  • Validate HTML entities in JavaScript

    - by Eduard Luca
    I have a small JavaScript validation script that validates inputs based on Regex. I want to allow certain characters that are not exactly common (not sure if they're UTF8). For example I want to allow the following character ’, which looks like a single quote, but isn't. I got the HTML code for this which is &#8217;, but I'm not sure how to put this into the Regex. I've tried just inputting [&#8217]* but it doesn't validate.

    - by Melursus
    I got the following : 01.05.03 I need to convert that to 1.5.3 The problem is I cannot only trim the 0 because if I got : 01.05.10 I need to convert that to 1.5.10 So, what's the better way to solve that problem ? Regex ? If so, any regex example doing that ?

  • Ignoring certain chars globally

    - by shi kui
    Consider it that '_'s in a number doesn't change that number's value so 1000==1_000==10_00. The Problem: given numbers like 1_244_23 1412_2 1_1111 etc..., how could I decide whether certain number appears in that collection? For example: 1244_23 yes, 11_111 yes, 1412_1 no. How could using regex to solve this? I mean, if I could tell the regex engine just ignore these '_''s when matching then this problem becomes trivial? How could I do so?

  • Regular expression (PCRE) for url matching

    - by zerkms
    The input: we get some plain text as input string and we have to highlighight all urls there with {url For some time i've used regex taken from http://flanders.co.nz/2009/11/08/a-good-url-regular-expression-repost/, which i modified several times, but it's built for another issue - to check whether the whole input string is an url or no. So, what regex do you use in such issues?

    - by Scott
    I've hit a wall. Does anybody know a good text editor that has search and replace like Notepad++ but can also do multi-line regex search and replace? Basically, I am trying to find something that can match a regex like: search oldlog\(.*\n\s+([\r\n.]*)\);replace newlog\(\1\) Any ideas?

  • Javascript regular expressions: how to match ONLY the given characters?

    - by Dfowj
    I'm trying to use a regex like /[computer]{3,8}/ to get any words containing only the letters in computer ranging from 3 to 8 letters long.

How do i modifiy this regular expression to capture words containing ONLY the letters in computer (with a length of 3 to 8)?

  • Replace all URL unless it is allowed

    - by ratamaster
    I had a regex that replaced all URLs from a given string: my_string = "www.example.com test www.mysite.com" my_string.gsub!(/[a-zA-Z0-9\-\.]+\.(com|net|de|org|uk|biz|info|co.uk|es|de)(\/\S*)?/i,'(site hidden)') As a result of the above I get: "(site hidden) test (site hidden)" How could I change the regex to not replace www.mysite.com ??? It means that the replace should output "(site hidden) test www.mysite.com" Thanks !

  • Search files for text matching format of a Unix directory

    - by BrandonKowalski
    I am attempting to search through all the files in a directory for text matching the pattern of any arbitrary directory. The output of this I hope to use to make a list of all directories referenced in the files (this part I think I can figure out on my own). I have looked at various regex resources and made my own expression that seems to work in the browser based tool but not with grep in the command line. /\w+[(/\w+)]+ My understanding so far is the above expression will look for the beginning / of a directory then look for an indeterminate number of characters before looking for a repeating block of the same thing. Any guidance would be greatly appreciated.

  • nginx regex locations w/ different roots not working as expected

    - by Wells Oliver
    I have the following two rules: location / { root /var/www/default; } location ~* /myapp(.*)$ { root /home/me/myapp/www; try_files $uri $uri/ /handle.php?url=$uri&$args; } When I browse to myapp/foo it works- kind of, the error is logged as a 404: *3 open() "/var/www/default/handle.php" failed (2: No such file or directory) - so its handling the regex match but just not using the right document root-- why is this? For the record, I am trying to get /myapp/* requests handled by the second location, and everything else the first.

  • Match exactly (and only) the pattern I specify in a grep command

    - by palswim
    Usually, grep searches for all lines containing a match for the pattern/parameter I specify. I would like to match just the pattern (i.e. not the whole line). So, if a file contains the lines: We said that we'll come. Unfortunately, we were delayed. Now, we're on our way. I want to find all contractions starting with "we" (regex pattern: we\'[a-z]+/i). And I'm looking for the output: we'll we're How do I do this (with grep or another Unix/Windows command-line tool)?

  • Move all images in folder to subfolder, and update all references to those images to their new location?

    - by Professor Frink
    I have a folder which contains a ~50 text files (PHP) and hundreds of images. I would like to move all the images to a subfolder, and update the PHP files so any reference to those images point to the new subfolder. I know I can move all the images quite easily (mv *.jpg /image, mv *.gif /image, etc...), but don't know how to go about updating all the text files - I assume a Regex has to be created to match all the images in a file, and then somehow the new directory has to be appended to the image file name? Is this best done with a shell script? Any help is appreciated (Server is Linux/CentOs5) Thanks!

  • Select different parts of an line

    - by Ricardo Sa
    I'm new to regexes and have a file that looks like this one: |60|493,93|1,6500| |60|95,72|1,6500| |60|43,88|1,6500| |60|972,46|1,6500| I used the regex (\|60|.*)(1,65) and I was able to find all the lines that have the information that I wanted to changed. How can I make an replace that when Notepad++ finds (\|60|.*)(1,65), the 60 should be replaced with 50: |50|493,93|1,6500| |50|95,72|1,6500| |50|43,88|1,6500| |50|972,46|1,6500| PS: here's an example of the full line: |C170|002|34067||44,14000|KG|493,93|0|0|020|1102||288,11|12,00|34,57|0|0|0|0|||0|0|0|60|493,93|1,6500|||8,15|60|493,93|7,6000|||37,54||

  • htaccess filesMatch exclusion

    - by Hikari
    I have the following directive in my htaccess <filesMatch "\.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml|html?)$"> FileETag None <ifModule mod_headers.c> Header unset ETag Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" </ifModule> </filesMatch> I copied that regex from someplace in Web months ago. It should add those headers to any HTTP Response that does NOT have those extensions. But it's not working, it's adding them to any Response. I also need to create another directive to add Header set Cache-Control "max-age=3600, public" to Responses of files that DOES have them. Could anybody help me make proper fileMatch regexes?

  • Getting text between quotes using regular expression

    - by Camsoft
    I'm having some issues with a regular expression I'm creating. I need a regex to match against the following examples and then sub match on the first quoted string: Input strings ("Lorem ipsum dolor sit amet, consectetur adipiscing elit.") ('Lorem ipsum dolor sit amet, consectetur adipiscing elit. ') ('Lorem ipsum dolor sit amet, consectetur adipiscing elit. ', 'arg1', "arg2") Must sub match Lorem ipsum dolor sit amet, consectetur adipiscing elit. Regex so far: \((["'])([^"']+)\1,?.*\) The regex does a sub match on the text between the first set of quotes and returns the sub match displayed above. This is almost working perfectly, but the problem I have is that if the quoted string contains quotes in the text the sub match stops at the first instance, see below: Failing input strings ("Lorem ipsum dolor \"sit\" amet, consectetur adipiscing elit.") Only sub matches: Lorem ipsum dolor ("Lorem ipsum dolor 'sit' amet, consectetur adipiscing elit.") The entire match fails. Notes The input strings are actually php code function calls. I'm writing a script that will scan .php source files for a specific function and grab the text from the first parameter.

  • php regex word boundary matching in utf-8

    - by dontomaso
    Hi, I have the following php code in a utf-8 php file: var_dump(setlocale(LC_CTYPE, 'de_DE.utf8', 'German_Germany.utf-8', 'de_DE', 'german')); var_dump(mb_internal_encoding()); var_dump(mb_internal_encoding('utf-8')); var_dump(mb_internal_encoding()); var_dump(mb_regex_encoding()); var_dump(mb_regex_encoding('utf-8')); var_dump(mb_regex_encoding()); var_dump(preg_replace('/\bweiß\b/iu', 'weiss', 'weißbier')); I would like the last regex to replace only full words and not parts of words. On my windows computer, it returns: string 'German_Germany.1252' (length=19) string 'ISO-8859-1' (length=10) boolean true string 'UTF-8' (length=5) string 'EUC-JP' (length=6) boolean true string 'UTF-8' (length=5) string 'weißbier' (length=9) On the webserver (linux), I get: string(10) "de_DE.utf8" string(10) "ISO-8859-1" bool(true) string(5) "UTF-8" string(10) "ISO-8859-1" bool(true) string(5) "UTF-8" string(9) "weissbier" Thus, the regex works as I expected on windows but not on linux. So the main question is, how should I write my regex to only match at word boundaries? A secondary questions is how I can let windows know that I want to use utf-8 in my php application.
