Question

I am trying to read a zipped file in python. I want to read only files with “debug” in their names and only print lines which have BROKER_LOGON in them. It somehow does not read line by line, but prints the entire file which has BROKER_LOGON in it. Please tell me if there is a way to read line by line from a zipped file.

import os

import zipfile

import re

def main():
try:
    root = zipfile.ZipFile("C:/Documents and Settings/Desktop/20110526-1708-server.zip", "r")
except:
    root = "."  
for name in root.namelist():
    i = name.find("debug")
    if i>0:
        line = root.read(name).find("BROKER_LOGON")
        if line >0:
            print line


if __name__== "__main__":
    main()

Answer 1

for name in root.namelist():
    if name.find("debug") >= 0:
        for line in root.read(name).split("\n"):
            if line.find("BROKER_LOGON") >= 0:
                print line

This code reads the raw file contents with root.read(name), splits them to lines and then scans the lines.
