Use xml.etree.ElementTree.iterparse for *very* large xml data
"""
iterparse(source, events=None, parser=None)
Incrementally parse XML document into ElementTree.
This class also reports what's going on to the user based on the
*events* it is initialized with. The supported events are the strings
"start", "end", "start-ns" and "end-ns" (the "ns" events are used to get
detailed namespace information). If *events* is omitted, only
"end" events are reported.
