如何使用PowerShell刪除XML節點？

我在努力找到一種方法來刪除此節點：如何使用PowerShell刪除XML節點？

<Mapping Key="pdf" Value="icpdf.gif"/>

我列出了XML文件，在該線程的底部。

這是我到目前爲止。

這是我運行：

$xmlFile = 「C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\XML\docicon.xml」 
$xmlDoc = [XML](gc $xmlFile) 
$xml =[xml]'<DocIcons><ByExtension><Mapping Key ="pdf" Value = "icpdf"/></ByExtension></DocIcons>' 
$xml | Select-Xml -XPath '//Mapping' | ForEach-Object{$_.Node.RemoveAll()} 
$xmldoc.save("C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\XML\docicon.xml") 
$xml

任何幫助，不勝感激:-)

DocIcon.xml的：有問題的節點是正確的接近尾聲

您可以編輯，並把你的xml文件或[控釋片分享]（https://gist.github.com/） – JPBlanc 2011-05-26 11:58:15

如果我沒有錯，你想刪除冒犯的節點從您的輸入文件。這個，如果你想使用Select-Xml你可以做什麼：

$offendingnode = select-xml -xpath "/DocIcons/ByExtension/Mapping[@Key='pdf']" -xml $xmldoc 
$xmldoc | select-xml -xpath "/DocIcons/ByExtension" | % {$_.node.removechild($offendingnode.node)}

1日編輯

這不是很清楚你打算做什麼。另外你正在運行的是一點搞砸。

這一行：

$xml | Select-Xml -XPath '//Mapping' | ForEach-Object{$_.Node.RemoveAll()}

你要刪除的mapping所有兒童。如果你想刪除ByExtension下的所有mapping你需要像

$xml | Select-Xml -XPath '//ByExtension' | % {$_.Node.RemoveAll()}

要打印的結果是更好，如果你使用：

$xml.outerxml
