Standard way to generate / write XML files

Question

For a project, I need to generate XML files that adhere to a specific format. I was wondering what is the standard way to do this?

For my part, I use lxmland then write XML files. To do this, I wrote a small script that takes XML data as input, and then generates files.

Is this way to do it "OK"? Because I'm new to all of this, and I saw how many people use TeX and then convert it to XML.

Or is it better to do it at all?

EDIT: Please note that I must allow the end user to create these files without any effort required from them.
