Powershell - 无法比较Sharepoint列表中的字符串输出

Question

从SharePoint中提取列表后，我需要根据其值BRTeam验证每个项目。这里是脚本：

cls 
if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq $null) { 
    Add-PSSnapin Microsoft.SharePoint.PowerShell; 
} 

$sourceWebUrl = "http://theoracle/WorkingHere/" 
$sourceListName = "Policies & Procedures" 

$spSourceWeb = Get-SPWeb $sourceWebUrl 
$spSourceList = $spSourceWeb.Lists[$sourceListName] 

$spSourceItems = $spSourceList.Items 

$spSourceItems | ForEach-Object { 
    Write-Host $_['Name'] 
    Write-Host $_['BRTeam'] 
} 

该代码在获取数据和将所需项目写入主机方面工作正常。

但是，如果我添加下面的if语句来验证的项目，我看到了一个错误：

if ($_['BRTeam'].Contains('HR')) { 
    Write-Host $_['Name'] 
    Write-Host $_['BRTeam'] 
} 

我也曾尝试分配$x = $_['BRTeam']后$x -contains 'HR'更换布尔检查，但是这不返回输出（也没有错误）。错误如下：

Method invocation failed because [Microsoft.SharePoint.Taxonomy.TaxonomyFieldValue] doesn't contain a method named 'Contains'. 
At line:21 char:9 
+  if ($_['BRTeam'].Contains('HR')) { 
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : InvalidOperation: (:) [], RuntimeException 
    + FullyQualifiedErrorId : MethodNotFound 

任何人都可以让我知道我在这里失踪了吗？

我能够通过使用-Match操盘手来解决此问题：

$spSourceItems | ForEach-Object { 
    #Write-Host $_['ID'] 
    #Write-Host $_['Workflow Started'] 
    $x = $_['BRTeam'] 

    if ($_['BRTeam'] -Match 'HR') { 
     Write-Host $_['Name'] 
    }  
} 

如果我担心的是其他一些BRTeams可能包含HR而不实际是HR，我也对所有的执行-notmatch其他部门。

例如为：

$spSourceItems | ForEach-Object { 
    #Write-Host $_['ID'] 
    #Write-Host $_['Workflow Started'] 
    $x = $_['BRTeam'] 

    if ($_['BRTeam'] -Notmatch 'Accounts' -And $_['BRTeam'] -Notmatch 'IT') { 
     Write-Host $_['Name'] 
    }  
}
