Besides, that is sortable (unlike strings where 15 < 2) : latest minor for major : major, max(minor) where major = what you want <pgversion><major><int value="8" /><int value="2" /></major><minor><int value="3" /></minor></pgversion> from BeautifulSoup import BeautifulSoup as Soup s = Soup("""<pgversion><major><int value="8" /><int value="2" /></major><minor><int value="3" /></minor></pgversion>""" ) >>> v = s.find('pgversion') >>> [int(x['value']) for x in v.find('major') ] [8, 2] >>> [int(x['value']) for x in v.find('minor') ] [3]
