  • 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

  • Web scraping: how to get scraper implementation from text link?

    - by isme
    I'm building a java web media-scraping application for extracting content from a variety of popular websites: youtube, facebook, rapidshare, and so on. The application will include a search capability to find content urls, but should also allow the user to paste a url into the application if they already where the media is. Youtube Downloader already does this for a variety of video sites. When the program is supplied with a URL, it decides which kind of scraper to use to get the content; for example, a youtube watch link returns a YoutubeScraper, a Facebook fanpage link returns a FacebookScraper and so on. Should I use the factory pattern to do this? My idea is that the factory has one public method. It takes a String argument representing a link, and returns a suitable implementation of the Scraper interface. I guess the Factory would hold a list of Scraper implementations, and would match the link against each Scraper until it finds a suitable one. If there is no suitable one, it throws an Exception instead.

  • How to get the current project directory or the bin directory and move a few level up?

    - by melaos
    I have an ASP.Net MVC app, and i have some xsl files inside of the Content directory. I've try a few methods to get directory dynamically buy keep on coming short. So how do i get the directory to point to the Content/xsl folder? the closest that i came to was with this: this.GetType().Assembly.CodeBase which only returns the project DLL, but i can't figure out how to move up a few levels from there or what .net library to use to navigate around the path. there's no ../.. :( Basically i want to navigate to the Content/xsl folder which is at the same level of the Bin directory.

  • Adding text before footer in wordpress

    - by jake
    I've been reading the wordpress codex and it seems that if I want to add some text just before the footer shows up I should use code like this in my functions.php add_action('wp_footer', 'your_function'); function your_function() { $content = 'This is inserted at the bottom'; echo $content; } It is my understanding that the $content should show up just before the footer, but it does not show up at all. Is there another way to show up my code just before the footer ? I am with WP 2.8 but this should not matter

  • Drupal join on taxonomy terms

    - by ciscoheat
    I have a Drupal setup like this: Content type: Apartments Vocabulary: Areas, that can be used with Apartments. Content type: User profile, with a Content Taxonomy Field for Areas so users can select what areas they are interested in. I would like a view that shows all the user profiles that matches the apartments in their area. A "User profile <- Areas <- Apartments" join in other words. I've been mucking around with the views interface for a while but it's not clear to me how the relations can be setup to achieve this. Can someone give me a hint? In case this cannot be easily solved with views, what is a good way of doing it otherwise? Thanks for your help.

  • PHP / jQuery page change transition

    - by Tim
    Hey all Basically I want to replicate the page changing effect found here, at http://timvandamme.com/ But instead of using #values I want to use PHP includes, mainly because I want the site to be as uber-seo-friendly as possible... but still have this nice effect. So is there a way of doing this? I have a main index file which includes other php files in the centre using the usual 'GET' method, so my pages look like: "index.php?page=about" In my jQuery code I want to have a declaration where if I click the navigation, the content scrolls up, then once the relevant PHP file has loaded, have the content scroll back down and show the new page content (whilst also of navigated to the new page in the address bar, so if the user clicks the back button in their browser, they return to the previous page). I know how to code the scrolling bits, it's just literally the ajax loading includes / page navigation parts I'm struggling to work out :\ Any help would be MUCH appreciated!!! Thanks in advance.

  • How can I force asp.net webapi to always decode POST data as JSON

    - by Nathan Reed
    I getting some json data posted to my asp.net webapi, but the post parameter is always coming up null - the data is not being serialized correctly. The method looks something like this: public HttpResponseMessage Post(string id, RegistrationData registerData) It seems the problem is that the client (which I have no control over) is always sending the content-type as x-www-form-urlencoded, even though the content is actually json. This causes mvc to try to deserialize as form data, which fails. Is there anyway to get webapi to always deserialize as json, and to ignore the content-type header?

  • Efficiently making web pages from multiple servers

    - by james.bcn
    I want to create a service that allows diverse web site owners to integrate material from my web servers into content served from their own servers. Ideally the resulting web page would only be delivered from the web site owners server, and the included content would be viewed as being part of the site by Google - which I think would rule out iframes or client-side Javascript to get the content from my server (although I may be wrong about that?). Also the data wouldn't actually be updated that often, say once a day, so it would be inefficient to get the data from my web servers with every request. Finally, the method needs to be as simple as possible so that it is easy for web site owners to integrate into their own sites. Are there any good methods for doing this sort of thing? If not then I guess the simple way is with iframes or Javascript.

  • C code autocomplete in Eclipse

    - by Ittai
    Hi, I'm a Java developer and I've downloaded the Eclipse for C (course purposes) and to my amazement the control+space shortcut (for autocomplete) did not work. I've created a new project and a new class using the wizzards and started to type "print" and then tried to find an autocomplete feature. After a bit of googling I arrived at C/C++-Editor-Content Assist-Advanced and there I verified that Help proposals,Parsing-based proposals and Template proposals options were checked. I then went over to the Keys preferences page using the link at that page and entered a binding for all relevant content assist from before C\C++ Content Assist (type...) and chose in the When box the C\C++ Editor option. But alas no autocompletion was offered. Can someone please point me to the right direction? Thanks, Ittai

  • Using CSS, how can I make overflow:visible; contents overlap adjacent <td> cells?

    - by Structure
    I have the following CSS style code for my table: td { overflow: hidden; white-space:nowrap; } td:hover { overflow: visible; } However, when I hover over a <td> element whos contents (text) are hidden, the result is that the contents become visible but are behind the content of the adjacent cell (right side). I do not think that z-index can be applied to table cell elements, so is there a CSS attribute that I can specify within my td:hover style which will make the content of my <td> tag overlap the content in adjacent cells?

  • Flash not interacting with Javascripts in browser inside my app

    - by Shivaprasad
    Hi , I have an application which embeds a xulrunner based browser. I have to load some flash content in it which talks to some javascripts to update the browser title. The flash content works fine when launched from Firefox but not inside my app. I tried a sample html file which has some javascripts and they work fine. It even works when I have the flash content on a server. It is only when I try to run js through flash present on my local machine that I see this problem. I guess it must have something to do with some security settings in xulrunner. Could somebody help me figure out what the problem might be? Thanks jbsp72

  • What is the proper way to resolve Eclipse warning "isn't parameterized"?

    - by Morinar
    I'm trying to clean up some warnings in some old Java code (in Eclipse), and I'm unsure what the proper thing to do is in this case. The block looks more or less like this: Transferable content = getToolkit().getSystemClipboard().getContents( null ); java.util.List clipboardFileList = null; if( content.isDataFlavorSupported( DataFlavor.javaFileListFlavor ) ) { try { clipboardFileList = (java.util.List)content.getTransferData( DataFlavor.javaFileListFlavor); } /* Do other crap, etc. */ } The List generates a warning as it isn't parameterized, however, if I parameterize it with <File>, which I'm pretty sure is what it requires, it complains that it can't convert from Object to List<File>. I could merely suppress the unchecked warning for the function, but would prefer to avoid that if there is a "good" solution. Thoughts?

  • Android application chrashes after "share" intent

    - by Johe Green
    Hi, My app offers a "share/tell-a-friend" function. When the "share" button is pressed the following method is being called to open a list of apps, which can perform the action (Eg. Gmail, Twittroid, Facebook...): public void share() { Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.menu_share_subject)); shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getText(R.string.menu_share_body)); startActivity(Intent.createChooser(shareIntent, getText(R.string.menu_share_intent))); } The sharing functionality works basically. But when the sharing app (Facebook, Twitter, ...) tries to return to my app, a force close is thrown. I guess that my app gets closed in the background during the sharing process... at least that is what the debugger sais... Any ideas?

  • Bind multiple request parameters to one object in Spring 3

    - by Max
    Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

  • Django model field value preprocessing before returning

    Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

  • SQL Server Table Polling by Multiple Subscribers

    - by Daniel Hester
    Background Designing Stored Procedures that are safe for multiple subscribers (to call simultaneously) can be challenging.  For example let’s say that you want multiple worker processes to poll a shared work queue that’s encapsulated as a SQL Table. This is a common scenario and through experience you’ll find that you want to use Table Hints to prevent unwanted locking when performing simultaneous queries on the same table. There are three table hints to consider: NOLOCK, READPAST and UPDLOCK. Both NOLOCK and READPAST table hints allow you to SELECT from a table without placing a LOCK on that table. However, SELECTs with the READPAST hint will ignore any records that are locked due to being updated/inserted (or otherwise “dirty”), whereas a SELECT with NOLOCK ignores all locks including dirty reads. For the initial update of the flag (that marks the record as available for subscription) I don’t use the NOLOCK Table Hint because I want to be sensitive to the “active” records in the table and I want to exclude them.  I use an Update Lock (UPDLOCK) in conjunction with a WHERE clause that uses a sub-select with a READPAST Table Hint in order to explicitly lock the records I’m updating (UPDLOCK) but not place a lock on the table when selecting the records that I’m going to update (READPAST). UPDATES should be allowed to lock the rows affected because we’re probably changing a flag on a record so that it is not included in a SELECT from another subscriber. On the UPDATE statement we should explicitly use the UPDLOCK to guard against lock escalation. A SELECT to check for the next record(s) to process can result in a shared read lock being held by more than one subscriber polling the shared work queue (SQL table). It is expected that more than one worker process (or server) might try to process the same new record(s) at the same time. When each process then tries to obtain the update lock, none of them can because another process has a shared read lock in place. Thus without the UPDLOCK hint the result would be a lock escalation deadlock; however with the UPDLOCK hint this condition is mitigated against. Note that using the READPAST table hint requires that you also set the ISOLATION LEVEL of the transaction to be READ COMMITTED (rather than the default of SERIALIZABLE). Guidance In the Stored Procedure that returns records to the multiple subscribers: Perform the UPDATE first. Change the flag that makes the record available to subscribers.  Additionally, you may want to update a LastUpdated datetime field in order to be able to check for records that “got stuck” in an intermediate state or for other auditing purposes. In the UPDATE statement use the (UPDLOCK) Table Hint on the UPDATE statement to prevent lock escalation. In the UPDATE statement also use a WHERE Clause that uses a sub-select with a (READPAST) Table Hint to select the records that you’re going to update. In the UPDATE statement use the OUTPUT clause in conjunction with a Temporary Table to isolate the record(s) that you’ve just updated and intend to return to the subscriber. This is the fastest way to update the record(s) and to get the records’ identifiers within the same operation. Finally do a set-based SELECT on the main Table (using the Temporary Table to identify the records in the set) with either a READPAST or NOLOCK table hint.  Use NOLOCK if there are other processes (besides the multiple subscribers) that might be changing the data that you want to return to the multiple subscribers; or use READPAST if you're sure there are no other processes (besides the multiple subscribers) that might be updating column data in the table for other purposes (e.g. changes to a person’s last name).  NOLOCK is generally the better fit in this part of the scenario. See the following as an example: CREATE PROCEDURE [dbo].[usp_NewCustomersSelect] AS BEGIN -- OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON -- DECLARE TEMP TABLE -- Note that this example uses CustomerId as an identifier; -- you could just use the Identity column Id if that’s all you need. DECLARE @CustomersTempTable TABLE ( CustomerId NVARCHAR(255) ) -- PERFORM UPDATE FIRST -- [Customers] is the name of the table -- [Id] is the Identity Column on the table -- [CustomerId] is the business document key used to identify the -- record globally, i.e. in other systems or across SQL tables -- [Status] is INT or BIT field (if the status is a binary state) -- [LastUpdated] is a datetime field used to record the time of the -- last update UPDATE [Customers] WITH (UPDLOCK) SET [Status] = 1, [LastUpdated] = GETDATE() OUTPUT [INSERTED].[CustomerId] INTO @CustomersTempTable WHERE ([Id] = (SELECT TOP 100 [Id] FROM [Customers] WITH (READPAST) WHERE ([Status] = 0) ORDER BY [Id] ASC)) -- PERFORM SELECT FROM ENTITY TABLE SELECT [C].[CustomerId], [C].[FirstName], [C].[LastName], [C].[Address1], [C].[Address2], [C].[City], [C].[State], [C].[Zip], [C].[ShippingMethod], [C].[Id] FROM [Customers] AS [C] WITH (NOLOCK), @CustomersTempTable AS [TEMP] WHERE ([C].[CustomerId] = [TEMP].[CustomerId]) END In a system that has been designed to have multiple status values for records that need to be processed in the Work Queue it is necessary to have a “Watch Dog” process by which “stale” records in intermediate states (such as “In Progress”) are detected, i.e. a [Status] of 0 = New or Unprocessed; a [Status] of 1 = In Progress; a [Status] of 2 = Processed; etc.. Thus, if you have a business rule that states that the application should only process new records if all of the old records have been processed successfully (or marked as an error), then it will be necessary to build a monitoring process to detect stalled or stale records in the Work Queue, hence the use of the LastUpdated column in the example above. The Status field along with the LastUpdated field can be used as the criteria to detect stalled / stale records. It is possible to put this watchdog logic into the stored procedure above, but I would recommend making it a separate monitoring function. In writing the stored procedure that checks for stale records I would recommend using the same kind of lock semantics as suggested above. The example below looks for records that have been in the “In Progress” state ([Status] = 1) for greater than 60 seconds: CREATE PROCEDURE [dbo].[usp_NewCustomersWatchDog] AS BEGIN -- TO OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON DECLARE @MaxWait int; SET @MaxWait = 60 IF EXISTS (SELECT 1 FROM [dbo].[Customers] WITH (READPAST) WHERE ([Status] = 1) AND (DATEDIFF(s, [LastUpdated], GETDATE()) > @MaxWait)) BEGIN SELECT 1 AS [IsWatchDogError] END ELSE BEGIN SELECT 0 AS [IsWatchDogError] END END Downloads The zip file below contains two SQL scripts: one to create a sample database with the above stored procedures and one to populate the sample database with 10,000 sample records.  I am very grateful to Red-Gate software for their excellent SQL Data Generator tool which enabled me to create these sample records in no time at all.

    - by Jhonghee
    I am having some problem understanding layouts in JavaFX. Consider following code. Stage { title: "ListView test" scene: Scene { width: 400 height: 400 content: [ VBox { content: [ ListView { height: 200 width: 200 items: ["item1", "item2"] } ] } ] } } I was expecting ListView showing up in 200 x 200 dimension but no matter how I tried to fix this, the width and height of ListView seemed fixed. But following code works for showing ListView as I intended. Stage { title: "ListView test" scene: Scene { width: 400 height: 400 content: [ ListView { height: 200 width: 200 items: ["item1", "item2"] } ] } } So, what is the problem here? I cannot use ListView within layouts?
