  • 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!

  • Regex to match all of a set except certain ones

    - by Davy8
    I'm sure this has been asked before, but I can't seem to find it (or know the proper wording to search for) Basically I want a regex that matches all non-alphanumeric except hyphens. So basically match \W+ except exclude '-' I'm not sure how to exclude specific ones from a premade set.

  • Match Regex across newlines?

    - by Jörg Battermann
    I have a regex ( "(&lt;lof&lt;).*?(&gt;&gt;)" ) that works and matches perfectly on single line input. However, if the input contains newlines between the two () parts it does not match at all. What's the best way to ignore any newlines at all in that case?

  • Regex to match card code input

    - by kate
    How can I write a regex to match strings following these rules? 1 letter followed by 4 letters or numbers, then 5 letters or numbers, then 3 letters or numbers followed by a number and one of the following signs: ! & @ ? I need to allow input as a 15-character string or as 3 groups of 5 chars separated by one space. I'm implementing this in JavaScript.

  • 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

  • Look for match in a nested list in Python

    - by elfuego1
    Hello everybody, I have two nested lists of different sizes: A = [[1, 7, 3, 5], [5, 5, 14, 10]] B = [[1, 17, 3, 5], [1487, 34, 14, 74], [1487, 34, 3, 87], [141, 25, 14, 10]] I'd like to gather all nested lists from list B if A[2:4] == B[2:4] and put it into list L: L = [[1, 17, 3, 5], [141, 25, 14, 10]] Additionally if the match occurs then I want to change last element of sublist B into first element of sublist A so the final solution would look like this: L1 = [[1, 17, 3, 1], [141, 25, 14, 5]]

  • How can I match a match a null byte (0x00) in the Visual Studio binary editor with a find using a re

    - by Paul K
    Open a file in the Visual Studio binary editor that contains a null byte (0x00), then use the Quick Find feature (Ctrl +F) to find null bytes. I would have thought I could use a regular expression such as \x00 to match null bytes but it doesn't work. Searching for any other hex value using this method works fine. Is this a VS bug, 'feature', or am I just missing something? Is there a work around?

  • Regular Expression to match IP address + wildcard

    - by Ed Woodcock
    Hey guys I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system. I'm using the following Regex: "([0-9]{1,3}\\.|\\*\\.){3}([0-9]{1,3}|\\*){1}" Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator. Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ? Cheers, Ed

  • How to match 2 columns in excel?

    - by abhijithln
    Hi, I have an excel sheet, sheet1 which has 2 cols, A and B. Col A has some values and has corresponding mapping in col B(not all values in A have a mapping in B, some are empty). The sorting is done from Z-A and w.r.to Col A. I have another excel sheet, sheet2 which has similar Col A and Col B. Now, i want to find out whether any match is there between Col A of sheet1 and Col A of sheet2. If matches are found, those values should be copied onto a new column.

  • check all values match using prototype

    - by snaken
    Using prototype, is there a simple method of checking that a group of values match, for example - can this code be refined to a single line or something otherwise more elegant? var val = ''; var fail = false; $('form').select('.class').each(function(e){ if(!val){ val = $F(e); }else{ if(val != $F(e)) fail = true; } });
