[Tutor] formatting xml (again)

[richard kappler]

I was actually working somewhat in that direction while I waited. I had in
mind to use something along the lines of:


stx = '\x02'
etx = '\x03'
line1 = ""

with open('original.log', 'r') as f1:
   with open('new.log', 'w') as f2:
        for line in f1:
            if stx in line:
                line1 = line1 + line
            if not stx in line:
                if not etx in line:
                    line1 = line1 + line
            if etx in line:
                line1 = line1 + line + '\n'
                f2.write(line1)
                line1 = ""


but that didn't work. It neither broke each line on etx (multiple events
with stx and etx on one line) nor did it concatenate the multi-line events.
