How to make a tree in the form of drop-down lists from XML?

Question

PHP

Good day to all)
There is a task, I think from which side to approach it. Maybe you can recommend something to read or give examples to look at.
Task:
* Process xml file.
* Generate a tree in the form of drop-down lists ().
* The result should be: step by step selection of a value from the list at each nesting level.
* That is, you need to go from the choice of resolution (this is the film thickness) to the choice of post-processing values
​​* At the first step, the choice of resolution, after selection, a list appears with material options for this resolution,
* Select the material - PostProcessing options related to it appear (all available for this material)
* and value choices for each of PostProcessing. That is, the choice of PostProcessingValue is available after selecting the material and is grouped by PostProcessing
. As far as I understand, there should be a form of type select when hovering over which one more drop-down menu appeared. I think it is necessary to use php with the SimpleXML or DOM library, xml must be processed by xlst. Do I need to use javascript here, or can I do without it? I didn’t google something very similar, except perhaps https://habrahabr.ru/post/65077/
Here is the beginning of the xml file (it is long, but of the same type):
