How to delete webparts from the main page in sharepoint using powershell - powershell

Question

I have the following code which adds a webpart, but i need some way to delete all the webparts before this runs. Anybody know how to do this? I have tried multiple ways, but am brand new to powershell and sharepoint and have no idea what i am doing.
$wpm = $file.GetLimitedWebPartManager([Microsoft.SharePoint.Client.WebParts.PersonalizationScope]::Shared)
$sortedNodes = $pageXml.Module.File.AllUsersWebPart | sort { $_.WebPartZoneID, [int] $_.WebPartOrder }
write-host $sortedNodes
write-host $sortedNodes.Count
foreach ($webPartXml in $sortedNodes)
{
$zoneId = $webPartXml.WebPartZoneID
$zoneIndex = $webPartXml.WebPartOrder
$xml = $webPartXml.InnerText
$wpd = $wpm.ImportWebPart($xml)
$wpd = $wpm.AddWebPart($wpd.WebPart, $zoneId, $zoneIndex)
"Adding a web part to the [$zoneId] zone, [$zoneIndex] position..."
try
{
Submit-ExecuteQuery $context
}
catch
{
Write-Host "The following error occurred while trying to add the web part: $($_.Exception.Message)" -ForegroundColor Red
}
}

Please try the following:
$wpm = $file.GetLimitedWebPartManager([Microsoft.SharePoint.Client.WebParts.PersonalizationScope]::Shared)
<# Remove All Webparts - Begin #>
foreach ($webPart in $wpm.WebParts)
{
$wpdD = New-Object Microsoft.SharePoint.Client.WebParts.WebPartDefinition
$context.Load($webPart)
$wpdD = $webPart
$wpdD.DeleteWebPart();
try
{
Submit-ExecuteQuery $context
}
catch
{
Write-Host "The following error occurred while trying to add the web part: $($_.Exception.Message)" -ForegroundColor Red
}
}
<# Remove All Webparts - End #>
$sortedNodes = $pageXml.Module.File.AllUsersWebPart | sort { $_.WebPartZoneID, [int] $_.WebPartOrder }
write-host $sortedNodes
write-host $sortedNodes.Count
foreach ($webPartXml in $sortedNodes)
{
$zoneId = $webPartXml.WebPartZoneID
$zoneIndex = $webPartXml.WebPartOrder
$xml = $webPartXml.InnerText
$wpd = $wpm.ImportWebPart($xml)
$wpd = $wpm.AddWebPart($wpd.WebPart, $zoneId, $zoneIndex)
"Adding a web part to the [$zoneId] zone, [$zoneIndex] position..."
try
{
Submit-ExecuteQuery $context
}
catch
{
Write-Host "The following error occurred while trying to add the web part: $($_.Exception.Message)" -ForegroundColor Red
}
}
