Automation Rule that Parses Through Ticket Description

Would there be a way to create an automation rule or email monitor rule that parses through ticket descriptions (email bodies) to obtain a specific number or string?

We are using an asset management platform that automatically sends emails to our monitored email address when devices are checked out to students. These emails come from a "no-reply" address, but we would like to set the requestor to the student receiving the device rather than the "no-reply". If we can parse the ID number from the email body, I am thinking that we can assign the tickets' requestor based on matching the ID number to the users' TDX username as listed in TDAdmin.

Thank you.
