'''
Return all contents of an xml tree, without the outside tags.
e.g. if node is parse of
"<html a="b" foo="bar">Hi <div>there <span>Bruce</span><b>!</b></div><html>"
should return
"Hi <div>there <span>Bruce</span><b>!</b></div>"

# Useful things to know:
# node.tostring() -- generates xml for the node, including start
# and end tags. We'll use this for the children.
# node.text -- the text after the end of a start tag to the start
# of the first child
# node.tail -- the text after the end this tag to the start of the
# next element.
parts = [node.text]
for c in node.getchildren():
parts.append(etree.tostring(c, with_tail=True, encoding='unicode'))
# filter removes possible Nones in texts and tails
