需要幫助的更新（窗戶的unattend.xml）使用PowerShell XML文件

Question

這是我的XML文件：我寧願讀XML，然後修改計算機名說newcompname並把它寫回文件

Answer 1

您可以使用各種技術，像以下示例一樣迭代節點，使用XPATH查詢調用select-xml以查找節點，然後更改值或$ xml.selectNodes（...）。通常我會去的XPath的路線，但包括名稱空間，它是簡單的XML這是證明它在PowerShell中

$xml = [xml]@" 
    <?xml version="1.0" encoding="utf-8"?> 
    <unattend xmlns="urn:schemas-microsoft-com:unattend"># 
     <servicing></servicing> 
     <settings pass="specialize"> 
      <component name="Microsoft-Windows-Shell-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

      </component> 
    </settings> 
    </unattend> 
"@ 

#presuming multiple settings tags, with multiplecomponents 
$xml.unattend | foreach { $_.settings } | foreach { $_.component.computername = "newname" } 
$xml.save("c:\temp\test.xml")
