event log - Python WINEVTLOG Open Backup Logs -

i attempting use openbackupeventlog("",file) open eventlogs saved on cdrom. going through loop load each file under subdirectory. have 2 issues @ moment.
1. script pull first file name , output events on screen, when reach end not reset. 2. when goes through second position of list gives error of file not found.

import win32evtlog  e = os.listdir('d:\\somedir\\anotherdir\\')  item in range(len(e)):     handle = win32evtlog.openbackupeventlog("none", e[item])     flags = win32evtlog.eventlog_backwards_read|win32evtlog.eventlog_sequential_read     total = e.getnumberofeventlogrecords(handle)     print "total events are: ", total      while true:         event_list = win32evtlog.readeventlog(handle, flags, 0)         if event_list:             event in event_list:             info = (event.eventtype,                     event.timegenerated,                     event.sourcename,                     event.eventid)             print info 

any appreciated; it's can't close connection on win32evtlog. have used win32evtlog.closeeventlog(handle).

few items causing issue:

1. cdrom or cd erroring out; have copy files temp directory , process them.
2. no break @ end of loop; if not event: break
