 $publishingWeb = [Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($web)
 $publishingPages = $publishingWeb.GetPublishingPages()
 foreach ($publishingPage in $publishingPages)
 {
  $file = $web.GetFile($publishingPage.Uri.ToString())

  [Microsoft.SharePoint.SPListItem]$spListItem = $file.Item
