Anyone have an example of a custom inv script to pull a registry hive?

I am looking for a script that will pull a registry hive

example

HKLM\Software\MyKey

Where it has multiple value's and each value has some data

I want it to pull everythign in the hive into a custom data clasee

so that I will end up with my data class showing 2 colums and rows

so basically from looking at a reg export this is what I have and would want in the database where mykey is the class

I see examples of pulling just 1 registry key or targetted, but the values in this reg key vary and could be 10 per machine or 100 per machine.
