Question

我创建了一个脚本来遍历我们的用户目录并修改XML文档以更改应用程序中的设置。通常当我使用foreach时，它会使我的变量=来自集合的一个项目。相反，此脚本会将$XMLPaths中的所有内容放入我的$Path变量。

$XMLPaths = Get-ChildItem \\DFSRoot\DFSShare\view\Profiles\*\AppData\Roaming\Trillian\ -Recurse -Force |
            Where-Object {$_.Name -contains 'Events.xml'} |
            Select FullName |
            FT -HideTableHeaders |
            Out-String

foreach ($Path in $XMLPaths) {
  $xml = [xml](Get-Content $Path)
  $node = $xml.events.prefs.setting | Where {$_.Name -eq 'Sounds'}
  $node.value = '1'
  $XML.Save($Path)
  $Path
  $node
}

这是我正在使用的XML文档。

变量$Path一次只能有一个目录，而不是它。

\\DFSROOT\DFSSHare\view\Profiles\User1\AppData\Roaming\Trillian\users\User1\Events.xml
\\DFSROOT\DFSSHare\view\Profiles\User2\AppData\Roaming\Trillian\users\User2\Events.xml
\\DFSROOT\DFSSHare\view\Profiles\User3\AppData\Roaming\Trillian\users\User3\Events.xml
\\DFSROOT\DFSSHare\view\Profiles\User4\AppData\Roaming\Trillian\users\User4\Events.xml
\\DFSROOT\DFSSHare\view\Profiles\User5\AppData\Roaming\Trillian\users\User5\Events.xml

Answer 1

问题在于，生成的$XMLPaths变量是字符串而不是数组。因此，您的ForEach表达式将变量$XMLPaths解释为一个元素的数组，其中一个元素是一个包含所有连接在一起的路径的字符串。

您可以随时输入$Variable来检查变量$Variable.GetType()的类型。例如，当我运行你的第一行代码时，这就是我所看到的：

PS > $XMLPaths.GetType()

IsPublic IsSerial Name    BaseType
-------- -------- ----    --------
True     True     String  System.Object

尝试用这个替换第一行：

#Remote Computers
$XMLPaths = (Get-ChildItem \\DFSRoot\DFS Share\view\Profiles\*\AppData\Roaming\Trillian\ -Recurse -Force | Where-Object {$_.Name -contains 'Events.xml'} | Select FullName).FullName

在Select FullName子句之后，返回包含属性FullName的对象数组。因此，通过调用.FullName，它返回一个文件名数组。

您应该能够检查$XMLPaths是否为array类型：

PS > $XMLPaths.GetType()

IsPublic IsSerial Name      BaseType
-------- -------- ----      --------
True     True     Object[]  System.Array

Answer 2

$XMLPaths.GetType().Name返回String。使用

$auxiliaryPath = "\\DFSRoot\DFS Share\view\Profiles\*\AppData\Roaming\Trillian"
$XMLPaths = (Get-ChildItem "$auxiliaryPath\Events.xml" -Recurse -Force).FullName

使用Powershell使用Foreach修改多个XML文档
