Each XML property is converted to an object property with a value of datetime, double, integer or string. .INPUTS [System.XML.Xmlelement []] .OUTPUTS [System.Object[]] .EXAMPLE $element | ConvertFrom-XML Converts variable $element with must contain 1 or more Xml.Xmlelements to custom PSobjects with the same content. .NOTES NAME: ConvertFrom-XML #> [cmdletbinding()] Param ( [Parameter( Mandatory = $true, ValueFromPipeLine = $true, ParameterSetName = 'Input_Object' )] [Xml.Xmlelement[]] $InputObject ) begin { # Enable modern -Debug behavior if ($PSCmdlet.MyInvocation.BoundParameters['Debug'].IsPresent) { $DebugPreference = 'Continue' } Write-Debug ('{0}: Begin of function' -F $MyInvocation.MyCommand.Name) $result = @() # Set up TimeZone offset handling if (-not($script:ESTzone)) { $script:ESTzone = [System.TimeZoneInfo]::FindSystemTimeZoneById("Eastern Standard Time") } if (-not($script:ESToffset)) { $now = Get-Date $ESTtime = [System.TimeZoneInfo]::ConvertTimeFromUtc($now.ToUniversalTime(), $ESTzone) $script:ESToffset = (New-TimeSpan -Start $now -End $ESTtime).TotalHours } } process { foreach ($element in $InputObject) { # Get properties $properties = $element | Get-Member -MemberType property # Create a new, empty object $object = New-Object -TypeName PSObject # Loop through all properties and add a member for each foreach ($property in $properties) { # We are accessing property values by dynamic naming.
