  • Match a comma followed by a newline with a regular expression

    - by MarathonStudios
    I have a comma delimited list I want to import into a database, and in some cases the last item is blank: item1, item2, item3 item1, item2, item1, item2, I'd like to replace all of these empty columns with a placeholder value using a regexp item1, item2, item3 item1, item2, PLACEHOLDER item1, item2, PLACEHOLDER I tried preg_replace("/,\n/", ",PLACEHOLDER\n",$csv);, but this isn't working. Anyone know what regexp would work for this?

  • I want to learn a new language!

    - by Alex
    Hi, I'm a college student majoring in computer science. I know java and will be learning C++ the next couple years at school. I want to add another language to my repertoire and have gotten conflicting advice: Ruby, Python, Perl, JavaScript, PHP, AJAX, among others. I was wondering what everyone's opinions were on the relative value of each of these languages in the job market, the ease of learning of each of the languages, and just personal preferences when it comes to the languages mentioned above. Thanks!

  • javascript validate zip regular expression

    - by phil
    It's not working. Probably it's syntax error, but I can't figure it out. <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <script> pattern=/^[0-9]{5}$/; if (!pattern.test($('#zip').val)) {$('#zip').append($('<p>',{html: zip is invalid}));} </script> zip (US only): <input type="text" name='zip' id='zip' maxlength="5">

  • What are the things Java got right?

    - by hamletdarcy
    What are the things that Java (the language and platform) got categorically right? In other words, what things are more recent programming languages preserving and carrying forward? Some easy answer are: garbage collection, a VM, lack of pointers, classloaders, reflection(?) What about language based answers? Please don't list the things Java did wrong, just right. (note by Mark Harrison) This is an interesting and useful question, especially for those of us who don't use java regularly. I'm voting for reopening. Please don't close as argumentative, as it doesn't seem to be causing any arguments.

  • How do I not include part of a regular expression

    - by Axilus
    I'm pretty new to using regexes and I can figure out how I would go about extracted a specific number from a string. Suppose the string was any amount of whitespace or random text and somewhere within it is this, "Value: $1000.00." In order to retrieve that value I am currently using this: string value = Convert.ToString(Regex.Match(BodyContent, @"Value:[ \t]*\$?\d*(\.[0-9]{2})?", RegexOptions.Singleline)); So the variable 'value' now has, "Value: $1000.00" stored in it. My question is, using Regex is there a way to use 'Value:' to find the number value but only store the actual number value (i.e. 1000.00) in the 'value' variable?

  • What language is .NET Framework written in?

    - by chester89
    The question I always wanted to ask and was afraid to, actually - what language is .NET Framework written in? I mean library itself. It seems to me that it was C and C++ mostly. (I hope Jon Skeet is reading this one, it`ll be very interesting to hear what he thinks about it)

  • Best cross-language analyzer to use with lucene index

    - by Halirob
    Hello, I'm looking for feedback on which analyzer to use with an index that has documents from multiple languages. Currently I am using the simpleanalyzer, as it seems to handle the broadest amount of languages. Most of the documents to be indexed will be english, but there will be the occasional double-byte language indexed as well. Are there any other suggestions or should I just stick with the simpleanalyzer. Thanks

  • Regular expression Not working properly n case of multiple trailing ]]]]

    - by ronan
    I have the requirement that in a textbox a user can jump to the next word enclosed in [] on a tab out for example Hi [this] is [an] example. Testing [this] So when my cursor is at Hi and I do a tab out , the characters enclosed in the [this] are highlighted and when I again do a tabl out th next characters enclosed in following [an] are highlighted. This works fine Now the requirement is whatever the text including the special chars between [] needs to be highlighted case 1: when I have trailing ]]], it only highlights leading [[[ and ignores ]]]] e.g case 2: In case of multiple trailing ] e.e [this]]]] is [test], ideally one a single tabl out from this , it should go to next text enclosed in [] but a user has to tab out 4 times one tab per training ] to go to next [text] strong text The code is $(document).ready(function() { $('textarea').highlightTextarea({ color : '#0475D1', words : [ "/(\[.*?\])/g" ], textColor : '#000000' }); $('textarea').live('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { var currentIndex = getCaret($(this).get(0)) selectText($(this), currentIndex); return false; } }); }); function selectText(element, currentIndex) { var rSearchTerm = new RegExp(/(\[.*?\])/); var ind = element.val().substr(currentIndex).search(rSearchTerm) currentIndex = (ind == -1 ? 0 : currentIndex); ind = (ind == -1 ? element.val().search(rSearchTerm) : ind); currentIndex = (ind == -1 ? 0 : currentIndex); var lasInd = (element.val().substr(currentIndex).search(rSearchTerm) == -1 ? 0 : element.val().substr(currentIndex).indexOf(']')); var input = element.get(0); if (input.setSelectionRange) { input.focus(); input.setSelectionRange(ind + currentIndex, lasInd + 1 + currentIndex); } else if (input.createTextRange) { var range = input.createTextRange(); range.collapse(true); range.moveEnd('character', lasInd + 1 + currentIndex); range.moveStart('character', ind + currentIndex); range.select(); } } function getCaret(el) { if (el.selectionEnd) { return el.selectionEnd; } else if (document.selection) { el.focus(); var r = document.selection.createRange(); if (r == null) { return 0; } var re = el.createTextRange(), rc = re.duplicate(); re.moveToBookmark(r.getBookmark()); rc.setEndPoint('EndToStart', re); return rc.text.length; } return 0; } Please let me know to handle two above cases

  • C# : Regular Expression

    - by Pramodh
    I'm having a set of row data as follows List<String> l_lstRowData = new List<string> { "Data 1 32:01805043*0FFFFFFF", "Data 3, 20.0e-3", "Data 2, 1.0e-3 172:?:CRC" , "Data 6" }; and two List namely "KeyList" and "ValueList" like List<string> KeyList = new List<string>(); List<string> ValueList = new List<string>(); I need to fill the two List<String> from the data from l_lstRowData using Pattern Matching And here is my Pattern for this String l_strPattern = @"(?<KEY>(Data|data|DATA)\s[0-9]*[,]?[ ][0-9e.-]*)[ \t\r\n]*(?<Value>[0-9A-Za-z:?*!. \t\r\n\-]*)"; Regex CompiledPattern=new Regex(l_strPattern,RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace); So finally the two Lists will contain KeyList { "Data 1" } { "Data 3, 20.0e-3" } { "Data 2, 1.0e-3" } { "Data 6" } ValueList { "32:01805043*0FFFFFFF" } { "" } { "172:?:CRC" } { "" } Scenerio: The Group KEY in the Pattern Should match "The data followed by an integer value , and the if there exist a comma(,) then the next string i.e a double value The Group Value in the Pattern should match string after the whitespace.In the first string it should match 32:01805043*0FFFFFFF but in the 3rd 172:?:CRC. Here is my sample code for (int i = 0; i < l_lstRowData.Count; i++) { MatchCollection M = CompiledPattern.Matches(l_lstRowData[i], 0); KeyList.Add(M[0].Groups["KEY"].Value); ValueList.Add(M[0].Groups["Value"].Value); } But my Pattern is not working in this situation. Please help me to rewrite my Pattern.

  • Are there any embedded languages that can be embedded into C# and actionscript?

    - by AnthonyF
    I'm looking for a embedded language that can be used to script common code between a server app written in C# and a client app written in Flash/Actionscript. It is important that the embedded language interpreter run natively in the environment it is embedded into. For example, it cannot load any external C libraries (i.e. python, neko). Does such a thing exist for these two languages? Perhaps there is some minimal interpreter that could be easily ported to both? Thanks!

  • regular expression not behaving as expected - Python

    - by philippe
    I have the following function which is supposed to read a .html file and search for <input> tags, and inject a <input type='hidden' > tag into the string to be shown into the page. However, that condition is never met:( e.g the if statement is never executed. ) What's wrong with my regex? def print_choose( params, name ): filename = path + name f = open( filename, 'r' ) records = f.readlines() print "Content-Type: text/html" print page = "" flag = True for record in records: if re.match( '<input*', str(record) ) != None: print record page += record page += "<input type='hidden' name='pagename' value='psychology' />" else: page += record print page Thank you

  • regular expressions: 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?

  • Java regular expression: how to include '-'

    - by changed
    I am using this pattern and matching a string. String s = "//name:value /name:value"; if (s.matches("(//?\\s*\\w+:\\w+\\s*)+")) { // it fits } This works properly. But if I want to have a string like "/name-or-address:value/name-or-address:value" which has this '-' in second part, it doesn't work. I am using \w to match A-Za-z_, but how can I include - in that?

  • python regular expressions, how to extract longest of overlapping groups

    - by xulochavez
    Hi How can I extract the longest of groups which start the same way For example, from a given string, I want to extract the longest match to either CS or CSI. I tried this "(CS|CSI).*" and it it will return CS rather than CSI even if CSI is available. If I do "(CSI|CS).*" then I do get CSI if it's a match, so I gues the solution is to always place the shorter of the overlaping groups after the longer one. Is there a clearer way to express this with re's? somehow it feels confusing that the result depends on the order you link the groups.
