I recommend looking at the stdlib xml.etree.ElementTree module or the
external lxml package (which contains the ElementTree compatible lxml.etree
module). The latter will (likely) make things easier due to full XPath
support and some other goodies, but E
ftware from unknown third-party sources may simply
not be a valid alternative in a given setting, e.g. on a company computer.

It's just a matter of understanding (or getting used to) the API. You might
