Create a list of nested node attributes from an XML file

I have an XML file:

<?xml version="1.0" encoding="utf-8"?>
<files>
    <file name="1">
        <file name="4">     
        </file> 
    </file>
    <file name="2">
    </file>
    <file name="3">
        <file name="5">
            <file name="7">
            </file>
        </file>
    </file>
</files>

Now I want to create a list of strings / numbers that store the entire attribute namein a list / array with a hierarchy of nested nodes. For example, for the above XML file, the expected list is

(1,4
2
3,5,7)

Because I could know the desired node, at what level.

Could you tell me what you think about such a list?

Update: After Jon, answer, if the child nodes are in the same hierarchy, then it will be as follows.

XML file:

<files>
<file name="1">
    <file name="4"/>     
    <file name="2">
      <file name="3"/>
    </file> 
</file>
<file name="5"/>

and the desired result:

1,4
1,2
1,2,3
5

PS. After testing some examples, I noticed that I should have the first parent, and then the children, if there are two or more children from the same level.
