Thank you very much for this hint.

However, I am not just copying row-type elements from the input file, 
but rather summing up the values found in the "quantity" children of the 
entries, after grouping them by the content of "property1" and 
"property2" (see the first message in this thread).

I wonder how I could perform this task using the above approach.
