It would help volunteers if you could post a contrived example of the 
nature of the structures.  Not all 50 levels, but still, some examples.

How are you expressing the "someStr" name?  Is it fixed?  Is it variable?

You will probably not use "//" as you have above, but it may have a 
role in the solution.

So you want one of every depth?  Is it always the same element name 
that is parent/child?

Ummmmm ... I make that 5000 queries.  Or 100 queries that each give 50 results.

>Is is posible to write iteration in XQuery for that. Or pass it as a function?

Probably with two passes where the first pass creates the query for 
the second pass to execute.

But it would help to have some representative data and an example 
result for that data.
