选择Xml$offendingnode = select-xml -xpath "/DocIcons/ByExtension/Mapping[@Key='pdf']" -xml $xmldoc
$xmldoc | select-xml -xpath "/DocIcons/ByExtension" | % {$_.node.removechild($offendingnode.node)}
第一次编辑 你打算做什么还不是很清楚。而且你正在跑步的东西也有点乱 这一行：
$xml | Select-Xml -XPath '//Mapping' | ForEach-Object{$_.Node.RemoveAll()}
映射的所有子项。如果要删除ByExtension
下的所有映射
，则需要
$xml | Select-Xml -XPath '//ByExtension' | % {$_.Node.RemoveAll()}
要打印结果，请使用以下选项：
$xml.outerxml
您可以编辑并放置您的xml文件或与共享它吗
