• How can match end-of-line multiple times in a regex without interpolation?

  - by harschware

  Hi, if I have a input with new lines in it like: [INFO] xyz [INFO] How can I pull out the xyz part? I tried a pattern like /^\[INFO\]$(.*?)$\[INFO\]/ms, but perl gives me: Use of uninitialized value $\ in regexp compilation at scripts\t.pl line 6. I've been trying things to get interpolation to stop like using qr// but alas, no love. EDIT: The key is that the end-of-line anchor is a dollar sign but at times it may be necessary to intersperse the end-of-line anchor through the pattern. If the pattern is interpolating then you might get problems such as uninitialized $\. For instance an acceptable solution here is /^\[INFO\]\s*^(.*?)\s*^\[INFO\]/ms but that does not solve the crux of the first problem. I've changed the anchors to be ^ so there is no interpolation going on, and with this input I'm free to do that. But what about when I really do want to reference EOL with $ in my pattern? How do I get the regex to compile?

• regex and javascript, some matches disappear !

  - by dader51

  Here is the code : > var reg = new RegExp(" hel.lo ", 'g'); > > var str = " helalo helblo helclo heldlo "; > > var mat = str.match(reg); > > alert(mat); It alerts "helalo, helclo", but i expect it to be "helalo, helblo, helclo, heldlo" . Only the half of them matches, I guess that's because of the space wich count only once. So I tried to double every space before processing, but in some case it's not enough. I'm looking for an explanation, and a solution. Thx

• jQuery Validation Engine with Mime

  - by Diego Pucci

  I have this custom rule with tje jQuery validation Engine: "validateMIME": { "func": function(field, rules, i, options){ var fileInput = field[0].files[0]; var MimeFilter = new RegExp(rules[3],'i'); if (fileInput) { return MimeFilter.test(fileInput.type); } else { return true;} }, "alertText": "* Estensione non supportata" }, The problem is that this is working ONLY if the field is required. But in my case the field is not required, but if filled then the Mime type needs to be checked. How do I edit this function to work with non required fields? what's wrong with it? Thanks

• How do I call functions of an object inside the same object?

  - by Roly

  I have the following Javascript code add_num = { f: function(html, num) { alert(this.page); }, page : function() { return parseInt(this.gup('page')); }, gup : function(name) { name = name.replace(/[\[]/,'\\\[').replace(/[\]]/,'\\\]'); var regex = new RegExp('[\\?&]'+name+'=([^&#]*)'); var results = regex.exec(window.location.href); if(results == null) return ''; else return results[1]; } } But when I call add_num.f() what I get from alert() is the actual code of page. That is, it returns function() { return parseInt(this.gup('page')); } I was expecting a numeric value and not any code at all.

• Get all email addresses in a string with JavaScript

  - by Mickel

  So, I have this JavaScript function: ME.Utils = { RxEmail: new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i), ValidateEmail: function(email) { return ME.Utils.RxEmail.test(email); }, GetEmailAddresses: function(text) { return text.match(ME.Utils.RxEmail); }, HasEmail: function(text) { return ME.Utils.GetEmailAddresses != null; } }; ValidateEmail works very well. However, HasEmail and GetEmailAddresses is not working properly. GetEmailAdresses always returns null, except for when the string only contains an email address. In this case, GetEmailAdresses returns an array not only containing the email address, but the email address ([email protected]), just the id (test) plus some unidentified etc. etc... Can you help me figure out what's wrong in my expression?

• When does ref($variable) return 'IO'?

  - by Zaid

  Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO'. Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to explain why: It isn't possible to create a true reference to an IO handle (filehandle or dirhandle) using the backslash operator. The most you can get is a reference to a typeglob, which is actually a complete symbol table entry [...] However, you can still use type globs and globrefs as though they were IO handles. In what circumstances would ref return 'IO' then?

• Flex 3 Regular Expression Problem

  - by Tommy

  I've written a url validator for a project I am working on. For my requirements it works great, except when the last part for the url goes longer than 22 characters it breaks. My expression: /((https?):\/\/)([^\s.]+.)+([^\s.]+)(:\d+\/\S+)/i It expects input that looks like "http(s)://hostname:port/location". When I give it the input: https://demo10:443/111112222233333444445 it works, but if I pass the input https://demo10:443/1111122222333334444455 it breaks. You can test it out easily at http://ryanswanson.com/regexp/#start. Oddly, I can't reproduce the problem with just the relevant (I would think) part /(:\d+\/\S+)/i. I can have as many characters after the required / and it works great. Any ideas or known bugs?

• js regex replace multiple words

  - by Raghav

  I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.

• How do I get query string value from script path?

  - by TruMan1

  I am adding my Javsacript file in pages with different query strings in the script path like this: Page1: <script type="text/javascript" src="file.js?abc=123"></script> Page2: <script type="text/javascript" src="file.js?abc=456"></script> Page3: <script type="text/javascript" src="file.js?abc=789"></script> In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work. In case it helps, below is a function I use to find the value of a query string param: function getQuerystring(key, defaultValue) { if (defaultValue == null) defaultValue = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.href); if (qs == null) return defaultValue; else return qs[1]; }

• How do I locate instances of <CR><LF><LF> in a mysql longtext field

  - by Ilane

  I would like to query my table for how many rows contain one or more instances of <CR><LF><LF>. I can't figure out the correct syntax. I would try LIKE '%<CR><LF><LF>%', but I don't know how to specify these special characters. I did try where mydata REGEXP '%[.CR.][.LF.][.LF.]%', and that didn't get a syntax error but neither did it return any rows. So, I realized I need a way to insert the test data as well! Note: I am using mysql 5.0.

• Switch statement for string matching in JavaScript

  - by yaya3

  How do I write a swtich for the following conditional? If the url contains "foo", then settings.base_url is "bar". The following is achieving the effect required but I've a feeling this would be more manageable in a switch: var doc_location = document.location.href; var url_strip = new RegExp("http:\/\/.*\/"); var base_url = url_strip.exec(doc_location) var base_url_string = base_url[0]; //BASE URL CASES // LOCAL if (base_url_string.indexOf('xxx.local') > -1) { settings = { "base_url" : "http://xxx.local/" }; } // DEV if (base_url_string.indexOf('xxx.dev.yyy.com') > -1) { settings = { "base_url" : "http://xxx.dev.yyy.com/xxx/" }; } Thanks

• Java file searching problem

  - by Infinity

  Hello guys! I need to search a file for a word and return the whole line and the line number with this word, then edit the line and write back to the file. Maybe the line number isn't necesary to edit a line in a file. I `was reading after seraching with regexp and opening the filechannel of the file, but I can't get the line number. Maybe there are other better ways to do this. Can you help me how to start this?

• Get ANSI-colored output from external command

  - by German Rumm

  I am writing a small script for watchr that runs my PHP unit tests. Current script runs tests using system() and displays them colored. I am trying to add libnotify functionality, but for that I need to parse the output and match against regexp, so that notification will either display green or red. system() doesn't return output, %x does return, but puts p doesn't display colors, which I need to quickly see which test failed. One option would be to run tests twice - once for display in terminal window, and second time for checking which notification to show, but I would rather avoid it.

• regex not working "within" javascript string

  - by Tim

  I'm trying to replace all mentions of [b] in a text string and replace it with <b>. The problem with what I'm using below this that it's replace every [b] on the page, and I only want it to change the [b]'s within the text string ("text") that I'm sending in. Taking out the 'g' for global in the regex doesn't work very well because it then doesn't replace them all... text = text.replace(new RegExp('(^|\\s|>)\\[b](\\S.*?\\S)\\[/b]($|\\s|<)', 'gim') , '$1<strong>$2</strong>$3'); any ideas? Thanks

• Jointure in linq with a regular expression

  - by Graveen

  I'm actually using a join in linqtosql (via dblinq). I'm trying to include a regular expression in the join part of the linq query. from i in collectiona join j in collectionb on Regex.IsMatch(i.name, j.jokered_name) equals true (...) I agree i can push the RegExp check in the where part of the linq query, but i was wondering if it is possible in the join part ? The above code wants an "i equals j" code structure. One thing i think to perform is overriding Equals() which 'll contains the RegEx.IsMatch() stuff and put a simple i equals j in the join part. Any suggestions about my problem ?

• Constructing a regular expression to wrap images with <a>

  - by bobo

  A web page contains lots of image elements: <img src="myImage.gif" width="180" height="18" /> But they may not be very well-formed, for example, the width or height attribute may be missing. And it also may not be properly closed with /. The src attribute is always there. I need a regular expression that wraps these with a hyperlink having href set to the src of the img. <a href="myImage.gif" target="_blank"><img src="myImage.gif" width="180" height="18" /></a> I can successfully locate the images using this regexp in this editor: http://gskinner.com/RegExr/: <img src="([^<]*)"[^<]*> But what is the next step?

• RegEx - character not before match

  - by danneth

  I understand the consepts of RegEx, but this is more or less the first time I've actually been trying to write some myself. As a part of a project, I'm attempting to parse out strings which match to a certain domain (actually an array of domains, but let's keep it simple). At first I started out with this: url.match('www.example.com') But I noticed I was also getting input like this: http://www.someothersite.com/page?ref=http://www.example.com These rows will ofcourse match for www.example.com but I wish to exclude them. So I was thinking along these lines: Only match rows that contain www.example.com, but not after a ? character. This is what I came up with: var reg = new RegExp("[^\\?]*" + url + "(\\.*)", "gi"); This does however not seem to work, any suggestions would be greatly appreciated as I fear I've used what little knowledge I yet possess in the matter.
