Adding new item into XML output file - powershell

Question

I would like to combined the external IP address with the current hardware information output file.
PC info
#lists computer information
$cpu = Get-WmiObject -Class Win32_Processor
$mb = Get-WmiObject -Class Win32_BaseBoard
$bios = Get-WmiObject -Class Win32_BIOS -ComputerName .
#$user = Get-WmiObject -Class Win32_ComputerSystem
$last = Get-WmiObject -class Win32_NetworkLoginProfile |
Where {($_.NumberOfLogons -gt 0) -and ($_.NumberOfLogons -lt 65535)} |
Select-Object Name,#{label='LastLogon';expression={$_.ConvertToDateTime($_.LastLogon)}},NumberOfLogons
$props = #{
"Name" = $cpu.Name
"Description" = $cpu.Description
"MB Manufacturer" = $mb.Manufacturer
"MB Product" = $mb.Product
"Bios Verison" = $bios.SMBIOSBIOSVersion
"Bios Manufacturer" = $bios.Manufacturer
"Bios Serial" = $bios.SerialNumber
"~Last Logon" = $last
}
New-Object PSObject -Property $props | Out-File c:\Windows\Script\PS_Output3.xml
External IP Address
$wc=New-Object net.webclient;
$wc.downloadstring("http://checkip.dyndns.com") -replace "[^\d\.]"
Update
One last question: how could I organize the list?

Answer 1

Something like this might help:
#lists computer information
$cpu = Get-WmiObject -Class Win32_Processor
$mb = Get-WmiObject -Class Win32_BaseBoard
$bios = Get-WmiObject -Class Win32_BIOS -ComputerName .
#$user = Get-WmiObject -Class Win32_ComputerSystem
$DyDNS = Invoke-WebRequest http://checkip.dyndns.com/ -DisableKeepAlive
$Dyreg = $DyDNS.RawContent -match '\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b'
$last = Get-WmiObject -class Win32_NetworkLoginProfile | Where {($_.NumberOfLogons -gt 0) -and ($_.NumberOfLogons -lt 65535)} | Select-Object Name,#{label='LastLogon';expression={$_.ConvertToDateTime($_.LastLogon)}},NumberOfLogons
$props = #{
"Name" = $cpu.Name
"Description" = $cpu.Description
"MB Manufacturer" = $mb.Manufacturer
"MB Product" = $mb.Product
"Bios Verison" = $bios.SMBIOSBIOSVersion
"Bios Manufacturer" = $bios.Manufacturer
"Bios Serial" = $bios.SerialNumber
"~Last Logon" = $last
"DNS" = $matches[0]
}
New-Object PSObject -Property $props | Out-File C:\test.csv
