• Regular Expressions - Match all alphanumeric characters except individual numbers

  - by imaginonic

  I would like to create a RegEx to match only english alphanumeric characters but ignore (or discard) isolated numbers in Ruby (and if possible in JS too). Examples: 1) I would like the following to be matched: 4chan 9gag test91323432 asf5asdfaf35edfdfad afafaffe But not: 92342424 343424 34432 and so on.. The above is exactly what I would want. 2) However, I would be really thankful if someone could also include French letters like: é ë ê (These are just few examples of many) 1) is my priority, it's totally okay if 2) is impossible or difficult to implement. Sorry, my regex skills aren't that great (hence this question!) Thank you.

• Does the XML specification states that parser need to convert \n\r to \n always, even when \n\r appe

  - by mic.sca

  Hi, I've stumbled in a problem handling the \line-feed and \carriage-return characters in xml. I know that, according to http://www.w3.org/TR/REC-xml/#sec-line-ends, xml processors are required to replace any "\n\r" or lone "\r" sequences with "\n". The specification states that this has to be the behaviour for handling any "external parsed entity", does this apply to CDATA sections inside of an element as well? thank you, Michele I'm sure that msxml library for example converts every \n\r" or lone "\r" sequences to "\n", regardless of their being in a cdata section or not.

• C#: split a string into runs of characters, numbers and delimited strings and process it

  - by nrkn

  OK my regex is a bit rusty and I've been struggling with this particular problem... I need to split and process a string containing any number of the following, in any order: Chars (lowercase letters only) Quote delimited strings Ints The strings are pretty weird (I don't have control over them). When there's more than one number in a row in the string they're seperated by a comma. They need to be processed in the same order that they appeared in the original string. For example, a string might look like: abc20a"Hi""OK"100,20b With this particular string the resulting call stack would look a bit like: ProcessLetters( new[] { 'a', 'b', 'c' } ); ProcessInts( 20 ); ProcessLetters( 'a' ); ProcessStrings( new[] { "Hi", "OK" } ); ProcessInts( new[] { 100, 20 } ); ProcessLetters( 'b' ); What I could do is treat it a bit like CSV, where you build tokens by processing the characters one at a time, but I think it could be more easily done with a regex?

• SQL Server - Searching string with international characters using LIKE clause

  - by Nikhil

  Hi, I have a field 'Description' which can have product descriptions with any unicode characters. If I search for a description which contains an international character, with a LIKE condition (word searched with does not have the international character) I get the following results: Ex: GEWÜRZTRAMINER is one of the descriptions. When I do: Select * from table where Description LIKE '%GEWURZTRAMINER%', it retrieves the entry. When I do: Select * from table where Description LIKE '%GEWURZ%', the entry is not retrieved. (Note: the search condition does not include the Ü but has a U) Is there a way around this so that I can retrieve with '%GEWURZ%' as well? SQl Server 2008

• Checking if a string's characters are ascending alphabetically and its ascent is evenly spaced python

  - by FRU5TR8EDD

  So need to check if a string's characters are ascending alphabetically and if that ascent is evenly spaced. a = "abc" b = "ceg" So a is alphabetically ascending and it's spacing is 1 (if you convert to the ordinal values they are 97,98,99). And b is also alphabetically ascending and it's spacing is 2 (99,101,103). And I am sticking with the following code: a = 'jubjub' words1 = [] ords = [ord(letter) for letter in a] diff = ords[1] - ords[0] for ord_val in range(1, len(ords)-1): if diff > 0: if ords[ord_val + 1] - ords[ord_val] == diff: if a not in words1: words1.append((a, diff)) print words1 How come 'jubjub' works, 'ace' works, but 'catcat' doesn't?

• Alt attribute encoding with JavaScript

  - by MainMa

  Hi, Html entities must be encoded in alt attribute of an image in HTML page. So <img id="formula" alt="A &rarr; B" src="formula.png" /> will work well. On the other hand, the same JavaScript code will not work document.getElementById('formula').alt = 'A &rarr; B'; and will produce A &rarr; B instead of A → B. How to do it through JavaScript, when it is not possible to put the special (unencoded) characters in the source code?

• escaping query string with special characters with python

  - by that_guy

  I got some pretty messy urls that i got via scraping here, problem is that they contain spaces or other special characters in the path and query string, here is some example http://www.example.com/some path/to the/file.html http://www.example.com/some path/?file=path to/file name.png&name=name.me so, is there an easy and robust way to escape the urls so that i can pass them to urlopen? i tried urlib.quote, but it seems to escape the '?', '&', and '=' in the query string as well, and it seems to escape the protocol as well, currently, what i am trying to do is use regex to separate the protocol, path name, and query string and escape them separately, but there are cases where they arent separated properly any advice is appreciated

• file_get_contents() removing tab and new line characters

  - by Patrick Murray

  I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

• C# Console Application - Odd behaviour - char '\a'

  - by KHT

  After extensive debugging of an application, I noticed the console window would hang when searching text for the char '\a'. The goal is to strip out characters from a file. The console window would always hang upon exiting the program, and it would make it to the last statement of main. I removed the '\a' from the switch statement and the console application does not hang anymore. Any idea why? I still need to strip out the char '\a', but cannot get the application to work without hanging. switch (c) { case '\t': //Horizontal Tab case '\v': //Vertical Tab case '\n': //Newline case '\f': //Form feed case '\r': //carriage return case '\b': //Backspace case '\x7f': //delete character case '\x99': //TM Trademark case '\a': //Bell Alert **REMOVED THIS** return true; }

I cannot think of a suitable css selector. But myabe one of you guys (or girls) know a solution. Is this possible at all?

• formatting european characters from JSON results

  - by mlecho

  hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

• Wierd characters in exported csv files when converting

  - by Ahue

  Hey guys, I came across a problem I cannot solve on my own concerning the downloadable csv formatted trends data files from Google Insights for Search. I'm to lazy to reformat the files I4S gives me manually what means: Extracting the section with the actual trends data and reformatting the columns so that I can use it with a modelling program I do for school. So I wrote a tiny script the should do the work for me: Taking a file, do some magic and give me a new file in proper format. What it's supposed to do is reading the file contents, extracting the trends section, splitting it by newlines, splitting each line and then reorder the columns and maybe reformat them. When looking at a untouched I4S csv file it looks normal containing CR LF caracters at line breaks (maybe thats only because I'm using Windows). When just reading the contents and then writing them to a new file using the script wierd asian characters appear between CR and LF. I tried the script with a manually written similar looking file and even tried a csv file from Google Trends and it works fine. I use Python and the script (snippet) I used for the following example looks like this: # Read from an input file file = open(file,"r") contents = file.read() file.close() cfile = open("m.log","w+") cfile.write(contents) cfile.close() Has anybody an idea why those characters appear??? Thank you for you help! I'll give you and example: First few lines of I4S csv file: Web Search Interest: foobar Worldwide; 2004 - present Interest over time Week foobar 2004-01-04 - 2004-01-10 44 2004-01-11 - 2004-01-17 44 2004-01-18 - 2004-01-24 37 2004-01-25 - 2004-01-31 40 2004-02-01 - 2004-02-07 49 2004-02-08 - 2004-02-14 51 2004-02-15 - 2004-02-21 45 2004-02-22 - 2004-02-28 61 2004-02-29 - 2004-03-06 51 2004-03-07 - 2004-03-13 48 2004-03-14 - 2004-03-20 50 2004-03-21 - 2004-03-27 56 2004-03-28 - 2004-04-03 59 Output file when reading and writing contents: Web Search Interest: foobar ??????????? ? ? ? ????????? ????????? ???? ??????

• Removing control / special characters from log file

  - by digitalsky

  I have a log file captured by tclsh which captures all the backspace characters (ctrl-H, shows up as "^H") and color-setting sequences (eg. ^[[32m .... ^[[0m ). What is an efficient way to remove them? ^[...m This one is easy since, I can just do "sed -i /^[.*m//g" to remove them ^H Right now I have "sed -i s/.^H//", which "applies" a backspace, but I have to keep looping this until there are no more backspaces. while [ logfile == `grep -l ^H logfile` ]; do sed -i s/.^H// logfile ; done; "sed -i s/.^H//g" doesn't work because it would match consecutive backspaces. This process takes 11 mins for my log file with ~6k lines, which is too long. Any better ways to remove the backspace?

• How to start develop for chinese mobile phones based on nucleus RTOS? (MTK)

  - by juckobee

  I've noticed that chinese mobile phones became very popular, perhaps because of their very reasonable price and many modern features (touch screens, advanced multimedia, double sim cards etc). I'm wondering if there's any way to develop custom solutions for this handsets as independent developer? How to obtain a toolkit and documentation? I've found some resources, but mainly inconsistent tech notes, often in chinese only. For now I know, that majority of chinese handsets are based on chips from MediaTek (MTK), with operating system based on Nucleus RTOS and MMI (plutoMMI?) framework. Unfortunately, there is no Java RE avaiable (ok, there are some handsets with Java, however, Java isn't something I'm looking for) Is there any SDK, documentation, emulators/simulators, how-tos, etc avaiable? How to develop, deploy and test custom application for MTK mobile?

• Why can I not view foreign language characters in my mysql DB?

  - by Chris

  I am inserting the following characters into my DB: ?? / ?? This is the meta tag on the page that is inserting the characters: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> I have altered all the columns in my table that is holding the characters to be utf8_unicode_ci The foreign characters show up like so in the DB: 汉字 / 漢字 When I use a sql statement to display those foreign characters on a page, they display correctly again as: ?? / ?? I am guessing I have some setting that is not correct in my DB, since it stores it correctly, but does not display it correctly. What can i do to make the foreign language characters to display correctly in my DB?

• What regular expression do I need to check for some non-latin characters?

  I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

• jQuery: AJAX umlauts & special characters are a mess

  - by rayne

  I've just created my first ajax function with jQuery which actually works, but unfortunately the character encoding (for characters like ä, ö, ü, ß, c, c, å, ø) is a nightmare. My files and my database are all UTF-8. I've tried a multitude of options in the ajax function and the PHP function, none of which were satisfactory. This is my ajax var dataString = { 'name': name, 'mail': mail // other stuff } $.ajax({ type: "POST", url: "/post.php", data: dataString, contentType: "application/x-www-form-urlencoded;charset=UTF-8", cache: false, success: function(html){ // do stuff } I've tried it without contentType: "application/x-www-form-urlencoded;charset=UTF-8" and I've tried to wrap the affected data in encodeURIComponent(), none of which worked. When I use that AJAX with htmlentities() in my php, my umlauts look like this in plain text: UE Ã?, AE Ã?, OE Ã?, ue ü, ae ä, oe o And like this in the database: UE Ãœ , AE Ä, OE Ö, ue ü, ae ä, oe o If I don't use htmlentities() but mysql_real_escape_string() instead (or neither), they look good in plain text, but they look like this in the database: AE Ä, OE Ö, UE Ãœ, ae ä oe ö ue ü I've been trying tons of options for hours now, but I can't find a solution that works. So far the only option I seem to have is having them look like a total mess in the database, but that would be very contraproductive if those data sets need to be edited.

• Best way to escape characters before jquery post ASP.NET MVC

  - by Darcy

  Hello, I am semi-new to ASP.NET MVC. I am building an app that is used internally for my company. The scenario is this: There are two Html.Listbox's. One has all database information, and the other is initally empty. The user would add items from the database listbox to the empty listbox. Every time the user adds a command, I call a js function that calls an ActionResult "AddCommand" in my EditController. In the controller, the selected items that are added are saved to another database table. Here is the code (this gets called every time an item is added): function Add(listbox) { ... //skipping initializing code for berevity var url = "/Edit/AddCommand/" + cmd; $.post(url); } So the problem occurs when the 'cmd' is an item that has a '/', ':', '%', '?', etc (some kind of special character) So what I'm wondering is, what's the best way to escape these characters? Right now I'm checking the database's listbox item's text, and rebuilding the string, then in the Controller, I'm taking that built string and turning it back into its original state. So for example, if the item they are adding is 'Cats/Dogs', I am posting 'Cats[SLASH]Dogs' to the controller, and in the controller changing it back to 'Cats/Dogs'. Obviously this is a horrible hack, so I must be missing something. Any help would be greatly appreciated.

• C file read leaves garbage characters

  - by KJ

  Hi. I'm trying to read the contents of a file into my program but I keep occasionally getting garbage characters at the end of the buffers. I haven't been using C a lot (rather I've been using C++) but I assume it has something to do with streams. I don't really know what to do though. I'm using MinGW. Here is the code (this gives me garbage at the end of the second read): include include char* filetobuf(char *file) { FILE *fptr; long length; char *buf; fptr = fopen(file, "r"); /* Open file for reading */ if (!fptr) /* Return NULL on failure */ return NULL; fseek(fptr, 0, SEEK_END); /* Seek to the end of the file */ length = ftell(fptr); /* Find out how many bytes into the file we are */ buf = (char*)malloc(length+1); /* Allocate a buffer for the entire length of the file and a null terminator */ fseek(fptr, 0, SEEK_SET); /* Go back to the beginning of the file */ fread(buf, length, 1, fptr); /* Read the contents of the file in to the buffer */ fclose(fptr); /* Close the file */ buf[length] = 0; /* Null terminator */ return buf; /* Return the buffer */ } int main() { char* vs; char* fs; vs = filetobuf("testshader.vs"); fs = filetobuf("testshader.fs"); printf("%s\n\n\n%s", vs, fs); free(vs); free(fs); return 0; } The filetobuf function is from this example http://www.opengl.org/wiki/Tutorial2:_VAOs,_VBOs,_Vertex_and_Fragment_Shaders_%28C_/_SDL%29. It seems right to me though. So anyway, what's up with that?

• Problem between Glassfish and Spring Security Basic Authentication

  - by Raspayu

  Hi! I am enabling a simple HTTP Basic Authentication with Spring security in my project. My environment is an Glassfish Server (bundled with Netbeans), and almost everything works perfect: I have set up it to just ask for authentication with the POST method, with hardcoded users with "user-service", and it works with user names with no special characters. The problem comes when I set up an user with "@" or "." Here is the spring-security related part of my servlet.xml: <security:http> <security:intercept-url method="POST" pattern="/**" access="ROLE_USER" /> <security:http-basic/> </security:http> <security:authentication-manager alias="authenticationManager"> <security:authentication-provider user-service-ref="uservice"/> </security:authentication-manager> <security:user-service id="uservice"> <security:user name="[email protected]" password="pswd1" authorities="ROLE_USER" /> <security:user name="[email protected]" password="pswd2" authorities="ROLE_USER" /> <security:user name="pepe" password="pepito" authorities="ROLE_USER" /> </security:user-service> I have looked also for what did the browser send to the listening port, and it sends right the par "username:password" in base 64, so i think the problem is in my server(Glassfish v3). Does anyone have any idea? Thanks in advance! Raspayu

• How to parse kanji numeric characters using ICU?

  - by Aki

  I'm writing a function using ICU to parse an Unicode string which consists of kanji numeric character(s) and want to return the integer value of the string. "?" = 5 "???" = 31 "???????" = 5972 I'm setting the locale to Locale::getJapan() and using the NumberFormat::parse() to parse the character string. However, whenever I pass it any Kanji characters, the parse() method is returning U_INVALID_FORMAT_ERROR. Does anyone know if ICU supports Kanji character strings in the NumberFormat::parse() method? I was hoping that since I'm setting the Locale to Japanese that it would be able to parse Kanji numeric values. Thanks! #include <iostream> #include <unicode/numfmt.h> using namespace std; int main(int argc, char **argv) { const Locale &jaLocale = Locale::getJapan(); UErrorCode status = U_ZERO_ERROR; NumberFormat *nf = NumberFormat::createInstance(jaLocale, status); UChar number[] = {0x4E94}; // Character for '5' in Japanese '?' UnicodeString numStr(number); Formattable formattable; nf->parse(numStr, formattable, status); if (U_FAILURE(status)) { cout << "error parsing as number: " << u_errorName(status) << endl; return(1); } cout << "long value: " << formattable.getLong() << endl; }
