您好我是Powershell的新手，但我已经全神贯注地回答了这个问题，如何在PowerShell中将XML数据转换为CSV数据？

这是我的xml文件：

<users>
     <user>
        <id>"data"</id>
        <name>"data"</name>
        <disabled>"data"</disabled>
        <title>"data"</title>
        <email>"data"</email>
        <role>
             <name>"data"</name>
        </role>
        <custom_fields_values>
            <custom_fields_value>
                <custom_field_id>60019</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
            <custom_fields_value>
                <custom_field_id>60021</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
            <custom_fields_value>
                <custom_field_id>60018</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
        </custom_fields_values>
        <site>
            <name>"data"</name>
        </site>
    </user>
</users>

树中多层的字段是最大的痛苦。这是我到目前为止提出的脚本。我能够获得名称和电子邮件等基本字段。我真的需要标记自定义字段及其子集的字段。

#Converts the xml to a CSV file 
$samage_users.users.user | select-Object @(
@{l="Email";e={$_.email}},
@{l="Name";e={$_.name}},
@{l="ID";e={$_.ID}},
@{l="Phone";e={$_.phone}},
@{l="Site";e={$_.site.name}},
@{l="Reports_To";e={$_.reports_to.name}},
@{l="Reports_To_Email";e={$_.reports_to.email}})|
export-csv "Samanage_users.csv" -NoTypeInformation -Append
$page ++
start-sleep -s 10
}
While ($page -lt ($pages + 2))
}
Function NewUsers
{
foreach ($user in $new_user)
{

CSV输出文件应该如下所示。 （见附件）

您需要生成一个对象，类似于您现在的操作方式，但在输出之前，您需要为每个自定义字段添加属性。如果您的用户具有不同的自定义字段，则唯一的复杂功能就在于此。由于PowerShell不会输出数组中第一个项目的任何属性，因此您必须找到所有可能的属性，并将它们添加到第一个对象。这应该做你想要的我相当肯定。我已经使用不同的自定义字段（用60034替换60019）向XML添加了第二个用户以显示输出。

[xml]$samage_users=@'
<users>
        <user>
        <id>"data"</id>
        <name>"data"</name>
        <disabled>"data"</disabled>
        <title>"data"</title>
        <email>"data"</email>
        <role>
                <name>"data"</name>
        </role>
        <custom_fields_values>
            <custom_fields_value>
                <custom_field_id>60019</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
            <custom_fields_value>
                <custom_field_id>60021</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
            <custom_fields_value>
                <custom_field_id>60018</custom_field_id>
                <value>"data"</value>
            </custom_fields_value>
        </custom_fields_values>

                <value>"data2"</value>
            </custom_fields_value>
        </custom_fields_values>
        <site>
            <name>"data2"</name>
        </site>
    </user>
</users>
'@

$Results = ForEach($User in $samage_users.users.user) {
    $UserObject = [PSCustomObject][ordered]@{
        "Email" = $User.email
        "Name" = $User.name
        "ID" = $User.ID
        "Phone" = $User.phone
        "Site" = $User.site.name

$Results | FT *

输出是：

Email   Name    ID      Phone Site    Reports_To Reports_To_Email 60019  60021   60018   60034

"data2" "data2" "data2"       "data2"                                    "data2" "data2" "data2"

如果需要输出到文件，您可以轻松地将$Results传送到Export-Csv。

这是我对TheMadTechnician's answer的更改，并附有必要的解释说明：

$RObj = ForEach ($User in $samage_users.users.user) { 
  ### calculate basic properties - even those ones absent in XML
  $UObj = $user | Select-Object @(
    @{l="Email";e={$_.email}},
    @{l="Name";e={$_.name}},
    @{l="ID";e={$_.ID}},
    @{l="Phone";e={$_.phone}},
    @{l="Site";e={$_.site.name}},
    @{l="Rs_To";e={$_.reports_to.name}},   # "Rs_To"   cut "Reports_To"
    @{l="Rs_To_E";e={$_.reports_to.email}} # "Rs_To_E" cut "Reports_To_Email"
                                           # cuttings merely for better output readability
  )
  ### add user-dependent properties for each custom field 
    $User.custom_fields_values.custom_fields_value | 
      ForEach-Object {
        $UObj | Add-Member NoteProperty -Name $_.custom_field_id -Value $_.value
      }
    $UObj     ### add current PSCustomObject to the `$RObj` array
}
### mutually arrange potentially missing user-dependent properties
for ($i = 0; $i -lt $RObj.Count; $i++ ) {
 for ($j = 0; $j -lt $RObj.Count; $j++ ) {
  if ( $i -ne $j ) {
   $RObj[$i] | ForEach-Object { $_.PSObject.Properties.Name } | 
    Where-Object { $_ -notin $RObj[$j].PSObject.Properties.Name } | 
     ForEach-Object { 
        $RObj[$j] | Add-Member -MemberType NoteProperty -Name $_ -Value ''
     }
  }
 }
}
### $RObj | Export-Csv "Samanage_users.csv" -NoTypeInformation
### debugging output instead of `Export-Csv`
$RObj | Format-Table -Property * -AutoSize

注意关于Tomalak's useful comment声明应始终使用XmlDocument对象的.Load()方法读取XML文件。< / p> 

###                   $samage_users defined as above i.e. a herestring cast to [xml] type
