  • PHP regular expression subpattern behaviour

    - by codecowboy
    I want to match both the src and title attributes of an image tag: pattern: <img [^>]*src=["|\']([^"|\']+["|\'])|title=["|\']([^"|\']+) target: <img src="http://someurl.jpg" class="quiz_caption" title="Caption goes here!"> This pattern gives me one unwanted match, title="content", and the match I actually want which is the value between the quotes after the word 'title', i.e 'content'. So, my matches are: <img src="http://someurl.jpg http://someurl.jpg title="Caption goes here!" Caption goes here! Is there a way to avoid the third of these matches? I'm using PCRE in PHP 5.2.x

  • Is there any Android XML documentation?

    - by Eddified
    Is there any sort of xml reference? I found this which turned out to be invaluable for me http://groups.google.com/group/android-developers/msg/d334017d72909c79 but I can't figure out how I was supposed to know how to do that, had I not found that post. I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using , , tags? I'd really like to know where I can find such documentation.

  • How to write to an XML file from the iPad OS?

    - by user345474
    I am developing an app for IPad, and I need to modify several attributes in a XML file at runtime. I found the class NSXMLDocument, http://developer.apple.com/mac/library/documentation/cocoa/reference/foundation/Classes/NSXMLDocument_Class/Reference/Reference.html But I haven't been able to import it to my project. Is this class not available for IPhone/IPad development? Is there some other approach I can consider? I read about libxml library. Is it my answer or there is a better approach?

  • How to get selenium to click on an object other than by ID

    - by Zombies
    So here is a little challenge. I have an image. It has 2 attributes: a random ID - not helpful an image url - but it is a button, and other buttons use the same image url, not helpful a CSS class - also used by too many other things to be helpful a style - neither helpful nor unique This image is however inside of an anchor tag, but the anchor tab isn't to a page, it just runs some javascript. Bellow is the html in question: <a id="template:j_id__ctru168pc2" title="Click for the Manual Class LOV" class="xei" style="text-decoration: none;" onclick="return false;" href="#"> <img id="template:j_id__ctru169pc2" class="xgs" style="border: 0pt none;" src="images/lov_ena.png"> </a> How can I click this image without using the ID?

  • Reading data from a MySQL database into a HTML Table?

    - by Michael McKay
    So i am working on a project and need some advice. I have a MySQL database that stores events, i know how to code this functionality in PHP but im just stuck of a few specifics. As the project that I am creating is a timetable, the most important attributes are the day of the event, starting time and finishing time. Once i have read this data from the MYSQL database using my PHP script, how do i go about inserting these events in to a html timetable? Lets say i have record like below in my events table: Event ID = 01 Event Day = Monday Event Start = 12:00 Event End = 14:00 How would I then put that into a html table, bearing in mind that i may have mutiple events for a day?

  • Validate decimal number in (known) national format

    - by Álvaro G. Vicario
    PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

  • asp.net mvc. Inserting string data from model into javascript. best-practice

    - by Andrew Florko
    Hello everybody, I have to populate javascript code in html layout (hidden fields, method params) with string data from model. Html.Encode is not appropriate for my task because it encodes ' symbol, bypass : (that ruines object attributes declaration) and so on. I wrote static helper class that is used from View like this: alert('<%=ViewHelper.MakeJavaScriptSafe(Model.Message)%>'); I hope there is asp.net in-built function I don't know about for this task. Does it exist really? Thank you in advance.

  • Using Dom Objects in PHP, the default namespace is redeclared in some nodes.

    - by TomcatExodus
    I'm working on a template engine, having migrated from regex driven to DOM driven. It appears though, that whenever I create a DomDocumentFragment to encapsulate some portion of a document temporarily, the namespace attribute is added to each node in the fragment. Since my default namespace for a given document will 99% of the time be XHTML, it's adding the XHTML namespace declaration. Being the default namespace, this seems fruitless, and ultimately nodes in any other namespace will be stripped out at render time anyways. Aside from iteratively removing namespace attributes, is there some way I can prevent this from occurring to begin with? Its quite problematic, as this will likely increase render time filesize considerably, as large portions of a given document may be stored in a fragment. I've tried $doc->normalizeDocument(), but as I assumed, it did nothing.

  • Simple user control for conditionally rendering nested HTML

    - by Goyuix
    What I would like to do, is be able to pass two attributes to a user control, a ListName and a Permission, like so: <uc:check id="uc" List="Shared Documents" Permission="OpenItems" runat="server"> <!-- have some HTML content here that is rendered if the permission is true --> </uc:check> Then in the actual check user control, have something similar to: <%@ Control language="C#" ClassName="check" %> <% // determine permission magic placeholder if (DoesUserHavePermissions(perm)) { // render nested HTML content } else { // abort rendering as to not show nested HTML content } %> I have read the page on creating a templated control on MSDN, and while that would work - it really seems to be a bit overkill for what I am trying to do. Is there a control that already renders content based on a boolean expression or a simpler template example? http://msdn.microsoft.com/en-us/library/36574bf6.aspx

  • Update model objects across different activities

    - by Tom Esterez
    Lets say I have 2 activities: A: A ListView displaying articles titles. Data is fetched from a web server and converted from XML to a list of ArticleSummary. Only user titles and id are returned by the server. Click on a title starts activity B. B: A form to edit an article. Article is fetched from server. When the user hits OK, modifications are sent to the server and activity closed. When the user go back to activity A, I would like to update the article title without any additional web request. I was thinking about the following solution: When article is modified, send a broadcast event with article id and new attributes values. Listen for this event on activity A Update the ArticleSummary object notify data changed on ListView Is there a better approach ?

  • Big task - problems with page refresh and ajax

    - by user1830414
    I have a navigation which load dynamically content via ajax. But if I refresh the page or visit another url and go back the current content is away and I see the old content under the first menu tab. Now I have to solve this problem. The index.php include the elements header_registrated.inc.php, navigation.inc.php and main_container.inc.php index.php: <?php include("inc/incfiles/header_registrated.inc.php"); ?> <?php if (!isset($_SESSION["userLogin"])) { echo "<meta http-equiv=\"refresh\" content=\"0; url=http://localhost/project\">"; } else { echo ""; } ?> <?php include("inc/incfiles/navigation.inc.php"); ?> <?php include("inc/incfiles/main_container.inc.php"); ?> <?php include("inc/incfiles/footer.inc.php"); ?> header_registrated.inc.php: <?php include ("inc/scripts/mysql_connect.inc.php"); session_start(); $user = $_SESSION["userLogin"]; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>title</title> <link href="css/style.css" rel="stylesheet" type="text/css" /> <script language="JavaScript" src="js/framework/jquery.js"></script> <script language="JavaScript" src="js/dropdown/window.js"></script> <script language="JavaScript" src="js/navigation/navigation.js"></script> </head> <body> </body> navigation.inc.php: <div class="navigation"> <ul> <li id="1"> <div id="menuImage1" class="menuImage"></div> <div class="menuText"><p>Punkt 1</p></div> <div class="navigationDart"></div> </li> <li id="2"> <div id="menuImage2" class="menuImage"></div> <div class="menuText"><p>Punkt 2</p></div> </li> <li id="3"> <div id="menuImage3" class="menuImage"></div> <div class="menuText"><p>Punkt 3</p></div> </li> <li id="4"> <div id="menuImage4" class="menuImage"></div> <div class="menuText"><p>Punkt 4</p></div> </li> <li id="5"> <div id="menuImage5" class="menuImage"></div> <div class="menuText"><p>Punkt 5</p></div> </li> <li id="6"> <div id="menuImage6" class="menuImage"></div> <div class="menuText"><p>Punkt 6</p></div> </li> </ul> </div> main_container.inc.php: <div class="mainContainer"> <div class="containerHeader"> <div class="contentHeader"> </div> </div> <div class="contentContainer"> <div class="content"> </div> <div class="advertisement"> </div> </div> </div> Now the divs content, cnotentHeader and advertisement (in file main_content.inc.php) is filled via ajax.

Please help me. I have the feeling that I've searched the whole web to find an answer.

  • In Java how instance of and type cast(i.e (ClassName)) works on proxy object ?

    - by learner
    Java generates a proxy class for a given interface and provides the instance of the proxy class. But when we type cast the proxy object to our specific Object, how java handles this internally? Is this treated as special scenario? For example I have class 'OriginalClass' and it implements 'OriginalInterface', when I create proxy object by passing 'OriginalInterface' interface java created proxy class 'ProxyClass' using methods in the provided interface and provides object of this class(i.e ProxyClass). If my understanding is correct then can you please answer following queries 1) When I type cast object of ProxyClass to my class OriginalClass this works, but how java is allowing this? Same in case of instace of? 2) As my knowledge java creates a proxy class only with the methods, but what happen when I try to access attributes on this object? 3) Only interface methods are getting implemented in Proxy, but what happens when I try to access a method which not in interface and only mentioned in the class? Thanks, Student

  • Java, searching within a list of objects?

    - by Rick
    I'm a bit lost on the way to make this happen the fastest. I have a large list of objects that have basic variable attributes (with getters / setters) and I need to do a search in this list to find the objects within the list that match a given parameter I have found how to do a regular list search but I need to, for example search for the value of the result of doing a call getName() for each object in the list and get objects that have a result that matches my input. Something like below where the third argument is the result of the method call and the second is what I am trying to find. int index = Collections.binarySearch(myList, "value", getName()); Any advice is appreciated

  • design function: underlying structure to store list of results for print to file

    - by forest.peterson
    is this a good approach to print a list of items to csv file with a sublist attached to each item. The gist of the function is when an item is found that does not exactly macth then a list of close matches is generated - this works now writing out one list at a time to a command window. For export to a csv file I think all the lists must be generated, stored and then written at once. Right now I use a struct to store the attributes printed, each struct is an item on the list - these structs are then added to a sorted stack and when printed they pop off into write out. Is a stack of stacks of structs a good design?

  • Match e-mail addresses not contained in HTML tag

    - by SvartalF
    I need to highlight an email addresses in text but not highlight them if contained in HTML tags, content, or attributes. For example, the string [email protected] must be converted to <a href="mailto:[email protected]">[email protected]</a> But email addresses in the string <a href="mailto:[email protected]">[email protected]</a> must not be processed. I've tried something like this regexp: (?<![":])[a-zA-Z0-9._%-+]+@[a-zA-Z0-9._%-]+.[a-zA-Z]{2,6}(?!") but it doesn't work properly.

  • Large strings: Text files or SQL DB?

    - by Tommo
    I am coding a forum system using PHP. I am currently storing a threads ID, title, author, views and other attributes in an SQL database and then storing the thread body (the HTML and BBcode) in text files inside a folder named after the thread ID. In practise it's really simple to grab the database values then just grab the thread body from the text file, but I was wondering if this is the 'proper way'? I have personally no problems doing this but if it turns out it is massively inefficient and I should instead store both the thread body HTML and BBcode in the database instead then I will change. However, to me it seems wrong to store such a (very possibly) huge string of multi-line text along with lots of different characters in a database - I was taught that databases are more for short field 'values' rather than website content. I would just like a definitive answer to this because it's been bugging me for ages as to wherever I’ve been doing it properly. Does anyone know how popular forum systems store threads?

    I'm implementing an app using spring security 3.0.2 with OpenId login and registration. I can login succesfully, but if the user isn't registered i want to do: 1) Get some OpenId attributes like email and name. 2) Show to the user a registration form with just these two fields and the OpenId URI filled. I've been searching a lot but i didn't find an "ellegant" way of doing this. I wonder if some of u can come out with a solution to implement this strategy in my app. Thanks in advance.

  • Is it possible to write a SQL query to return specific rows, but then join some columns of those row

    - by Rob
    I'm having trouble wrapping my head around how to write this query. A hypothetical problem that is that same as the one I'm trying to solve: Say I have a table of apples. Each apple has numerous attributes, such as color_id, variety_id and the orchard_id they were picked from. The color_id, variety_id, and orchard_id all refer to their respective tables: colors, varieties, and orchards. Now, say I need to query for all apples that have color_id = '3', which refers to yellow in the colors table. I want to somehow obtain this yellow value from the query. Make sense? Here's what I was trying: SELECT * FROM apples, colors.id WHERE color_id = '3' LEFT JOIN colors ON apples.color_id = colors.id

  • How can I display a list of three different Models sortable by the same :attribute in rails?

    - by Angela
    I have a Campaign model which has_many Calls, Emails, and Letters. For now, these are each a separate Model with different controllers and actions (although I would like to start to think of ways to collapse them once the models and actions stabilize). They do share two attributes at least: :days and :title I would like a way to represent all the Calls, Emails, and Letters that belong_to a specific Campaign as a sortable collection (sortable by :days), in a way that outputs the model name and the path_to() for each. For example (I know the below is not correct, but it represents the kind of output/format I've been trying to do: @campaign_events.each do |campaign_event| <%= campaign_event.model_name %> <%= link_to campaign_event.title, #{model_name}_path(campaign_event) %> end Thanks so much. BTW, if this matters, I would then want to make the :days attribute editable_in_place.

Instead i want that the function will get a directory for example c:\ And it will return me a List of all directories in c:\ Not subsirectories just the directories in c:\ in my case it should be a List with a 14 directories. Meaning in each index in the List a directory. How can i do it ? Tried with Directory and DirectoryInfo but i just got messed up.
