Comment puis-je supprimer un nœud XML à l'aide de PowerShell?

J'ai du mal à trouver un moyen de supprimer ce nœud:

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

J'ai énuméré le fichier XML au bas de ce fil.

C'est ce que j'ai obtenu jusqu'à présent.

C'est ce que je suis en cours d'exécution:

$xmlFile = “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions2\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\TEMPLATE\XML\docicon.xml") 
$xml

Toute aide grandement appréciée 🙂

docicon.xml: la délinquance nœud est tout près de la fin

Si je ne me trompe pas, vous voulez supprimer la offendingnode à partir de votre document d'entrée. Ce que vous pouvez faire si vous souhaitez utiliser Select-Xml:
```
$offendingnode = select-xml -xpath "/DocIcons/ByExtension/Mapping[@Key='pdf']"  -xml $xmldoc
$xmldoc | select-xml -xpath "/DocIcons/ByExtension" | % {$_.node.removechild($offendingnode.node)}
```
1ère édition

C'est pas très clair ce que vous allez faire. Aussi ce que vous êtes en cours d'exécution est peu foiré.

Avec cette ligne:
```
 $xml | Select-Xml -XPath '//Mapping' | ForEach-Object{$_.Node.RemoveAll()}
```
Vous allez supprimer tous les enfants de mapping. Si vous souhaitez supprimer toutes les mapping sous ByExtension vous besoin de quelque chose comme
```
 $xml |  Select-Xml -XPath '//ByExtension' | % {$_.Node.RemoveAll()}
```
Pour imprimer le résultat est meilleur si vous l'utilisez:
```
 $xml.outerxml
```
