Create a dictionary mapping the properties to their values, then print
out the ones you require:

fid = open('xxx', 'r')
lines = fid.readlines()
fid.close()

i = 0
items = {}
for line in lines:
    line = line.strip()
    if line[-1] == ':':
        line = line.split(':')[0]
        items[line] = lines[i+1].strip()
    i = i + 1
outString = '(' +  items.get('objStartId') + ',' +
items.get('eventName') + ',' + items.get('eventCond') + ',' +
items.get('eventAction') + ',' + items.get('objEndId') + ')\n'

print outString



This code yields the following output:

(14,trigger,guard,do_action,15)
