - powershell

Question

I got a question to ask for removing an object in Json in powershell. I am fetching my results from powershell and i compressed it and placed into a JSON as shown below
foreach ($vm in $vms) {
$id = $vm.Config.InstanceUuid
$vmname = $vm.Config.Name
$geturl = "https://$nsxmanager/api/v1/fabric/virtual-machines?external_id=$id&included_fields=tags"
$getrequest = Invoke-RestMethod -Uri $geturl -Authentication Basic -Credential $nsxtcred -Method Get -ContentType "application/json" -SkipCertificateCheck
$getresult = $getrequest.results | ConvertTo-Json -Compress
Write-Host ($getresult)
}
This will get the results
{"tags":[{"scope":"allow_access","tag":"external"}, {"scope":"test","tag":"text"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
{"tags":[{"scope":"allow_access","tag":"external"}]}
I am trying to remove the element {"scope":"allow_access","tag":"external"} from all these results.
im not sure how i can remove it and wanted to seek some advice here how can I do so ?

You can try filtering out these results by converting your JSON results to a PSCustomObject, iterating through the Tags attribute in a nested Foreach loop, and building a new PSCustomObject that does not contain those results you would like to filter:
$getresult = $getresult | ConvertFrom-Json
$FilteredTagsArr = #()
Foreach($Tag in $GetResult.Tags){
If($Tag.scope -eq 'allow_access' -and $Tag.tag -eq "external"){
#Do Nothing
}Else{
$NewObj = [PSCustomObject]#{
Tag = $tag.tag
Scope = $tag.scope
}
$FilteredTagsArr += $NewObj
}
}
$GetResult.Tags = $FilteredTagsArr
Return $GetResult | ConvertTo-Json
