Python Calendar Parsing Solution for Google Calendar

Question

I am trying to analyze the repetition field of GCal. Usually it looks like this:

DTSTART;TZID=Europe/Kiev:20101111T140000
DTEND;TZID=Europe/Kiev:20101111T150000
RRULE:FREQ=DAILY;UNTIL=20101112T120000Z
BEGIN:VTIMEZONE
TZID:Europe/Kiev
X-LIC-LOCATION:Europe/Kiev
BEGIN:DAYLIGHT
TZOFFSETFROM:+0200
TZOFFSETTO:+0300
TZNAME:EEST
DTSTART:19700329T030000
RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=-1SU
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:+0300
TZOFFSETTO:+0200
TZNAME:EET
DTSTART:19701025T040000
RRULE:FREQ=YEARLY;BYMONTH=10;BYDAY=-1SU
END:STANDARD
END:VTIMEZONE

I need to extract a part that is valuable to me: the DTSTART, DTEND, RRULE events and another iCaledar field. Is there an existing solution for this?
