  • How can I get all content within <td> tag using a HTML Agility Pack?

    - by Bob Dylan
    So I'm writing an application that will do a little screen scrapping. I'm using the HTML Agility Pack to load an entire HTML page into an instance of HtmlDocoument called doc. Now I want to parse that doc, looking for this: <table border="0" cellspacing="3"> <tr><td>First rows stuff</td></tr> <tr> <td> The data I want is in here <br /> and it's seperated by these annoying <br /> 's. No id's, classes, or even a single <p> tag. </p> Just a bunch of <br /> tags. </td> </tr> </table> So I just need to get the data within the 2nd row. How can I do this? Should I use a regex or something else?

  • How do I select elements based on all their content in jQuery?

    - by Kev
    I have a series of <div/>'s as follows: <div>.co.uk</div> <div>.com</div> <div>.gb.com</div> <div>.uk.com</div> <div>.net</div> How do I select just the divs containing .co.uk, .com, .net. If I use: $('div:contains(".co.uk"), div:contains(".com"), div:contains(".net")`) This causes the .gb.com and .uk.com divs to be selected as well.

  • For programming content, what simple-to-use-and-setup PHP based blog are the preferred ones?

    - by Johann Gerell
    I've since long wanted a place I can toss my programming related nuggets at. Every day I feel I solve something that I'll surely hit again in a not so distant future, but by then I most certainly will have forgotten about the previous solution I came up with. So I need to blog it down, quick and dirty, for my own documentation and memory's sake. Must be easy to set up and use. Must handle code syntax and highlighting gracefully for a number of languages, but mainly C# and C++. Must be PHP-based, because that's what my host supplies. I know and have used WordPress (not for code, though), but is it really what I want or need?

  • Designing a silverlight dashboard with mef - is it possible? (with dynamic loading of xaps)

    - by Tim Robbin
    Hello! I am just trying to wrap my head around MEF. And as I am really going to love it ( I guess ) I started my first sample project and immediatly stumbled into a big problem and now I am asking myself if I can use MEF for my scenario at all and that is the following: Imagine that one got some kind of dashboard with, let's say, five regions and above each region there are two comboboxes. The values in the first combobox represent different possible views (for example, chartControl, tableControl, pictureControl, ...) and the values of the second combobox represents the different data sources for the currently selected control. As the controls are very big in size one wants to download them as needed. If the user selects one comboboxitem the corresponding control xap should be loaded and displayed in this specific region. If the user selectes another control in the same combobox the control should be removed from the visualtree and the next control should be downloaded and displayed. If the user changes the selection in a different combobox the corresponding control should be loaded again only in this specific region, with perhaps different data. And to make it a little more interesting - as this is some kind of dashboard one can change the layout from five regions to - for example - ten regions. I've seen the video "MVVM with MEF in Silverlight Video Tutorial Part 2: Plugins and Metadata" ( http://csharperimage.jeremylikness.com/2010/03/mvvm-with-mef-in-silverlight-video_09.html ) but he is using an ItemsControl and is working with Visibility and he only got ONE region. So I think that this technique is not working for me... Puh, I hope I could make myself clear! Thanks a lot for any piece of information!!! Greetings, Tim.

  • How to access controller dynamic properties within a base controller's constructor in Grails?

    - by 4h34d
    Basically, I want to be able to assign objects created within filters to members in a base controller from which every controller extends. Any possible way to do that? Here's how I tried, but haven't got to make it work. What I'm trying to achieve is to have all my controllers extend a base controller. The base controller's constructor would be used to assign values to its members, those values being pulled from the session map. Example below. File grails-app/controllers/HomeController.groovy: class HomeController extends BaseController { def index = { render username } } File grails-app/controllers/BaseController.groovy: abstract class BaseController { public String username public BaseController() { username = session.username } } When running the app, the output shown is: 2010-06-15 18:17:16,671 [main] ERROR [localhost].[/webapp] - Exception sending context initialized event to listener instance of class org.codehaus.groovy.grails.web.context.GrailsContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pluginManager' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: Unable to locate constructor with Class parameter for class org.codehaus.groovy.grails.commons.DefaultGrailsControllerClass ... Caused by: java.lang.RuntimeException: Unable to locate constructor with Class parameter for class org.codehaus.groovy.grails.commons.DefaultGrailsControllerClass ... Caused by: java.lang.reflect.InvocationTargetException ... Caused by: org.codehaus.groovy.grails.exceptions.NewInstanceCreationException: Could not create a new instance of class [com.my.package.controller.HomeController]! ... Caused by: groovy.lang.MissingPropertyException: No such property: session for class: com.my.package.controller.HomeController at com.my.package.controller.BaseController.<init>(BaseController.groovy:16) at com.my.package.controller.HomeController.<init>(HomeController.groovy) ... 2010-06-15 18:17:16,687 [main] ERROR core.StandardContext - Error listenerStart 2010-06-15 18:17:16,687 [main] ERROR core.StandardContext - Context [/webapp] startup failed due to previous errors And the app won't run. This is just an example as in my case I wouldn't want to assign a username to a string value, but rather a few objects pulled from the session map. The objects pulled from the session map are being set within filters. The alternative I see is being able to access the controller's instance within the filter's execution. Is that possible? Please help! Thanks a bunch!

  • How to stop OpenGL from applying blending to certain content? (see pics)

    - by RexOnRoids
    Supporting Info: I use cocos2d to draw a sprite (graph background) on the screen (z:-1). I then use cocos2d to draw lines/points (z:0) on top of the background -- and make some calls to OpenGL blending functions before the drawing to SMOOTH out the lines. Problem: The problem is that: aside from producing smooth lines/points, calling these OpenGL blending functions seems to "degrade" the underlying sprite (graph background). As you can see from the images below, the "degraded" background seems to be made darker and less sharp in Case 2. So there is a tradeoff: I can either have (Case 1) a nice background and choppy lines/points, or I can have (Case 2) nice smooth lines/points and a degraded background. But obviously I need both. THE QUESTION: How do I set OpenGL so as to only apply the blending to the layer with the Lines/Points in it and thus leave the background alone? The Code: I have included code of the draw() method of the CCLayer for both cases explained above. As you can see, the code producing the difference between Case 1 and Case 2 seems to be 1 or 2 lines involving OpenGL Blending. Case 1 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Commenting out the following two lines induces a problem of making it impossible to have smooth lines/points, but has merit in that it does not degrade the background sprite.*/ //glEnable (GL_BLEND); //glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } } Case 2 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Enabling the following two lines gives nice smooth lines/points, but has a problem in that it degrades the background sprite.*/ glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } }

  • Is there any way to create a dynamic list of strings (based on language) in XAML?

    - by Xin
    Just wondering if it is possible to dynamically create a list of strings in XAML based on language/culture? Say if user logs in as an English user it shows Client Name, Order Number... and if user logs in as a Polish user it shows Nazwa klienta, Numer zamówienia instead? I only know the hardcoded one like below: <System_Collections_Generic:List`1 x:Key="columnNameList"> <System:String>Client Name</System:String> <System:String>Order Number</System:String> <System:String>Date</System:String> </System_Collections_Generic:List`1>

  • RDLC item width is dynamic and causing extra pages to be generated (image included)?

    - by Paul Mendoza
    I'm trying to format an RDLC report file in Visual Studio 2008 and I am having a formatting issue. I have a list at the bottom that contains a matrix that expands horizontally to the right. That pink box is just to visualize the problem I'm having. When the report is rendered the matrix expands and instead of filling the pink box with the matrix is pushes the space in the pink box to the right resulting in an extra page when printing the reports. One solution would be to shrink the pink box to be the size of the matrix which I've done. But then when the matrix grows the fields at the top of the report get pushed to the right by the same amount as the growth of the matrix. Can someone please let me know what they think the solution would be? Thank you!

  • Action Mailer: How do I render dynamic data in an email body that is stored in the database?

    - by Brandon Toone
    I have Action Mailer setup to render an email using the body attribute of my Email model (in the database). I want to be able to use erb in the body but I can't figure out how to get it to render in the sent email message. I'm able to get the body as a string with this code # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # pulls the email body and passes a string to the template views/user_mailer/customer_email.text.html.erb body :msg => email.body end I came across this article http://rails-nutshell.labs.oreilly.com/ch05.html which says I can use render but I'm only able to get render :text to work and not render :inline # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # body :msg => email.body body :msg => (render :text => "Thanks for your order") # renders text and passes as a variable to the template # body :msg => (render :inline => "We shipped <%= Time.now %>") # throws a NoMethodError end

  • dynamic grid style form that lets you update multiple rows in a single post in asp.net mvc

    - by Charlie Bear
    I'm starting out with MVC but not sure it's the best option. I need to create a form that is based upon a collection. Eg it might look like this: product Price Item 1 [textbox] Item 2 [textbox] [submit button] where "item" is pulled from the database and textbox allows users to update the price. essentially this is a type of datagrid but i don't want webforms style update each row one at a time i need to update the entire set of text boxes in one post. Ideally I don't want a javascript based solution as it has to work without javascript. Is this possible in MVC or should I stick to webforms (where I could do this in a repeater by iterating through he repeater items on postback)

  • How to display an array's content in colomns, like ls -C does.

    - by Arko
    I wanted to display a long list of strings from an array. Right now, my script run through a for loop echoing each value to the standard output: for value in ${values[@]} do echo $value done Yeah, that's pretty ugly! And the one column listing is pretty long too... I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).

  • How to handle dynamic role or username changes in JSF?

    - by roadrunner
    I have a JSF application running on glassfish 2.1 with a EJB 3 backend. For authentication I use a custom realm. The user authenticates using the e-mail-address and password he specified on registration. Everything is working quite well. Now I have two related problems: 1) The user can edit his profile and -- naturally -- he can also change his e-mail-address. Unfortunately when I perform operations based on the current user's identity using ExternalContext.getUserPrincipal().getName(), I will receive the previous e-mail-address the user used on login. At the moment I handle this by forcing the user to reauthenticate after he changed his e-mail-address, but is there another more graceful possibility? 2) Same for user roles. E.g. I have the user roles MEMBER and PREMIUM_MEMBER. A MEMBER may become a PREMIUM_MEMBER during his current session. Unfortunately the role seems to be only determined at login. Is there any possibility, that JSF and EJB recognize the new user role without the need for the user to re-authenticated?

  • dynamic html "more information" callout / annotation (jquery? ajax control toolkit?)

    - by nailitdown
    Hola, I have an app i'm building in c#, and i'd like to have the ability to have a user click a "more information" icon next to a field, which will then show a callout with some blurb about why the field contains what it does. ideally it'd look a lot like the ValidatorCallout, but instead of being shown as a result of validation, it'll be shown as a result of a mouseclick, or hover. Anyone know of a nice way to do this with either the ajaxcontroltoolkit, or jquery? cheers for any help you can give me.

  • How can I handle dynamic calculated attributes in a model in Django?

    - by bullfish
    In Django I calculate the breadcrumb (a list of fathers) for an geographical object. Since it is not going to change very often, I am thinking of pre calculating it once the object is saved or initialized. 1.) What would be better? Which solution would have a better performance? To calculate it at _init_ or to calculate it when the object is saved (the object takes about 500-2000 characters in the DB)? 2.) I tried to overwrite the _init_ or save() methods but I don't know how to use attributes of the just saved object. Accessing *args, **kwargs did not work. How can I access them? Do I have to save, access the father and then save again? 3.) If I decide to save the breadcrumb. Whats the best way to do it? I used http://www.djangosnippets.org/snippets/1694/ and have crumb = PickledObjectField(). Thats the method to calculate the attribute crumb() def _breadcrumb(self): breadcrumb = [ ] x = self while True: x = x.father try: if hasattr(x, 'country'): breadcrumb.append(x.country) elif hasattr(x, 'region'): breadcrumb.append(x.region) elif hasattr(x, 'city'): breadcrumb.append(x.city) else: break except: break breadcrumb.reverse() return breadcrumb Thats my save-Method: def save(self,*args, **kwargs): # how can I access the father ob the object? father = self.father # does obviously not work father = kwargs['father'] # does not work either # the breadcrumb gets calculated here self.crumb = self._breadcrumb(father) super(GeoObject, self).save(*args,**kwargs) Please help me out. I am working on this for days now. Thank you.

  • Regex in Flex 3: How to Wrap Quotations Around a Dynamic String?

    - by Laxmidi
    Hi, I need some Regex help. I need to find beacon_ followed by an alphanumeric code and then wrap it in quotation marks. For something static, like the example, below it's straight forward. myReturn = myReturn.replace( 'id=beacon_80291ee9b3', 'id="beacon_80291ee9b3"'); But, my problem is that the part after beacon is a random alphanumeric code. (However, it is always the same length). For example, the beacon part could be: beacon_c8ac873136 beacon_dc83b5953e beacon_7a910d03d8 etc. The haystack that I'll search will look like: myReturn = "blah blah id=beacon_80291ee9b3 blah blah"; Thanks. -Laxmidi

  • How do I view the full content of a text or varchar(MAX) column in SQL Server 2008 Management Studio

    - by adamjford
    In this live SQL Server 2008 (build 10.0.1600) database, there's an Events table, which contains a text column named Details. (Yes, I realize this should actually be a varchar(MAX) column, but whoever set this database up did not do it that way.) This column contains very large logs of exceptions and associated JSON data that I'm trying to access through SQL Server Management Studio, but whenever I copy the results from the grid to a text editor, it truncates it at 43679 characters. I've read on various locations on the Internet that you can set your Maximum Characters Retrieved for XML Data in Tools > Options > Query Results > SQL Server > Results To Grid to Unlimited, and then perform a query such as this: select Convert(xml, Details) from Events where EventID = 13920 (Note that the data is column is not XML at all. CONVERTing the column to XML is merely a workaround I found from Googling that someone else has used to get around the limit SSMS has from retrieving data from a text or varchar(MAX) column.) However, after setting the option above, running the query, and clicking on the link in the result, I still get the following error: Unable to show XML. The following error happened: Unexpected end of file has occurred. Line 5, position 220160. One solution is to increase the number of characters retrieved from the server for XML data. To change this setting, on the Tools menu, click Options. So, any idea on how to access this data? Would converting the column to varchar(MAX) fix my woes?

  • How Can I ReWrite flat link to a dynamic link and preserve the Query string?

    - by jeremysawesome
    Hello All, I am wanting to rewrite a url like: http://my.project/mydomain.com/ANY_NUMBER_OF_CATEGORIES/designer/4/designer-name/page.html to this: http://my.projects/mydomain.com/ANY_NUMBER_OF_CATEGORIES/page.html?designer=4 I would like to use mod-rewrite to accomplish this. Things to note: Any number of categories can be between 'mydomain.com/' and '/designer'. For instance the url could be http://my.project/mydomain.com/designer/4/designer-name/page.html or it could be http://my.project/mydomain.com/tops/shirts/small/designer/4/designer-name/page.html A query string may be provided in the original url that needs to be preserved in the rewritten url. For example url provided could be: http://my.project/mydomain.com/designer/4/designer-name/page.html?color=red&type=shirt Given the url above the resulting url would need to be: http://my.projects/mydomain.com/page.html?designer=4&color=red&type=shirt The order of the query string does not matter. The 'designer=4' part could come before or after the rest of the query string. I'm new to .htaccess and re-writes so any examples and or explanations would be greatly appreciated. Thank you very much.
