• Exact match in regex character sets

  - by Dominik

  Hi all Consider the following string '35=_-235-b-35=35-35=2-135=a-35=123-235=2-35=a-53=1-53=a-553=b' I'd like to extract everything that matches 35= followed by 1 or 2 characters. What I came up with is the following regex \d[35]=[A-Za-z0-9]{1,2} The problem is the character set [35] matches both 35= and 53=. How can I achieve an exact match for a character set? Any suggestions, or different approaches are very much appreciated!

  - by Ben

  I have an html document with multiple commented-out PHP arrays, e.g.: <!-- Array ( [key] => 0 ) --> Using PHP, I need to somehow parse the HTML for only these comments (there are other comments that will need to be ignored) and extract the contents. I've been trying to use preg_match_all but my regex skills aren't up to much. Could anyone point me in the right direction? Any help is much appreciated!

• Regex: Matching against groups in different order without repeating the group

  - by Jimmy

  Let's say I have two strings like this: XABY XBAY A simple regex that matches both would go like this: X(AB|BA)Y However, I have a case where A and B are complicated strings, and I'm looking for a way to avoid having to specify each of them twice (on each side of the |). Is there a way to do this (that presumably is simpler than having to specify them twice)? Thanks

• Looking for regex to extract email addresses from /etc/passwd

  - by Brent

  Most of my users have email addresses associated with their profile in /etc/passwd. They are always in the 5th field, which I can grab, but they appear at different places within a comma-separated list in the 5th field. Can somebody give me a regex to grab just the email address (delimeted by commas) from a line in this file? (I will be using grep and sed from a bash script) Sample lines from file: user1:x:1147:5005:User One,Department,,,[email protected]:/home/directory:/bin/bash user2:x:1148:5002:User Two,Department2,[email protected],:/home/directory:/bin/bash

• Help with regex - extracting text.

  - by Yeti

  I have 3 separate strings: $d = 'Created on November 25, 2009'; $v = 'Viewed 17,603 times'; $h = '389 hits'; Which needs to be converted to: $d1 = {unix timestamp of November 25, 2009}; $v1 = "17603"; (commas stripped if it exists) $h1 = "389"; What is the most efficient way to do this (possibly with regex)?

• Using a regex to match IP addresses in Python

  - by MHibbin

  I'm trying to make a test for checking whether a sys.argv input matches the regex for an IP address... As a simple test, I have the following... import re pat = re.compile("\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}") test = pat.match(hostIP) if test: print "Acceptable ip address" else: print "Unacceptable ip address" However when I pass random values into it, it returns "Acceptable ip address" in most cases, except when I have an "address" that is basically equivalent to \d+ Any thoughts welcome. Cheers Matt
