Question

此代码使用新值覆盖所有旧值;我需要一个代码来附加旧值。

<Code For Termset>
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Taxonomy")
$site = Get-SPSite http://invi28apps9c
$session = New-Object Microsoft.SharePoint.Taxonomy.TaxonomySession($site)
$termStore = $session.TermStores["Managed Metadata Service"]
$group = $termStore.Groups["KB"]
$termSet = $group.TermSets["IPS Document type"]     
$terms = $termSet.GetTerms(100)
$term = $terms | ?{$_.Name -eq "Docset"}

$web = Get-SPWeb http://invi28apps9c/DemoTeamSite
$list = $web.Lists["KBDocument"]

$query = New-Object Microsoft.SharePoint.SPQuery
 $query.ViewAttributes = "Scope='Recursive'";
$query.RowLimit = 2000
 $caml = "<Where> 
  <Eq>
     <FieldRef Name='DocIcon'/>
     <Value Type='Computed'>.zip</Value>

  </Eq>
    </Where>"
 $query.Query = $caml 

  do
    {
$listItems = $list.GetItems($query)
$spQuery.ListItemCollectionPosition = $listItems.ListItemCollectionPosition

foreach($item in $listItems)
{

    $spItem = [Microsoft.SharePoint.SPListItem]$item;


    $taxField =     [Microsoft.SharePoint.Taxonomy.TaxonomyField]$spItem.Fields["Document Type"]


   $taxField.SetFieldValue($spItem,$term)
    $spItem.Update()
}
   }
  while ($spQuery.ListItemCollectionPosition -ne $null)

当您访问该字段的值时，您应该收到一个TaxonomyFieldValueCollection对象。此对象具有Add()方法，您可以使用该方法向其添加术语。

$value = $spItem["Document Type"]
$value.Add($term)
$spItem["Document Type"] = $value
$spItem.Update()

如何使用PowerShell仅为.Zip文件更新文档库中的托管元数据字段？
