Copy XML file and strip off certain elements

I have a XML file that I would like to copy to another location e.g. Folder, Directory.

Then when it's been copied, I need the copied version updated with certain elements removed.

I've attached two files the original that is to be copied and the copied with the elements removed.

Basically, if you look at the original file it has elements that have a BI, RS or IM preceded by an under score.

I need all those elements removed from the file.

So the new file would look like the one I attached to this EE question.

Not sure if this would be easier to do with Windows Batch or VB script.

Thanks

Batch:
findstr.exe /v /r "<[A-Z0-9]_BI <[A-Z0-9]_RS <[A-Z0-9]_IM" "C:\Temp\Today.xml" >"C:\Temp\Today_Copied.xml"

Edit: made the RegEx more robust.

Correction for the edited version, sorry:
findstr.exe /v /r "[A-Z0-9]_BI [A-Z0-9]_RS [A-Z0-9]_IM" "C:\Temp\Today.xml" >"C:\Temp\Today_Copied.xml"

And maybe another note: the above only works because the xml source has the nodes you want filtered out on separate, single lines, without inner text or elements.
To treat the file as XML using Powershell:
[xml]$xml = Get-Content -Path "C:\Temp\Today.xml"
$xml.MSR.Info.SelectNodes('*') | % {If ($_.Name -match '\S+_(BI|RS|IM)\Z') {[void]$xml.MSR.Info.RemoveChild($_)}}
$Xml.Save("C:\Temp\Today_Copied.xml")
