This would be nmy advice too, but you need to get an explicit iterator to 
use it.

it = open(.....)
for line in it:
    if 'NEW' in line:
        ln = it.next()

etc...

I prefer the next() approach.

But a third option is to use a split and apply it to the whole file as
a string thereby breaking the file into as many chunks as start with
a line containing 'NEW'...

data = open(....).read()
for chunk in data.split('NEW'):
     for line in chunk.split('\n'):  # create lines out of the chunks - you 
may not need this
          # process lines till done

Just a thought.
