Querying SCCM for Collection rules by Powershell

Question

I am trying to get a list of collections rules applied to a particular collection, in sccm. I have psbase property of a collectionrules which contains the names of the collectionrules. How do I access those collections, using powershell?

Answer 1

A collection can have multiple query-based membership rules.  Each of those rules can have multiple queries.  CSVs are 2 dimensional, and don't support this type of nesting.  You could simply take the first query from the first rule, but depending
on how the collections are defined, there could be missing information.
XML on the other hand, can support this type of nesting.
I haven't tested this (use at your own risk), but this could be the general idea, if you wanted to move queries from one system to another, or simply back them up.
#Backup Collection Data from source computer
Get-CMDeviceCollection | Export-Clixml 'c:\OldComputer\AllCollections.xml'
#Restore to target computer (This sets the limiting collection to "All Systems" and also assumes there is only one membership rule)
$allCollections = Import-Clixml 'c:\NewComputer\AllCollections.xml'
$allCollections | ? {$_.isbuiltin -eq $false} | % {
New-CMDeviceCollection -LimitingCollectionId SMS00001 -Name $_.Name
Add-CMDeviceCollectionQueryMembershipRule -CollectionName $_.Name -RuleName $_.CollectionRules.RuleName -QueryExpression $_.CollectionRules.QueryExpression
