Answer 1

You can get parent element from an attribute via OwnerElement property. So this is one possible way to get the desired output :

$model.SelectNodes("//item/@*") |
    ForEach {
        # set attributes value on `model` element
        $_.OwnerElement.ParentNode.ParentNode.SetAttribute($_.LocalName, $_.Value)
        # remove attributes except `name` from `item` element
        If ($_.LocalName -ne "name") { $_.OwnerElement.RemoveAttribute($_.LocalName) }
    }
