  • Ruby 1.9 regex as a hash key

    - by Liutauras
    I am trying this example myhash = {/(\d+)/ => "hello"} with ruby 1.9.2p136 (2010-12-25) [i386-mingw32]. It doesn't work as expected (edit: as it turned out it shouldn't work as I was expecting): irb(main):004:0> myhash = {/(\d+)/ => "hello"} => {/(\d+)/=>"Hello"} irb(main):005:0> myhash[2222] => nil irb(main):006:0> myhash["2222"] => nil In Rubular which is on ruby1.8.7 the regex works. What am I missing?

  • RegEx - Time Validation ((h)h:mm)

    - by Josh
    /^\d{1,2}[:][0-5][0-9]$/ is what I have. this limits minutes to 00-59. It does not, however, limit hours to between 0 and 12. For similarity and uniformity I would like to do this with RegEx alone if possible. Further-more I would like the first digit to be optional. i.e. 09:30 accepted as well as 9:30. I played around with ranges, but something out of range is always acceptable.

  • URL replacing regex

    - by perf
    I'm trying to make an url that adds a / to all hrefs and srcs in a string. It should only add a / to urls that don't have a http:// at their beginning and that don't have / yet also. If we have this: <a href="ABC">... <img src="DEFG">... <a href="/HIJ">... <a href="http://KLMN">... The results should be something like this: <a href="/ABC">... <img src="/DEFG">... <a href="/HIJ">... <a href="http://KLMN">... This is what i've come up till now: &(href|src)="?!(\/|http::\/\/)(.+)" And the replace would be $1="/$2" It isn't working, though. What am I doing wrong? How would the working regex have to look like

  • Looking for another regex explanation

    - by Sam
    In my regex expression, I was trying to match a password between 8 and 16 character, with at least 2 of each of the following: lowercase letters, capital letters, and digits. In my expression I have: ^((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,16})$ But I don't understand why it wouldn't work like this: ^((?=\d)(?=[a-z])(?=[A-Z])(?=\d)(?=[a-z])(?=[A-Z]){8,16})$ Doesnt ".*" just meant "zero or more of any character"? So why would I need that if I'm just checking for specific conditions? And why did I need the period before the curly braces defining the limit of the password? And one more thing, I don't understand what it means to "not consume any of the string" in reference to "?=".

  • HTML/CSS - How can I position these nested unordered lists correctly?

    - by Samuroid
    I am looking for some help resolving an issue im having with positioning the following unordered list elements that are contained in a div which has relative positioning: The html structure of the UL: <div id="accountBox" class="account_settings_box"> <ul> <ul> <li class="profileImage"><img src="images/profileimage.jpg" alt="Profile Image" /></li> <li class="profileName">Your name</li> <li class="profileEmail">Your email</li> </ul> <li><a href="">Messages</a></li> <li><a href="">Settings</a></li> <li><a href="">Password</a></li> <li><a href="">Sign out</a></li> </ul> </div> and the CSS for this list: .account_settings_box ul ul { display: inline-block; margin: 0; padding: 0; width: 100%; height: 150px; outline: 1px solid blue; } .account_settings_box ul ul li { display: inline-block; border: none; /* Reset the border */ } .profileImage { float: right; display: block; width: 150px; height: 150px; outline: 1px solid purple; } .profileName, .profileEmail { width: auto; height: auto; width: 150px; height: 150px; } .account_settings_box ul ul li:hover { outline: 1px solid red; } .profileImage img { width: 150px; height: 150px; } I am having difficultly with the embedded ul, i.e, .account_settings_box ul ul element. The image below shows what it currently looks like. I am trying to achieve the follow: Have the image floating to the right, and have the "your name" and "your email" positioned to the left of the image (basically where they are currently). Thanks for your help in advance. Sam :)

  • Download HTML and Images with WGet without first few lines

    - by St. John Johnson
    I'm attempting to use wget with the -p option to download specific documents and the images linked in the HTML. The problem is, the site that is hosting the HTML has some non-html information preceding the HTML. This is causing wget to not interpret the document as HTML and doesn't search for images. Is there a way to have wget strip the first X lines and/or force searching for images? Example URL: http://www.sec.gov/Archives/edgar/data/13239/000119312510070346/ds4.htm First Lines of Content: <DOCUMENT> <TYPE>S-4 <SEQUENCE>1 <FILENAME>ds4.htm <DESCRIPTION>FORM S-4 <TEXT> <HTML><HEAD> <TITLE>Form S-4</TITLE> Last Lines of Content: </BODY></HTML> </TEXT> </DOCUMENT>

  • HTML is not being interpreted after JQuery's .ajax function

    - by Casidiablo
    Hello there... Once I have retrived an HTML string with the $.ajax function I put it into a div... the HTML is a simple message with a <b> tag, but it's not being interpreted by the browser, I mean, the <b> is not making the text bold. Here is what I do: $.ajax({ url: 'index.php?ajax=ejecutar_configuracion&id_gadget=cubrimientos', cache: false, success: function(html){ // html = '<b>hello</b> newton' $('#config_reporte').html(html).dialog({ height: 300, width: 500, modal: true }); } }); As you can see, I'm writing the content of the HTML result into a modal dialog window. Does anybody know why is this happening? This should be something easy to do... but I haven't been able to make it work properly. Thank you so much.

  • C#: Regex to extract portions of file name

    - by jakesankey
    I have text files formatted as such: R156484COMP_004A7001_20100104_065119.txt I need to consistently extract the R****COMP, the 004A7001 number, 20100104 (date), and don't care about the 065119 number. the problem is that not ALL of the files being parsed have the exact naming convention. some may be like this: R168166CRIT_156B2075_SU2_20091223_123456.txt or R285476COMP_SU1_125A6025_20100407_123456.txt So how could I use regex instead of split to ensure I am always getting that serial (ex. 004A7001), the date (ex. 20100104), and the R****COMP (or CRIT)??? Here is what I do now but it only gets the files formatted like my first example. if (file.Count(c => c == '_') != 3) continue; and further down in the code I have: string RNumber = Path.GetFileNameWithoutExtension(file); string RNumberE = RNumber.Split('_')[0]; string RNumberD = RNumber.Split('_')[1]; string RNumberDate = RNumber.Split('_')[2]; DateTime dateTime = DateTime.ParseExact(RNumberDate, "yyyyMMdd", Thread.CurrentThread.CurrentCulture); string cmmDate = dateTime.ToString("dd-MMM-yyyy");

  • search and replace with ruby regex

    - by randombits
    I have a text blob field in a MySQL column that contains HTML. I have to change some of the markup, so I figured I'll do it in a ruby script. Ruby is irrelevant here, but it would be nice to see an answer with it. The markup looks like the following: <h5>foo</h5> <table> <tbody> </tbody> </table> <h5>bar</h5> <table> <tbody> </tbody> </table> <h5>meow</h5> <table> <tbody> </tbody> </table> I need to change just the first <h5>foo</h5> block of each text to <h2>something_else</h2> while leaving the rest of the string alone. Can't seem to get the proper PCRE regex, using Ruby.

  • Regex problem in Java in code sample

    I have job with regex in my expressions: example !(FA1_A.i & FA1_M.i) I have operators ! ( ) & | operands have names [a-zA-Z_]*.[a-zA-Z_] I wrote in Java to split on tokens, but it doesn't split on operators and operands If should be !, (, FA1_A.i, &, FA1_m.i, ) . Can anybody tell me what is wrong ? String stringOpеrator = "([!|&()])"; String stringOperand = "(([a-zA-Z_]*)\\.([a-zA-Z_]*))"; String reg=stringOpеrator+"|"+stringOperand; Pattern pattern = Pattern.compile(reg); Matcher m = pattern.matcher(expression); // System.out.println("func: " + function + " item: " + item); while (m.find()) { int a=m.start(); int b=m.end(); String test=expression.substring(m.start(), m.end()); String g=test; tokens.add(new Token(expression.substring(m.start() , m.end()))); //m = pattern.matcher(expression); }

  • Parsing tnsnames.ora using regex...

    - by Welton v3.50
    I am attempting to pull some information from my tnsnames file using regex. I started with the following pattern: MYSCHEMA *? = *?[\W\w\S\s]*\(HOST *?= *?(?<host>\w+\s?)\)\s?\(PORT *?= *?(?<port>\d+)\s?\)[\W\w\S\s]*\(SERVICE_NAME *?= *?(?<servicename>\w+)\s?\) which worked fine when MYSCHEMA was the only schema in the file, but when there are other schemas listed after MYSCHEMA it matches all the way to the last schema. I have since created a new pattern: MYSCHEMA *=\s*\(DESCRIPTION =\s*\(ADDRESS *= *\(PROTOCOL *= *TCP\)\(HOST *= *(?<host>\w+)\)\(PORT *= *(?<port>\d+)\)\)\s*\(CONNECT_DATA *=\s*(?<serverdedicated>\(SERVER *= *DEDICATED\))\s*\(SERVICE_NAME *= *(?<servicename>[\w\.]+) *\)\s*\)\s*\) This pattern matches MYSCHEMA only, but I had to add every element that appeared in MYSCHEMA entry, and it won't match MYOTHERSCHEMA if it does not contain all the same elements. Ideally, I'd like a pattern that matches MYSCHEMA entry only, and captures HOST, PORT and SERVICE NAME, and optionally (SERVER = DEDICATED) (which I didn't have in the first pattern) to named groups. Below is the sample tnsnames that I've been using for testing: SOMESCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = REMOTEHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = REMOTE) ) ) MYSCHEMA = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1234)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MYSERVICE.LOCAL ) ) ) MYOTHERSCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = MYSERVICE.REMOTE) ) ) SOMEOTHERSCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = LOCALHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = LOCAL) ) )

  • Find & Replace - using a Regex for this?

    - by Jack W-H
    Hey folks. Regexs make me cry, so, I came here for help. I'm looking for some tips on Find & Replace in Panic's Coda. I know the F&R is pretty advance but I'm just looking for the best way to do this. I'm trying to rewrite a 'template engine' (very basic) I have going on with a webapp I'm coding in PHP (CodeIgniter). Currently I'm calling my template like so: $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view('subviews/template/sidebar'); $this->load->view('The-View-I-Want-To-Load'); // This is the important line $this->load->view('subviews/template/footerview'); However it's inefficient using five lines of code every time I want to load up a different page, in every different controller. So I rewrote it like this: $data['view'] = 'The-View-I-Want-To-Load'; $this->load->view('template',$data); That way if I need to make any major changes to the design it can easily be done from the template.php view file (which contains the header, menu, sidebar views etc. etc.). However I use the previous 5-lines all over the place in many different controllers and functions. So, my question is --- How can I find and replace the old template engine (5 lines of code) for the new one - substituting in the name of the view in the important, unique line for the one in $data['view]? Does that make any sense?! If not I'll try and rephrase! I mean, is there a way of doing this via a Regex or something? Or am I on completely the wrong lines here? Thanks for your help Jack

  • .NET RegEx - First N chars of First M lines

    - by George
    Hello! I want 4 general RegEx expressions for the following 4 basic cases: Up to A chars starting after B chars from start of line on up to C lines starting after D lines from start of file Up to A chars starting after B chars from start of line on up to C lines occurring before D lines from end of file Up to A chars starting before B chars from end of line on up to C lines starting after D lines from start of file Up to A chars starting before B chars from end of line on up to C lines starting before D lines from end of file These would allow to select arbitrary text blocks anywhere in the file. So far I have managed to come up with cases that only work for lines and chars separately: (?<=(?m:^[^\r]{N}))[^\r]{1,M} = UP TO M chars OF EVERY LINE, AFTER FIRST N chars [^\r]{1,M}(?=(?m:.{N}\r$)) = UP TO M chars OF EVERY LINE, BEFORE LAST N chars The above 2 expressions are for chars, and they return MANY matches (one for each line). (?<=(\A([^\r]*\r\n){N}))(?m:\n*[^\r]*\r$){1,M} = UP TO M lines AFTER FIRST N lines (((?=\r?)\n[^\r]*\r)|((?=\r?)\n[^\r]+\r?)){1,M}(?=((\n[^\r]*\r)|(\n[^\r]+\r?)){N}\Z) = UP TO M lines BEFORE LAST N lines from end These 2 expressions are equivalents for the lines, but they always return just ONE match. The task is to combine these expressions to allow for scenarios 1-4. Anyone can help? Note that the case in the title of the question, is just a subclass of scenario #1, where both B = 0 and D = 0. EXAMPLE: SOURCE: line1 blah 1 line2 blah 2 line3 blah 3 line4 blah 4 line5 blah 5 line6 blah 6 DESIRED RESULT: Characters 3-6 of lines 3-5: A total of 3 matches: <match>ne3 </match> <match>ne4 </match> <match>ne5 </match>

The error Im getting is: Unrecognized escape \m passed through at 1130.pl line 17. I took a look at http://stackoverflow.com/questions/1040657/how-can-i-grab-multiple-lines-after-a-matching-line-in-perl to get an idea of how to read a file and match a line within it, however im not 100% sure I'm doing this right or in the best way. I also seem to produce the error: Error, my.txt not found. But the file does exist in the folder C:\backups\MySQL\

  • Increasing Regex Efficiency

    - by cam
    I have about 100k Outlook mail items that have about 500-600 chars per Body. I have a list of 580 keywords that must search through each body, then append the words at the bottom. I believe I've increased the efficiency of the majority of the function, but it still takes a lot of time. Even for 100 emails it takes about 4 seconds. I run two functions for each keyword list (290 keywords each list). public List<string> Keyword_Search(HtmlNode nSearch) { var wordFound = new List<string>(); foreach (string currWord in _keywordList) { bool isMatch = Regex.IsMatch(nSearch.InnerHtml, "\\b" + @currWord + "\\b", RegexOptions.IgnoreCase); if (isMatch) { wordFound.Add(currWord); } } return wordFound; } Is there anyway I can increase the efficiency of this function? The other thing that might be slowing it down is that I use HTML Agility Pack to navigate through some nodes and pull out the body (nSearch.InnerHtml). The _keywordList is a List item, and not an array.

  • Regex for removing certain variable numeric values from some text

    - by stephemurdoch
    I want to substitute all 4 instances of the number 300 from the code below, with 470. <div> <object width="300" height="300"> <embed src="link-removed" width="300" height="300"></embed> </object> <p> <a href="another-link">link</a> </p> </div> The width and height of the code being pasted might not always be 300 by 300. So I figure I probably need a regular expression that subs any numeric value that follows the strings "width=" and "height=", whilst remembering to account for the quotations marks that surround the number. Can anyone tell me if that's the best way, and if so, what would be the best regex? In case it matters, the code being pasted is stored as "text" in the db rather than as a string, as it's quite lengthy (i've removed a few hundred chars from what you see pasted here)...
