How to compare dom models of two pages?

Question

Software testing

Let's say there is a page layout, the developer has integrated this layout into the site. Is there any tool to compare the dom models of the original layout and the layout after implementation? Comparing pages by content is not an option, of course, because. the content will vary in the same way as the tabs. I would like to check the location and presence of all the tags on the page.

A in unit tests, they check whether the template is loaded at a certain URL.
You can also compare what gives the URL and what gives the view with the same parameters
