How to test the values of an XML file against a list of expected values?

I am testing an API for a website. I wrote a Selenium Webdriver script to change all of the fields for customer 1001 in the website UI.

When I make a call to the API, it exports a list of customers in an XML file.

Is there any tool I can use to automate the process of verifying that the values for customer 1001 in the XML file match the set of values that should now be assigned to the fields?

I want to automate this because I am going to be testing multiple APIs on an ongoing basis.
