SNMP: Using sysdescr for Model/Manufacture determination (via regex)

At meraki hardware, a lot of informations (model, manufacture) exist in sysdescr. Is there any way to "filter" these informations to set manufacturer and model? (seems FI didn't read them out of the SNMP).

Examples:

Meraki MS350-24X Cloud Managed PoE Switch

Meraki MR53 Cloud Managed AP
