[lxml] Streaming read/write

Hiya, I was recently wondering about the best way to edit XML documents using both a streaming reader and writer. I'm sure this is possible using iterparse and xmlfile but I seem to remember that iterparse produces the full tree so that parent elements and their children are returned. Has anyone had any experience with this?
