Removing child node when a namespace is used

Hello everyone,

I'm trying to delete a single XML Element using powershell for an Excel.officeUI file but I'm having trouble getting it to identify the correct node.

The element looks like this:

<mso:tab id="mso_c2.3ED4DC" label="Macros" insertBeforeQ="mso:TabHome">.... and all the information about the custom ribbon I created in Excel appear all the way to </mso:tab>

It's nested in the following location:

<customUI>

<ribbon>

<tabs>

<mso:tab id="mso_c2.3ED4DC" label="Macros" insertBeforeQ="mso:TabHome">.... and all the information about the custom ribbon I created in Excel appear all the way to </mso:tab>

</tabs></ribbon</customUI>

There are other mso:tab element s with different ids but when I try the following code, it's giving me an error "the node to be removed is not a child of this node".

[xml]$xmlExcelLocal = Get-Content($localExcelFile)

$CopyMSONode = $xmlExcelLocal.ImportNode($xmlExcelNet.customUI.ribbon.tabs.tab,$true)

$xmlExcelLocal.customUI.ribbon.tabs.ParentNode.RemoveChild($CopyMSONode)
$xmlExcelLocal.Save($localExcelFile)

I've also tried:

$RemoveMSONode = $xmlExcelLocal.customUI.ribbon.tabs.SelectNodes('//mso:tab[@id="mso_c2.3ED4DC"]')

$xmlExcelLocal.customUI.ribbon.tabs.ParentNode.RemoveChild($RemoveMSONode)
$xmlExcelLocal.Save($localExcelFile)

Hopefully this makes sense to someone!

Thank you :)

Alex
