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.

Let's break this down at the pipes and look at each section;
