[Tutor] Removing Content from Lines....

[Dimitar Ivanov]

Hello everyone,

First time using the mailing list to give a suggestion, apologies in
advance if it's not appropriate :)

Considering you're looking for specific string, I'd recommend maybe looking
into the Regular Expressions. You could use something like:

#At the top of the file
import re

#Within your function
target = open(filename, 'rU')
# This will read the file as a whole string, careful, it loads the file
into memory so if it's a big file, it might cause troubles
text = target.read()
# The regular expression should match every single tag and its content
within the file, using '.*?' will match each character without being greedy.
match = re.findall(r'<uicontrol>.*?<uicontrol>', text)

Afterwards, you can use something like:

for i in match:
  print i

This should print out all the matches to Stdout so you can verify the RegEx
behaves as expected. To write the matches in a new file, you could do:
  new = open('Matches', 'w') ## This will create a new file called
'Matches' for writing
  for i in match:
    new.write(i + '\n') ## Each match of the RegEx will be written on a new
line in the Matches file.

At the end, my function looks like this:

def textfind(filename):
  target = open(filename, 'rU')
  text = target.read()
  match = re.findall(r'<uicontrol>.*?</uicontrol>', text)
  new = open('Matches', 'w')
  for i in match:
    new.write(i + '\n')

Dimitar
