XPATH Pull First and Last name from multiple root element - xpath

Question

Getting a pull from a Saas API that sends unformatted XML. Need to pull the first and last names out of each element to send to another application.
I haev tried numerous things in Power Automate but they all error out due to the XML not having a parent node.
