我有两个针对 xml 文件的单独查询，当我单独运行它们时，它们工作正常。但是，当我在同一个脚本中运行它们时，第二个查询的输出不正确。

输入文件如下所示：

<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<Safex>
    <Add>
        <User folder="/" name="D2\\[email protected]">
            <GroupMembership>ADMINS</GroupMembership>
            <GroupMembership>WebService</GroupMembership>
        </User>
        <User folder="/" name="D2\\[email protected]">
            <GroupMembership>WebService</GroupMembership>
        </User>
        <User folder="/" name="D2\\[email protected]">
            <GroupMembership>WebService</GroupMembership>
        </User>
        <User folder="/" name="D2\\[email protected]">
            <GroupMembership>ADMINS</GroupMembership>
        </User>
        <User folder="/" name="D2\\[email protected]">
            <GroupMembership>WebService</GroupMembership>
        </User>
    </Add>
</Safex>

我的脚本如下：

[xml]$xml = Get-Content $InputPath\test002.xml 

$a = $xml.Safex.Add.User | ForEach-Object {
    [PSCustomObject]@{
        'Name' = $_.name
        'Group' = $_.GroupMembership
    }
}
$a 


$b = $xml.Safex.Add.User | Where-Object { $_.GroupMembership -eq 'WebService' } | 
                           Select-Object @{Name = 'Name'; Expression = {$_.Name}}, GroupMembership

#$b

当我注释掉 $b 时，$a 将返回以下内容：

Name               Group               
----               -----               
D2\\[email protected]    {ADMINS, WebService}
D2\\[email protected]   WebService          
D2\\[email protected]  WebService          
D2\\[email protected]   ADMINS              
D2\\[email protected] WebService

当我注释掉 $a 时，$b 将返回以下内容：

Name               GroupMembership     
----               ---------------     
D2\\[email protected]    {ADMINS, WebService}
D2\\[email protected]   WebService          
D2\\[email protected]  WebService          
D2\\[email protected] WebService

当我取消注释 $a 和 $b 时，我得到以下结果：

Name               Group               
----               -----               
D2\\[email protected]    {ADMINS, WebService}
D2\\[email protected]   WebService          
D2\\[email protected]  WebService          
D2\\[email protected]   ADMINS              
D2\\[email protected] WebService          
D2\\[email protected]                        
D2\\[email protected]                       
D2\\[email protected]                      
D2\\[email protected]

我似乎无法弄清楚为什么当 $a 和 $b 都被取消注释时，$b 的标题不会出现，并且 GroupMembership 值也不会出现。

感谢您提供的任何帮助。
