I'd like to flatten an lxml etree (specifically, HTML, if it matters.) How would I go about getting a flat list of all elements in the tree?

You can use the .iter() method, like so:
from lxml import etree
xml = etree.XML('''<html><body>
<p>hi there</p><p>2nd paragraph</p>
</body></html>''')
# If you want to visit all of the descendants
for element in xml.iter():
print element.tag
# Or, if you want to have a list of all the descendents
all_elements = list(xml.iter())
print [element.tag for element in all_elements]
