So here it is....it might not be pretty (it seems a bit un-python like
to me) but it works exactly as required. If anyone can give any tips for
possible optimisation or refactor I would be delighted to hear from
them.
Thanks

I usually solve problems like this by pulling multiple lines from the
file within the loop. Something like this:
f = open('...ChangeLog.txt')
try:
while True:
line = f.next()
if line.startswith('----'):
line1 = line
line2 = f.next()
line3 = f.next()
line4 = f.next()
# Do something to process the lines
line = f.next()
except StopIteration:
pass
The basic idea is that you can collect multiple lines by calling
f.next() explicitly inside the loop.
