在 Powershell 中使用循环在 XML 文件中添加元素

Question

我有一个 XML 文件，我从 Powershell 上的以下代码中获取该文件，然后将其转换为 CSV 以在网格视图中获得所需的输出

    foreach($u in $global:Server) {
            $ret=(Invoke-SSHCommand -Index 0 -Command "mccli backup show --name=/clients/$u --verbose=true --xml | tee -a /tmp/backup.xml")
            
            } 
    Get-SCPFile -ComputerName "$global:Avamar" -Credential $LoginCredentials -RemoteFile "/tmp/backup.xml" -LocalFile 'C:\Temp\backup.xml'
        [xml]$log = "<logroot>$(Get-Content C:\Temp\backup.xml)</logroot>"
        $log.logroot.CLIOutput.Data.ChildNodes | ConvertTo-Csv -NoTypeInformation -Delimiter "," | Set-Content "C:\Temp\new.csv"
Import-Csv -Path "C:\Temp\new.csv" | Out-GridView -Title Get-CsvData

backup.xml 文件如下所示

我想在 XML 输出文件中获取或附加客户端名称，以明确哪一行属于哪个客户端。

如果我对你的理解正确，就更新你的 xml 而言，你可能正在寻找这样的东西：

$xmlFragment=$log.CreateDocumentFragment()
$clients = 'Sample1.com','Sample2.com'    
$targets = $log.selectnodes('//Data')

for ($i = 0; $i -lt $targets.Count; $i++) {
    $rows = $targets[$i].selectnodes(".//Row")
    $item = $clients[$i]
    $new_node = "<client>$item</client>"    
    foreach ($row in $rows) {
        $xmlFragment.InnerXML=$new_node
        $row.PrependChild($xmlFragment)
    }
}
