Ohai node & multiple entries

Hello everyone,
First i’m glad to post my first question in here.
I want to appologies for each fault that could make… my writting english is not that good :confused:

Here is the subject:

I have a question about node with ohai.
As a matter of fact i want to obtain every mounting volumes name, to do so i must do node[‘filesystem’][‘Files-type’][‘mount’] for each différents files types.
Can i put an regular expression in my node like node[‘filesystem’][’*’][‘mount’] or obtain EACH volumes name with an other command ?

Thanks for reading me, hope that someone will have an answer, even negative one.
