Hi,
It depends on how the gpo is stored in the xml file. According to the result you posted, there could be three nodes in $x.GPO.Computer.ExtenstionData.Extension and you can get them separately with $x.GPO.Computer.ExtenstionData.Extension[0], $x.GPO.Computer.ExtenstionData.Extension[1] and $x.GPO.Computer.ExtenstionData.Extension[2]. You'd better post the xml file. Otherwise no one knows how to get the data inside these nodes.
Best Regards,
Ian
