Powershell regex match beginning

I am trying to get all registry keys beginning with a digit 1-9. This is what I am working with:

Get-ChildItem -Path HKLM:\SOFTWARE\Policies\Citrix | Where-Object {$_.name -Match '^[1-9]'}

Simple huh? Should work? Doesn't work! What am I missing?

Update1:

$CitrixPolRegDel = (Get-ChildItem -Path $CitrixPolRegPath).pschildName | Where-Object {$_ -Match '^[0-9]{1,2}$'}

This is what I am using now, pschildname turned out to be easier to use than the split example given below, but there might be drawbacks to this method that I am not aware of?

I also updated the regex expression to match regkeys named with one or two digits:

Regex retreives regkeys where name starts with (^) a digit 0-9 ([0-9]), digit in name can occur one to two times ({1,2}) and then the name should end ($)

So, the funny thing is that you run that GCI and it kicks back a table with the name of the sub keys and that's it, but if you do a Select -Expand Name it gives the full HKLM\Software\Policies\Citrix. So there's the problem, Name actually contains the full name of the key, not just the last sub-key.

So, you want the subkeys that start with 1-9? Split it out by \ and just use the last one for each entry. Try this out:

(Get-ChildItem -Path HKLM:\SOFTWARE\Policies\Citrix).Name | ForEach {$_.Split("\")[4] | Where-Object {$_.name -Match '^[1-9]'}}
