Powershell import-csv拆分和匹配单元格内容

Question

我有一个包含3列和多行的CSV。每个3 x个相邻单元（每行）在单元中有多行数据，每个相邻单元的行数始终相同。

原始CSV数据：

NodeName,NodeAddress,NodeAdressDR
"1.com
2.com
3.com
4.com","10.173.5.210
10.173.5.212
10.173.5.214
10.173.5.216","10.49.245.210
10.49.245.212
10.49.245.214
10.49.245.216"
"5.com
6.com
7.com
8.com","10.173.5.203
10.173.5.205
10.173.5.207","10.49.245.203
10.49.245.205
10.49.245.207"
,,

这可以使用以下方法，但有一种更简单的方法可以满足每个单元的不确定数量的主机名/ IP，而无需创建单独的变量，即每行一个？

$csvImportFull = Import-CSV .\CSVFile.csv
foreach ($headingFull in $csvImportFull)

{
$nodeName = $headingFull.("NodeName")
$nodeAddress =$headingFull.("NodeAddress")
$nodeAddressDR = $headingFull.("NodeAddressDR")

$NodeName1 = ($nodeName -split "\n")[0]
$NodeName2 = ($nodeName-split "\n")[1]
$NodeName3 = ($nodeName-split "\n")[2]
$NodeName4 = ($nodeName -split "\n")[3]

$NodeAddress1 = ($nodeAddress -split "\n")[0]
$NodeAddress2 = ($nodeAddress -split "\n")[1]
$NodeAddress3 = ($nodeAddress -split "\n")[2]
$NodeAddress4 = ($nodeAddress -split "\n")[3]

$NodeAddressDR1 = ($nodeAddressDR -split "\n")[0]
$NodeAddressDR2 = ($nodeAddressDR -split "\n")[1]
$NodeAddressDR3 = ($nodeAddressDR -split "\n")[2]
$NodeAddressDR4 = ($nodeAddressDR -split "\n")[3]

write-host $NodeName1 NodeAddress1
write-host $NodeName1 NodeAddressDR1
write-host $NodeName2 NodeAddress2
write-host $NodeName1 NodeAddressDR2
}

因此，您可以迭代分割并创建新的对象列表，而不是硬编写变量：

$objects = @()

Import-CSV .\CSVFile.csv| ForEach-Object {
    $names = $_.NodeName -split '\r\n'
    $address = $_.NodeAddress -split '\r\n'
    $addressDr = $_.NodeAdressDR -split '\r\n'

    for($i = 0; $i -le 4; $i++)
    {
        $objects += [PsCustomObject]@{                
        NodeName = $names[$i]
            NodeAddress = $address[$i]
            NodeAddressDr = $addressDr[$i]
        }
    }
}

现在您有一个对象列表，其中每个对象都有NodeName，NodeAddress和NodeAddressDR

所以你可以这样做：

$objects | where NodeName -eq '1.com'

输出：

NodeName NodeAddress  NodeAddressDr
-------- -----------  -------------
1.com    10.173.5.210 10.49.245.210
