Powershell & WSUS Updates

can someone help me out here? I'm trying to get WSUS updates via powershell with the command:
$WsusServerAdminProxy.GetUpdates() | ?{-not $_.IsDeclined -and $_.ProductTitles -match "Windows XP” }

That's listing all Updates for Windows XP correctly.. but it lists also the Updates which are for "Windows XP, Windows 2003". But I'd would only decline the updates which are for XP only.

I tried to reach that so: Change -match "Windows XP"  to -eq "Windows XP”, or -like "Windows XP” , but nothing worked.

[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null
$WsusServerAdminProxy = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($WsusServer,$UseSSL,$PortNumber);
$updates = $WsusServerAdminProxy.GetUpdates() | ?{-not $_.IsDeclined -and $_.ProductTitles -like "Windows XP” }

luckily the ProductTitles don't count two for XP 32bi and XP 64bit, because this are separate updates. Otherwise it wouldn't work.
