Try lxml.etree. It's an extended re-implementation of ElementTree based on
libxml2. Amongst tons of other features, it provides its Elements with a
getparent() method and allows you to iterate over their ancestors (and other
XPath axes), or to iterate over a parsed document in an iterparse-like fashion
(called iterwalk).
