  - by Noam Smadja

  It doesnt find nor replaces the strings.. may be wrong regex? // ==UserScript== // @name CurConvertor // @namespace CurConvertor // @description noam smadja // @include http://www.zavvi.com/* // ==/UserScript== textNodes = document.evaluate( "//text()", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); var searchRE = new RegExp('\d\d.\d\d','gi'); var replace = searchRE*5.67; for (var i=0;i<textNodes.snapshotLength;i++) { var node = textNodes.snapshotItem(i); node.data = node.data.replace(searchRE, replace); i wrote this, but its not doing a think. even when i change the string in the regex to a string in the webpage it still does nothing.. what am i missing? :)

• Date and timezone using j2me

  - by joynes

  Hi everyone! I have a date string as input from an rss like: Wed, 23 Dec 2009 13:30:14 GMT I want to fetch only the time-part, but it should be correct according to the my timezone. Ie, in Sweden the output should be: 14:30:14 What is the best way? I want it to work with other RSS date formats as well if possible. Im using regexp right now but that is not very general. Im having a hard time finding any library or support for dates and timezones in j2me? /Br Johannes

• ASCIIMath and TiddlyWiki

  - by Space_C0wb0y

  I use TiddlyWiki for work-notes. I already have pretty large wiki, but now I want to add math-support. As far as I understand what is written here, all I would have to do to use ASCIIMathML in my wiki would be including the script ASCIIMathML.js. Doesn't work (no effect at all). Then I found this plugin for TiddlyWiki, but when I import it to my wiki, it gives me an error in one of the regexp strings. When I download that wiki directly, ASCIIMath does not work anymore, even though I have the script in the same directory. Does anyone have a solution available, how I can add ASCIIMath to my existing TiddlyWiki?

• How do you comment html templates in Php (in a practical way) ?

  - by faB

  Is there a simple solution to do the equivalent of Java's comments: <%-- this is a comment inside a template, it does not appear in the output HTML --%> Even if you use short php tags, you still have to wrap the comments with comment syntax, on top of the php tags: <? /* this is a comment of the html template */ ?> I'm considering doing some kind of filter on the output templates, to remove all html comments, or better yet, custom comments like the Java syntax above, but how would you do that in the most efficient way? You'd have to run a regexp right? The reason for my question is simply that in a MVC framrwork, using components, and re-usable html templates (think YUI), I need to document clearly those templates, in a readable way..

• VBScript + Regular Expressions

  - by Karthik

  Dim sString sString = "John;Mary;Anne;Adam;Bill;Ester" Is there a regex I can use to retrieve the following from the above list: John (; at the end of the name) Anne (; at the beginning and end) Ester (; at the beginning) I am currently using the following regex for each: 1. Joh.* 2. .*An.* 3. .*st.* But, the above retrieves the entire string instead of the values I want. How can I get the correct values? Code: Dim oRegex : Set oRegex = New RegExp oRegex.Global = False oRegex.IgnoreCase = False 'John oRegex.Pattern = "Joh.*" Set oMatch = oRegex.Execute(sString) sName = oMatch(0) The above code retrieves the entire string, instead of only John. Same issue with the others :(

• Strip tags (with tags inside attributes and nested tags) using javascript

  - by Kokizzu

  What the fastest (in performance) way to strip strings from tags, most solution i've tried that uses regexp not resulting correct values for tags inside attributes (yes, i know it's wrong), example test case: var str = "<div data-content='yo! press this: <br/> <button type=\"button\"><i class=\"glyphicon glyphicon-disk\"></i> Save</button>' data-title='<div>this one for tooltips <div>seriously</div></div>'> this is the real content<div> with another nested</div></div>" that should resulting: this is the real content with another nested

• pylint ignore by directory

  - by Ciantic

  Following is from pylint docs: --ignore=<file> Add <file or directory> to the black list. It should be a base name, not a path. You may set this option multiple times. [current: %default] Yet I'm not having luck getting the directory part work. I have directory called migrations, which has django-south migration files. As I enter --ignore=migrations it still keeps giving me the errors/warnings in files inside migrations directory. Could it be that --ignore is not working for directories? If I could even use regexp to match the ignored files it would work, since django-south files are all named 0001_something, 0002_something...

• Why Read In UTF-16LE File Won't Convert "\r\n" Into "\n" In Windows

  - by Dbger

  I am using Perl to read UTF-16LE files in Windows 7. If I read in an ascii file with following code: open CUR_FILE, "<", $asciiFile; Then each "\r\n" in file will be converted into a "\n" in memory; if I read in an UTF-16LE(windows 1200) file with following code: open CUR_FILE, "<:encoding(UTF-16LE)", $utf16leFile; Then "\r\n" will keep unchanged. This inconsistency cause problems when I trying to regexp lines with line breaks. My questions is: Is this how unicode works in Perl & Windows? Or Am I using the wrong code? Thanks so much!

• Racket regular-expression matching

  - by Inaimathi

  I'm trying to create a regex that matches the inverse of a certain string type (so, strings not ending in ".js", for example). According to the documentation, that should be the expression #rx"(?!\\.js$)", but it doesn't seem to work. To test it out, I have this function: (define (match-test regex) (map (lambda (text) (regexp-match? regex text)) '("foo.js" "bar.css" "baz.html" "mumble.gif" "foobar"))) (match-test #rx"\\.js$") returns (#t #f #f #f #f) as expected, but (match-test #rx"(?!\\.js$)") returns (#t #t #t #t #t), where I would expect (#f #t #t #t #t). What am I doing wrong, and how do I actually get a regex in Racket to express the idea "match anything which does not contain [x]"?

• Interpreting Search Results

  - by Simon

  Hi all, I am tasked with writing a program that, given a search term and the HTML source of a page representing search results of some unknown search engine (it can really be anything, a blog, a shop, Google, eBay, ...), needs to build a data structure of the results containing "what's in the results": a title for earch result, the "details" link, the position within the results etc. It is not known whether the results page contains any of the data at all, and whether there are any search results. The goal is to feed the data structure into another program that extracts meaning. What I am looking for is not BeautifulSoup or a RegExp but rather some clever ideas or algorithms on how to interpret the HTML source. What do I do to find out what part of the page constitutes a single result item? How do I filter the markup noise to extract the important bits? What would you do? Pointers to fields of research covering what I try to to are aly greatly appreciated. Thanks, Simon

• regex partial match for several different groups

  - by koral

  I need regexp to match string build from several groups (A is any letter, 9 is any digit): group 1 regex [A-Z]{1,2}[0-9]? A A9 AA9 group 2 regex [A-Z]{1,3}[0-9]? A AA AAA AAA9 group 3 regex [A-Z]{2,3}[0-9]?[A-Z]? AAA AA9 AA9A group 4 regex [0-9]{1,2}[A-Z]{1,2}[0-9]? 9A 9AA 9A9 99A9 Not each group must be present but there must be all in correct order - I mean (digit is group number): 1 12 123 1234 So if there is present group 3 there must me all preceding groups present also. As there are four groups (can be more), so alternative like ^[A-Z]{1,2}[0-9]{1}|[A-Z]{1,2}[0-9]{1}\s{1}[A-Z]{1}[0-9]?$ is not the best option as it would be complicated and difficult to maintain. Is there any solution with groups or something? The order of groups is important.

• Do any browsers yet support HTML5's checkValidity() method?

  - by James A. Rosen

  The HTML5 spec defines some very interesting validation components, including pattern (for validating against a Regexp) and required (for marking a field as required). As best I can tell, however, no browser yet actually does any validation based on these attributes. I found a comparison of HTML5 support across engines, but there is no information about validation there. In the browsers I've tried (Firefox 3.5.8 and Safari 4.0.4), no object has a checkValidity() method, so I can't run the validations even though I can define them. Is there any support for this feature out there so I can experiment?

• This regx does not work only in Chrome

  - by Deeptechtons

  Hi i just put up a validation function in jScript to validate filename in fileupload control[input type file]. The function seems to work fine in FF and sometimes in ie but never in Chrome. Basically the function tests if File name is atleast 1 char upto 25 characters long.Contains only valid characters,numbers [no spaces] and are of file types in the list. Could you throw some light on this function validate(Uploadelem) { var objRgx = new RegExp(/^[\w]{1,25}\.*\.(jpg|gif|png|jpeg|doc|docx|pdf|txt|rtf)$/); objRgx.ignoreCase = true; if (objRgx.test(Uploadelem.value)) { document.getElementById('moreUploadsLink').style.display = 'block'; } else { document.getElementById('moreUploadsLink').style.display = 'none'; } }

• Safest way to change variable names in a project

  - by kamziro

  So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

• Search object array for matching possible multiple values using different comparison operators

  - by Sparkles

  I have a function to search an array of objects for a matching value using the eq operator, like so: sub find { my ( $self, %params ) = @_; my @entries = @{ $self->{_entries} }; if ( $params{filename} ) { @entries = grep { $_->filename eq $params{filename} } @entries; } if ( $params{date} ) { @entries = grep { $_->date eq $params{date} } @entries; } if ( $params{title} ) { @entries = grep { $_->title eq $params{title} } @entries; } .... I wanted to also be able to pass in a qr quoted variable to use in the comparison instead but the only way I can think of separating the comparisons is using an if/else block, like so: if (lc ref($params{whatever}) eq 'regexp') { #use =~ } else { #use eq } Is there a shorter way of doing it? Because of reasons beyond my control I'm using Perl 5.8.8 so I can't use the smart match operator. TIA

• Parameters with dots on the URI

  - by robertokl

  In my application, there is a resource, machine, and a nested resource from machine: ip. I want to be able to access the URI of an Ip typing the ip address. The URI should be something like this: /machines/m123/ips/192.168.0.1.xml Where "m123" is the name of the machine and "192.168.0.1" is one of the ips of that machine. The problem here is that rails miss understand the dots from the ip and the format. When I try to access this page, i get: No route matches "/machines/m123/ips/192.168.0.1.xml" And if I replace the dots for any other character it works, witch means that rails isn't handling the dots on the URI. Is there any way to enter a more complex regexp on the routes to make sure rails can treat it the way I want? I'm using rails 2.3.5 and ruby 1.8.7. Thank you.

• Regular expression quantifier questions

  Hello, Im trying to find a regular expression that matches this kind of URL: http://sub.domain.com/selector/F/13/K/100546/sampletext/654654/K/sampletext_sampletext.html and dont match this: http://sub.domain.com/selector/F/13/K/10546/sampletext/5987/K/sample/K/101/sample_text.html only if the number of /K/ is minimum 1 and maximum 2 (something with a quantifier like {1,2}) Until this moment i have the following regexp: http://sub\.domain\.com/selector/F/[0-9]{1,2}/[a-z0-9_-]+/ Now i would need a hand to add any kind of condition like: Match this if in the text appears the /K/ from 1 to 2 times at most.

• How can I 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?

• Find folder name based on string value with batch

Basically I'm adding a line in a backup script to backup firefox bookmarks, but the profile name is going to be different on every machine and I need a way to find the folder the bookmarks.html file resides without knowing the firefox profile name I've looked at FIND and FINDSTR but neither seem to be what I need. I also looked at this post: http://stackoverflow.com/questions/2252785/windows-batch-file-get-folders-path-and-store-them-in-variable It was closer to what I'm looking for, but I just need a folder name, and to use something like regexp to find it Any suggestions on commands to look at or strategies to use?
