My 0.02$ There are some examples of using lxml in my repository:
https://github.com/czterybity/PyBasicTraining but AFAIR lxml can be tricky to install in some configurations (especially on windows). +1 for BeautifulSoup - easy and elegant, but still not in included batteries. Using standard library to get data from xml is quite easy (and efficient) if you use xml.sax instead of ElementTree or DOM. Good luck, Leszek --- dr inż.
