I need some help with the <AutoImportExpressionFilter> xml structure for adding interface nodes during discovery based on a regex filter.   Is there someone that could provide an update to the syntax in my script below?   I have tried a few different ways however nothing seems to change in the interface discovery settings on the console.  Thanks! 

# Swis connection info

$OrionServer = "localhost"

# Discovery parameters

$ipAddresses = @("10.99.248.10","10.99.248.11")

$ipList = @() 

foreach ($ip in $ipAddresses) { 

    $ipList += '<IpAddress><Address>{0}</Address></IpAddress>' -f ($ip) 

} 

$snmpv3_network = "Network v3"

$snmpv3_voice = "Voice"

$engindId = 1

$DeleteProfileAfterDiscoveryCompletes = "false"

$swis = Connect-Swis $OrionServer -Trusted

# Get the ID of the named SNMPv3 credential

$snmpv3_network_id = Get-SwisData $swis "SELECT ID FROM Orion.Credential WHERE Name=@name" @{name = $snmpv3_network}

$snmpv3_voice_id = Get-SwisData $swis "SELECT ID FROM Orion.Credential WHERE Name=@name" @{name = $snmpv3_voice}
