我喜欢将 Powershell 脚本与 Xml Linq 一起使用

using assembly System.Xml.Linq 

$filename = 'c:\temp\test.xml'

$doc = [System.Xml.Linq.XDocument]::Load($filename)

$variables = $doc.Descendants('Variable')

$lc_f_dpn = @([System.Linq.Enumerable]::Where($variables,  [Func[object,boolean]]{ param($x) $x[0].Attribute('Name').Value -eq 'LC_F_DPN'}))
$path = $lc_f_dpn[0].Element('Path').value
$path
