$xmlFile = "D:\ServiceConfiguration.cscfg"
[xml]$doc = Get-Content $xmlFile
$node = $doc.SelectSingleNode("/ServiceConfiguration/Role/ConfigurationSettings[@name='DiagnosticsConnectionString']")
$node.value = "New-Value"
$doc.Save($xmlFile)
SelectSingleNode總是返回null。請幫助電源外殼腳本SelectSingleNode不工作
你的XPath是錯誤的或者有在cscfg文件中使用的命名空間。沒有輸入文件很難回答.. – stej 2011-04-12 11:59:21
