The regexp for the above could be:
reg = sre.compile(
r'''
(?P<name>
^[-\w]+ # name is the match in our string which can consist of
# nearly everything
(\.\D[-\w]+?)?) # if it contains a point it is followed by a non-digit char
# we search till we find
- # a hyphen
(?P<version>
\d+(\.\w+)*) # a version consists of digits and points
# we search till we find
- # a hyphen
(?P<release>
[\d.]+(EL)?) # release consists of digits seperated by a point and ends
# optionally with EL
\.(\w*\.)? # no comes a point and optionally a string
(?P<arch>
\w+?) # arch is the shortest everything between .rpm and the point
\.rpm$'''
, sre.X)
