Here's a trimmed down version of how I did this (using ElementTree standalone,

This is from a class definition and the _elem attribute is a link to an
ElementTree.Element object.

def _add_elem(self, tagName, text, attrib ={}):
"""_add_elem(tagName, text, attrib={})
Adds a child element in the appropriate place in the tree.
Raises an IndexError if the checker does not allow an addition child
of tagName.
"""
last_child = None
for child in self._elem.findall('.//%s' % tagName):
last_child = child
if last_child is None:
new_child = ET.SubElement(self._elem, tagName, attrib)
else:
new_child = ET.Element(tagName, attrib)
self._elem.insert(self._elem._children.index(last_child)+1,
new_child)
new_child.text=str(text)
return new_child
I don't think you need to count the instances of the bingo node (unless you
want to prevent too many from being added in).

Thanks Josh. It looks like lxml adds some incredibly useful extensions
to ElementTree that I will use. See Stephan's reply.
