the doc does warn: 'You should also avoid moving or discarding the element itself.'

but the example does exactly what I do, which is to clear the element after the 'end' event. isn't the example contradicting the warning?

>>> for event, element in etree.iterparse(StringIO(xml)):
...     # ... do something with the element
...     element.clear()                 # clean up children
...     while element.getprevious() is not None:
...         del element.getparent()[0]  # clean up preceding siblings

This is a known limitation of the current implementation:
