How relevant is the idea with xml + xsl today?

Question

ASP.NET

Hello everyone, I came here for a new job, there is a project with a database of suppliers. Each supplier has a large number of attributes with values, all of them are pulled out into xml, and then with the help of xls they are converted into html, which is already given to the client. This is how the tables for the page are formed.
Tell me, is it a common thing to work with data this way, or to some extent an outdated approach?
It is not very clear why the ViewModel is not used, into which the attributes are mapped, and then on pure Razor everything is driven into tags.
PS. Tomorrow, of course, I will ask the developers why this is so, but I would like to hear third-party thoughts.

Answer 1

In general, the situation is as follows:
there is a storage in the database, it forms xml, then with the help of xsl this business is translated into html. This piece of code is pulled from an old project, and, of course, I'm redoing it, since I asked: D
The conclusion is this: this is an old school, use ViewModel, ADO.net, and you will be happy!
