使用 PowerShell 将原始 XML 回显到文件中 - 引号被删除

Question

我正在尝试使用以下命令通过 powershell 创建 Windows 计划任务 (XML) 文件：

$userName = $ENV:USERNAME
$compName = $ENV:COMPUTERNAME

echo "<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
  <RegistrationInfo>
    <Date>2014-10-09T14:28:16</Date>
    <Author>$userName</Author>
  </RegistrationInfo>
  <Triggers>


    <TimeTrigger>
      <Repetition>
        <Interval>PT2M</Interval>
        <StopAtDurationEnd>false</StopAtDurationEnd>
      </Repetition>
      <StartBoundary>2014-10-09T14:28:00</StartBoundary>
      <Enabled>true</Enabled>
    </TimeTrigger>
  </Triggers>
  <Principals>
    <Principal id="Author">
      <UserId>$compName\$userName</UserId>
      <LogonType>InteractiveToken</LogonType>
      <RunLevel>LeastPrivilege</RunLevel>
    </Principal>
  </Principals>
  <Settings>
    <MultipleInstancesPolicy>IgnoreNew</MultipleInstancesPolicy>

    <StopIfGoingOnBatteries>false</StopIfGoingOnBatteries>
    <AllowHardTerminate>true</AllowHardTerminate>
    <StartWhenAvailable>false</StartWhenAvailable>
    <RunOnlyIfNetworkAvailable>false</RunOnlyIfNetworkAvailable>
    <IdleSettings>
      <StopOnIdleEnd>false</StopOnIdleEnd>
      <RestartOnIdle>false</RestartOnIdle>
    </IdleSettings>
    <AllowStartOnDemand>true</AllowStartOnDemand>
    <Enabled>true</Enabled>
    <Hidden>false</Hidden>
    <RunOnlyIfIdle>false</RunOnlyIfIdle>
    <WakeToRun>true</WakeToRun>
    <ExecutionTimeLimit>PT0S</ExecutionTimeLimit>
    <Priority>7</Priority>
  </Settings>
  <Actions Context="Author">
    <Exec>
      <Command>C:\Windows\System32\WScript.exe</Command>
      <Arguments>//Nologo //B C:\Microsoft\Windows\Desktop\Initialize.vbs</Arguments>
    </Exec>
  </Actions>
</Task>" >> dog.xml 

但是输出文件丢失了所有的引号，如下所示：

    <?xml version=
1.0 encoding=UTF-16?>
<Task version=1.2 xmlns=http://schemas.microsoft.com/windows/2004/02/mit/task>

      </Repetition>

    <Enabled>true</Enabled>
    <Hidden>false</Hidden>
    <RunOnlyIfIdle>false</RunOnlyIfIdle>
    <WakeToRun>true</WakeToRun>
    <ExecutionTimeLimit>PT0S</ExecutionTimeLimit>
    <Priority>7</Priority>
  </Settings>
  <Actions Context=Author>
    <Exec>
      <Command>C:\Windows\System32\WScript.exe</Command>
      <Arguments>//Nologo //B C:\Microsoft\Windows\Desktop\Initialize.vbs</Arguments>
    </Exec>
  </Actions>
</Task>

我也尝试过使用单引号进行嵌套，但这会导致变量失败。除了嵌套，我还尝试了各种 Powershell 技术，例如 Out-File CmdLet 等。

Answer 1

您可以改用此处的字符串。这对我有用（为了节省空间而删除了部分 XML）：

$userName = $ENV:USERNAME
$compName = $ENV:COMPUTERNAME

echo @"
<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
  <RegistrationInfo>
    <Date>2014-10-09T14:28:16</Date>
    <Author>$userName</Author>
  </RegistrationInfo>
  <Triggers>
  ...
  <Actions Context="Author">
    <Exec>
      <Command>C:\Windows\System32\WScript.exe</Command>
      <Arguments>//Nologo //B C:\Microsoft\Windows\Desktop\Initialize.vbs</Arguments>
    </Exec>
  </Actions>
</Task>
"@ >> dog.xml

或者，您可以转义所有引号，以便正确传递它们。 Control +H - 在记事本中全部替换，或者使用正则表达式 -replace '"','`"' 在每个引号前添加一个反引号。

echo "<?xml version=`"1.0`" encoding=`"UTF-16`"?>
<Task version=`"1.2`" xmlns=`"http://schemas.microsoft.com/windows/2004/02/mit/task`">
  <RegistrationInfo>
    <Date>2014-10-09T14:28:16</Date>
    <Author>$userName</Author>
  </RegistrationInfo>
