PowerShell的：合併有不同的數據線在一個CSV文件

Question

我是新來的PowerShell和仍然在學習，

我有一個CVS文件看起來像這樣： https://dl.dropboxusercontent.com/u/95418691/example.png

的MAC地址和VLAN去與上面的行，但我似乎無法找到一種方法來做到這一點，因爲不是每一行都有一個mac地址列出。我從一個奇怪的XML使這個CVS文件與此代碼：

$XML | 
    select-xml -xpath "/SolarWinds_SwitchPortMap/Interfaces/Interface | 
    /SolarWinds_SwitchPortMap/Interfaces/Interface/MACs/MAC" | 
    select -ExpandProperty Node | 
    select -Property Interface, Description, MACAddress, ip, DNS, VLAN, Speed | 
    Export-Csv -NoTypeInformation -Path "c:\Users\$env:username\Desktop\$ip.csv" 

因此修復這些代碼或寫別的東西CVS的線條相結合的兩種方式將是巨大的，並且如果不介意解釋您的解決方案，我正在努力學習:)謝謝。

編輯： 這是XML的樣子：

<SolarWinds_SwitchPortMap Layer2Device="<info>"> 
    <Interfaces> 
     <Interface ifIndex="<info>" CollectionTime="<info>" ConnectorPresent="<info>" Duplex="<info>" HardwareType="<info>" ifAdminStatus="<info>" ifAdminStatustest="<info>" Description="*** Frame 1 ***" ifDescr="<info>" MTU="<info>" Interface="<info>" ifOperStatus="<info>" ifSpeed="<info>" ifType="<info>" ifTypeName="<info>" InBitsSec="<info>" InPktsSec="<info>" LastChange="<info>" LastPacketIn="<info>" LastPacketOut="<info>" ModulePortIndex="<info>" OutBitsSec="<info>" OutPktSec="<info>" Port="<info>" TrunkPort="False">

嘗試是這樣的：

$csv = "$env:USERPROFILE\Desktop\$ip.csv" 
$expr = '/SolarWinds_SwitchPortMap/Interfaces/Interface' 

$XML | Select-Xml -XPath $expr | select -Expand Node | % { 
    New-Object -Type PSCustomObject -Property @{ 
    "Interface" = $_.Interface; 
    "Description" = $_.Description; 
    "Speed"  = $_.ifSpeed; 
    "MACAddress" = $_.MACs.MAC.MACAddress; 
    "IPAddress" = $_.MACs.Mac.ip; 
    "DNS"   = $_.MACs.MAC.DNS; 
    "VLAN"  = $_.MACs.MAC.VLAN; 
    } 
} | Export-Csv $csv -NoTypeInformation
