Refer to this code to update entityID value in ExpireRequirements task element (specify config file path in argument:-webCofig xxx):
param(
[string]$webConfig
)
$doc = (Get-Content $webConfig) -as [Xml]
$root=$doc.get_DocumentElement()
$ExpireRequirementsTask=$root."service.tasks"."tasks"."task" | where {$_.name -eq 'ExpireRequirements'}
Write-Output $ExpireRequirementsTask
$ExpireRequirementsTaskEntityID=$ExpireRequirementsTask."parameters"."param" | where {$_.key -eq 'entityID'}
Write-Output $ExpireRequirementsTaskEntityID
$ExpireRequirementsTaskEntityID.InnerText="11111111-0000-0000-0000-000000000E01"
$doc.Save($webConfig)
