• Script to copy files on CD and not on hard disk to a new directory

  - by John22

  I need to copy files from a set of CDs that have a lot of duplicate content, with each other, and with what's already on my hard disk. The file names of identical files are not the same, and are in sub-directories of different names. I want to copy non-duplicate files from the CD into a new directory on the hard disk. I don't care about the sub-directories - I will sort it out later - I just want the unique files. I can't find software to do that - see my post at SuperUser http://superuser.com/questions/129944/software-to-copy-non-duplicate-files-from-cd-dvd Someone at SuperUser suggested I write a script using GNU's "find" and the Win32 version of some checksum tools. I glanced at that, and have not done anything like that before. I'm hoping something exists that I can modify. I found a good program to delete duplicates, Duplicate Cleaner (it compares checksums), but it won't help me here, as I'd have to copy all the CDs to disk, and each is probably about 80% duplicates, and I don't have room to do that - I'd have to cycle through a few at a time copying everything, then turning around and deleting 80% of it, working the hard drive a lot. Thanks for any help.

• SharePoint Designer Workflow: Unruly 'Collect User Data' Action

  - by Jeremy

  I'm a student in a SharePoint class online. This problem has riddled everyone I've discussed it with, including the teacher. There seems to be some sort of problem when I create a workflow with the collect data action. I can create workflows that send e-mails and use the other actions just fine. What could be causing this problem? My reproduction steps are simple: Create a new Site Collection with the Blank Site template. Create a new Custom List. In SharePoint Designer, start a new workflow on the Custom List. Add the collect data action to the workflow. Set the user to the one that created the task. Set the data to anything. A single check box, a string, Choice, doesn't matter. Leave the output variable as default. Mystery error appears! When the Check Workflow button is pressed, nothing happens. No message box appears at all. The warning icon in the Steps panel merely points out that there are some errors, it isn't specific as to what they are. Additionally, when I click on the data object again after it's been created, it doesn't populate the form with the old values. It goes back to the default name with no fields. So there's definitely something going wrong here. I've narrowed the problem down to the data object, but I don't know what to do about it. The workflow acts like normal for other activities. For example, delete the Collect Data action and add a Send Email one instead and it compiles and runs successfully.

• Setting objects (not users) inactive after period of time in asp.net mvc

  - by bastijn

  This question is mainly to verify my current idea. I have a series of objects which I want to be active for a specified amount of time. For instance objects like ads which are shown in the ad space only for the amount of time bought, objects in search results which should only pop up when active, and frontpage posts which should be set to inactive after a prespecified time. My current idea is to just give those type of objects a StartDate and EndDate and filter the search routines to only show results which fall in the range StartDate < currentDate < EndDate. Is this the normal structure or should there be some sort of auto-routine which routinely checks for objects which are "over-time" and set a property "inactive" to true or something. Seems like this approach is such a hassle since I need a checker which runs say, every 5 minutes, to scan all DB objects. Seems like a bad idea to me. So is the first structure the most commonly used or are there any other options? When searching on google or SO the search queries only return results setting users inactive.

• Windows Form color changing

  - by Sef

  Hello, So i am attempting to make a MasterMind program as sort of exercise. Field of 40 picture boxes (line of 4, 10 rows) 6 buttons (red, green, orange, yellow, blue, purple) When i press one of these buttons (lets assume the red one) then a picture box turns red. My question is how do i iterate trough all these picture boxes? I can get it to work but only if i write : And this is offcourse no way to write this, would take me countless of lines that contain basicly the same. private void picRood_Click(object sender, EventArgs e) { UpdateDisplay(); pb1.BackColor = System.Drawing.Color.Red; } Press the red button - first picture box turns red Press the blue button - second picture box turns blue Press the orange button - third picture box turns orange And so on... Ive had a previous similar program that simulates a traffic light, there i could assign a value to each color (red 0, orange 1, green 2). Is something similar needed or how exactly do i adress all those picture boxes and make them correspond to the proper button. Best Regards.

• Control Oracle Forms with outside program

  - by user256893

  I work at a company that uses the Forms based Oracle 11i. A lot of employees complain of the redundancy of data entry and I want to write a program that will ease some of that pain since all attempts to ask IT to do it have failed. The problem is, since Oracle Forms are Java based there are no "controls" as there would be on say a windows application or an HTML based form. Does anyone know of a way to tell the PC to (example only) click edit field 3 on the RMA creation form and then enter the data? The only way I can programmatically navigate Oracle is with hotkeys and it's very unreliable. I'm not concerned about the language or learning a new application to resolve this issue. I currently know (elementary to Intermediate levels) Java, VB.NET and will be taking C++ in school. Is there a tool, bridge, element spy of some sort that will allow me to send commands to elements on the forms? edit APC sez: Oracle Forms over the web run as a Java applet. I mention this because it may be relevant to your responses.

• As a newbie, where should I go if I want to create a small GUI program?

  - by jimbmk

  Hello, I'm a newbie with a little experience writing in BASIC, Python and, of all things, a smidgeon of assembler (as part of a videogame ROM hack). I wanted to create small tool for modifying the hex values at particular points, in a particular file, that would have a GUI interface. What I'm looking for is the ability to create small GUI program, that I can distribute as an EXE (or, at least a standalone directory). I'm not keen on the idea of the .NET languages, because I don't want to force people to download a massive .NET framework package. I currently have Python with IDLE and Boa Constructor set up, and the application runs there. I've tried looking up information on compiling a python app that relies on Wxwidgets, but the search results and the information I've found has been confusing, or just completely incomprehensible. My questions are: Is python a good language to use for this sort of project? If I use Py2Exe, will WxWidgets already be included? Or will my users have to somehow install WxWidgets on their machines? Am I right in thinking at Py2Exe just produces a standalone directory, 'dist', that has the necessary files for the user to just double click and run the application? If the program just relies upon Tkinter for GUI stuff, will that be included in the EXE Py2Exe produces? If so, are their any 'visual' GUI builders / IDEs for Python with only Tkinter? Thankyou for your time, JBMK

• Embedding/deploying custom font in .NET app

  - by Swingline Rage

  Is there an official way to distribute (deploy) a specific font with a .NET application? We have a (public domain) "LED font" that prints numbers with the retro LED instrumentface look. This is a standard True Type or Open Type font like any other except it looks funky. Obviously for that to work, this font needs to be on the user's machine. But we'd prefer to not force the user to "install our special font into your font folder". We'd prefer to either load a Font object directly from the TTF, or programatically install the font so it's available. How do applications handle this sort of things? Eg, I notice Adobe XYZ installs various fonts on the system without user intervention. That's what we'd like to do. EDIT: okay, ideally, we'd prefer not to install the font directly. We don't want our nifty themed LED font showing up in the user's font dropdown in MS Word. We'd prefer to use this font, but restrict its use or appearance to our app. Any way to do this? Thanks!

• Java Generic Casting Type Mismatch

  - by Kay

  public class MaxHeap<T extends Comparable<T>> implements Heap<T>{ private T[] heap; private int lastIndex; public void main(String[] args){ int i; T[] arr = {1,3,4,5,2}; //ERROR HERE ******* foo } public T[] Heapsort(T[]anArray, int n){ // build initial heap T[]sortedArray = anArray; for (int i = n-1; i< 0; i--){ //assert: the tree rooted at index is a semiheap heapRebuild(anArray, i, n); //assert: the tree rooted at index is a heap } //sort the heap array int last = n-1; //invariant: Array[0..last] is a heap, //Array[last+1..n-1] is sorted for (int j=1; j<n-1;j++) { sortedArray[0]=sortedArray[last]; last--; heapRebuild(anArray, 0, last); } return sortedArray; } protected void heapRebuild(T[ ] items, int root, int size){ foo } } The error is on the line with "T[arr] = {1,3,4,5,2}" Eclispe complains that there is a: "Type mismatch: cannot convert from int to T" I've tried to casting nearly everywhere but to no avail.A simple way out would be to not use generics but instead just ints but that's sadly not an option. I've got to find a way to resolve the array of ints "{1,3,4,5,2}" into an array of T so that the rest of my code will work smoothly.

• Going from small to medium sized websites.

  - by Landitus

  I've been coding websites for a couple of years now, mostly in php and xhtml. I come from the design world, but I'm proud of doing standart compliant websites and great interfaces. Also used Wordpress and loved it. Most of the time there were really simple commercial websites, with no database included, where everything is done from scratch. Every page is parsed through an index?page=xxx and But I have a few prospects that are larger websites (let's call them 'medium sized websites') where I feel I'm lacking the following: How to dispach or render the pages (MVC controller instead of index?page=???) Proper page hierarchy and easy breadcrumbs implementation Auto generation of navigation menu, or an easy way to maintain them? Clean URLs Form validation Easy database support I really don't know if I should be looking into php scripts, and refine my skills or get into a CMS (like drupal) or a PHP framework. I found Wordpress very assuring and didn't feel trapped into crazy conventions, but I feel is not the right tool for this. I hate the CMS Page with the big textbox as I am used to code every page by hand my pages are not a title and a textbox. Got the feeling? My php skills are sort of medium/low still, but I would like to hear some thoughts of what I should learn to take the next step!

• cannot override a concrete member without a third member that's overridden by both

  - by huynhjl

  What does the following error message mean? cannot override a concrete member without a third member that's overridden by both (this rule is designed to prevent ``accidental overrides''); I was trying to do stackable trait modifications. It's a little bit after the fact since I already have a hierarchy in place and I'm trying to modify the behavior without having to rewrite a lot of code. I have a base class called AbstractProcessor that defines an abstract method sort of like this: class AbstractProcessor { def onPush(i:Info): Unit } I have a couple existing traits, to implement different onPush behaviors. trait Pass1 { def onPush(i:Info): Unit = { ... } } trait Pass2 { def onPush(i:Info): Unit = { ... } } So that allows me to use new AbstractProcessor with Pass1 or new AbstractProcessor with Pass2. Now I would like to do some processing before and after the onPush call in Pass1 and Pass2 while minimizing code changes to AbstractProcessor and Pass1 and Pass2. I thought of creating a trait that does something like this: trait Custom extends AbstractProcessor { abstract override def onPush(i:Info): Unit = { // do stuff before super.onPush(i) // do stuff after } And using it with new AbstractProcessor with Pass1 with Custom and I got that error message.

• JPA/Hibernate query with class name?

  - by Petteri Hietavirta

  In this example com.test.Cat extends com.test.Animal and there is no field DB in CAT table of com.test.Cat explicitly defining its type (it wasn't me). When I query my animals from DB I get a collection of Animals. It is possible to sort them by class name: order by r.class but is there a way to use class name as a criteria? For example I would like to get all animals expect dogs. But no luck - even this does not work: where r.class = ?

• How to safely let users submit custom themes/plugins for a Rails app

  - by Brian Armstrong

  In my rails app I'd like to let users submit custom "themes" to display data in various ways. I think they can get the data in the view using API calls and I can create an authentication mechanism for this. Also an authenticated API to save data. So this is probably safe. But i'm struggling with the best way to let users upload/submit their own code for the theme. I want this to work sort of like Wordpress themes/plugins where people can upload the thing. But there are some security risks. For example, if I take the uploaded "theme" a user submits and put it in it's own directory somewhere inside the rails app, what are the risks of this? If the user inserts any rails executable code in their theme, even though it's the view they have full access at that point to all the models, everyone's data, etc. Even from other users. So that is not good. I need some way to let the uploaded themes exist in a sandbox of the rails app, but I haven't seen a good way to do this. Any ideas?

• Dependency injection and factory

  - by legenden

  Trying to figure out how to best handle the following scenario: Assume a RequestContext class which has a dependency to an external service, such as: public class RequestContext : IRequestContext { private readonly ServiceFactory<IWeatherService> _weatherService; public RequestContext(ServiceFactory<IWeatherService> weatherService, UserLocation location, string query) { _weatherService = weatherService; ... What sort of dependency should I require in the class that will ultimately instantiate RequestContext? It could be ServiceFactory<IWeatherService>, but that doesn't seem right, or I could create an IRequestContextFactory for it along the lines of: public class RequestContextFactory : IRequestContextFactory { private readonly ServiceFactory<IWeatherService> _weatherService; public RequestContextFactory(ServiceFactory<IWeatherService> weatherService) { _weatherService = weatherService; } public RequestContext Create(UserLocation location, string query) { return new RequestContext(_weatherService, location, query); } } And then pass the IRequestContextFactory through constructor injection. This seems like a good way to do it, but the problem with this approach is that I think it hinders discoverability (devs must know about the factory and implement it, which is not really apparent). Is there a better/more discoverable way that I'm missing?

• Formatting Parameters for Ajax POST request to Rails Controller - for jQuery-UI sortable list

  - by Hung Luu

  I'm using the jQuery-UI Sortable Connected Lists. I'm saving the order of the connected lists to a Rails server. My approach is to grab the list ID, column ID and index position of each list item. I want to then wrap this into an object that can be passed as a parameter back to the Rails Controller to be saved into the database. So ideally i'm looking to format the parameter like this: Parameters: {"Activity"=>[{id:1,column:2,position:1},{id:2,column:2,position:2} ,...]} How do I properly format my parameters to be passed in this Ajax POST request? Right now, with the approach below, I'm passing on Parameters: {"undefined"=>""} This is my current jQuery code (Coffeescript) which doesn't work: jQuery -> $('[id*="day"]').sortable( connectWith: ".day" placeholder: "ui-state-highlight" update: (event, ui) -> neworder = new Array() $('[id*="day"] > li').each -> column = $(this).attr("id") index = ui.item.index() + 1 id = $("#" + column + " li:nth-child(" + index + ") ").attr('id') passObject={} passObject.id = id passObject.column = column passObject.index = index neworder.push(passObject) alert neworder $.ajax url: "sort" type: "POST" data: neworder ).disableSelection() My apologies because this seems like a really amateur question but I'm just getting started with programming jQuery and Javascript.

• Need events to execute on timer events, metronome precision.

  - by user295734

  I setup a timer to call an event in my application. The problme is the event execution is being skewed by other windows operations. Ex. openning and window, loading a webpage. I need the event to excute exactly on time, every time. When i first set up the app, used a sound file, like a metronome to listen to the even firing, in a steady state, its firing right on, but as soon do something in the windows environment, the sound fires slower, then sort of sppeds up a bit to catch up. So i added a logging method to the event to ctahc the timer ticks. From that data, it appears that the timer is not being affected by the windows app, but my application event calls are being affected. I figured this out by checking the datetime.now in the event, and if i set it to 250 milliseconds, which is 4 clicks per second. You get data something like below. (sec):(ms) 1:000 1:250 1:500 1:750 2:000 2:250 2:500 2:750 3:000 3:250 3:500 3:750 (lets say i execute some windows event)(time will skew) 4:122 4:388 4:600 4:876 (stop doing what i was doing in windows) (going to shorten the data for simplicit, my list was 30sec long) 5:124 5:268 5:500 5:750 (you would se the time go back the same milliseconds it was at the begining) 6:000 6:250 6:500 6:750 7:000 7:250 7:500 7:750 So i'm thinking the timer continues to fire on the same millisecond every time, but its the event that is being skewed to fire off time by other windows operations. Its not a huge skew, but for what i need to accomplish, its unacceptable. Is there anyhting i can do in .NET, hoping to use XAML/WPF application, thats will correct the skewing of events? thx.

• IList<Item> Collection Class accessing database

  - by Mike

  Hi, I have a database with Users. Users have Items. These Items can change actively. How do you access the items in a collection type format? For the user, I fill all the user properties at the time of instantiation. If I load the user's items at the time of the instantiation, and the items change, they will have old data. I was thinking, maybe I need an ItemCollection class and have that a field/property apart of the user class, that way to traverse all the user's items I could use a foreach loop. So, my question is, what is the best practice/best way of accessing the items from a database using some sort of collection? On accessing the particular Item, it needs to get the latest database information, and when the user does do a foreach loop, the latest item information must be available. I.e. What I'm trying to do Console.WriteLine(User.Items[3].ID); returns 5. //this updates the item information and saves it to the database. User.Items[3].ID = 13; //Add a new item to the database. User.Items.Add(new Item { id = 17}); foreach (Item item in User.Items) { //this would traverse all items in the database. //not some cached copy at the time of instantiation of the user. }

• Qt moc failure without an error message

  - by Robert Parker

  So I'm pretty new to Qt, and I've just inherited a project from someone else who is also new to Qt. He isn't around this week btw. We are using Visual Studio 2008, and have the latest version of Qt installed(4.6.2). The project builds on my coworker's machine fine, and I can get the project from svn and build it directly. But under any other circumstances it refuses to build on my machine, and it doesn't give me much of an explanation why. Even if I just do a 'build clean' and then a 'build' it doesn't work. Any slight modification will make it fail. When I try to build the entire project I get the error message: 1Moc'ing MatrixTypeInterface.h... 1moc: Cannot create .\GeneratedFiles\Debug\moc_MatrixTypeInterface.cpp;.\GeneratedFiles\Debug\moc_matrixtypeinterface.cpp 1Project : error PRJ0019: A tool returned an error code from "Moc'ing MatrixTypeInterface.h..." The moc tool doesn't give any sort of error message as to why it isn't working, and I wasted most of yesterday trying to figure out why. I got the command that VS was using to call moc, and I entered in the command line myself. It didn't write anything to the screen. Any ideas?

• Design pattern to keep track UITableView rows correspondance to underlying data in constant time.

  - by DenNukem

  When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. there is no ordering "key" that represents the sort order. There is also a corresponding UITableView that shows one row per addressbook entry. When UITableView queries the datasource I query the NSMUtableArray populated with my entries and return required data in constant time for each row. However, if there is a change in underlying model I am getting a notification "Joe Smith, id#123 has been removed". Now I have a dilemma. A naive approach would be to scan the array, determine the index at which Joe Smith is and then ask UITableView to remove that precise row from the view, also removing it form the array. However, the scan will take linear time to finish. Now I could have an NSDictionary which allows me to find Joe Smith in constant time, but that doesn't do me a lot of good because I still need to find his ordinal index within the array in order to instruct UITableView to remove that row, which is again a linear search. I could further decide to store each object's ordinal inside the object itself to make it constant, but it will become outdated after first such update as all subsequent index values will have changed due to removal of an object. So what is the correct design pattern to accurately reflect model changes in the UITableView in costant (or at least logarithmic) time?

• 4.0/WCF: Best approach for bi-idirectional message bus?

  - by TomTom

  Just a technology update, now that .NET 4.0 is out. I write an application that communicates to the server through what is basically a message bus (instead of method calls). This is based on the internal architecture of the application (which is multi threaded, passing the messages around). There are a limited number of messages to go from the client to the server, quite a lot more from the server to the client. Most of those can be handled via a separate specialized mechanism, but at the end we talk of possibly 10-100 small messages per second going from the server to the client. The client is supposed to operate under "internet conditions". THis means possibly home end users behind standard NAT devices (i.e. typical DSL routers) - a firewalled secure and thus "open" network can not be assumed. I want to have as little latency and as little overhad for the communication as possible. What is the technologally best way to handle the message bus callback? I Have no problem regularly calling to the server for message delivery if something needs to be sent... ...but what are my options to handle the messagtes from the server to the client? WsDualHttp does work how? Especially under a NAT scenario? Just as a note: polling is most likely out - the main problem here is that I would have a significant overhead OR a significant delay, both aren ot really wanted. Technically I would love some sort of streaming appraoch, where the server can write messags to a stream while he generates them and they get sent to the client as they come. Not esure this is doable with WCF, though (if not, I may acutally decide to handle the whole message part outside of WCF and just do control / login / setup / destruction via WCF).

• Basic syntax for an animation loop?

  - by Moshe

  I know that jQuery, for example, can do animation of sorts. I also know that at the very core of the animation, there must me some sort of loop doing the animation. What is an example of such a loop? A complete answer should ideally answer the following questions: What is a basic syntax for an effective animation recursion that can animate a single property of a particular object at a time? The function should be able to vary its target object and property of the object. What arguments/parameters should it take? What is a good range of reiterating the loop? In milliseconds? (Should this be a parameter/argument to the function?) REMEMBER: The answer is NOT necessarily language specific, but if you are writing in a specific language, please specify which one. Error handling is a plus. {Nothing is more irritating (for our purposes) than an animation that does something strange, like stopping halfway through.} Thanks!

• Can I use the auto-generated Linq-to-SQL entity classes in 'disconnected' mode?

  - by Gary McGill

  Suppose I have an automatically-generated Employee class based on the Employees table in my database. Now suppose that I want to pass employee data to a ShowAges method that will print out name & age for a list of employees. I'll retrieve the data for a given set of employees via a linq query, which will return me a set of Employee instances. I can then pass the Employee instances to the ShowAges method, which can access the Name & Age fields to get the data it needs. However, because my Employees table has relationships with various other tables in my database, my Employee class also has a Department field, a Manager field, etc. that provide access to related records in those other tables. If the ShowAges method were to invoke any of those methods, this would cause lots more data to be fetched from the database, on-demand. I want to be sure that the ShowAges method only uses the data I have already fetched for it, but I really don't want to have to go to the trouble of defining a new class which replicates the Employee class but has fewer methods. (In my real-world scenario, the class would have to be considerably more complex than the Employee class described here; it would have several 'joined' classes that do need to be populated, and others that don't). Is there a way to 'switch off' or 'disconnect' the Employees instances so that an attempt to access any property or related object that's not already populated will raise an exception? If not, then I assume that since this must be a common requirement, there might be an already-established pattern for doing this sort of thing?

• How do attribute classes work?

  - by AaronLS

  My searches keep turning up only guides explaining how to use and apply attributes to a class. I want to learn how to create my own attribute classes and the mechanics of how they work. How are attribute classes instantiated? Are they instantiated when the class they are applied to is instantiated? Is one instantiated for each class instantiated that it is applied to? E.g. if I apply the SerializableAttribute class to a MyData class, and I instantiate 5 MyData instances, will there be 5 instances of the SerializbleAttribute class created behind the scenes? Or is there just one instance shared between all of them? How do attribute class instances access the class they are associated with? How does a SerializableAttribute class access the class it is applied to so that it can serialize it's data? Does it have some sort of SerializableAttribute.ThisIsTheInstanceIAmAppliedTo property? :) Or does it work in the reverse direction that whenever I serialize something, the Serialize function I pass the MyClass instance to will reflectively go through the Attributes and find the SerialiableAttribute instance?

• Finding the last focused element

  - by Joshua Cody

  I'm looking to determine which element had the last focus in a series of inputs, that are added dynamically by the user. This code can only get the inputs that are available on page load: $('input.item').focus(function(){ $(this).siblings('ul').slideDown(); }); And this code sees all elements that have ever had focus: $('input.item').live('focus', function(){ $(this).siblings('ul').slideDown(); }); The HTML structure is this: <ul> <li><input class="item" name="goals[]"> <ul> <li>long list here</li> <li>long list here</li> <li>long list here</li> </ul></li> </ul> <a href="#" id="add">Add another</a> On page load, a single input loads. Then with each add another, a new copy of the top unordered list's contents are made and appended, and the new input gets focus. When each gets focus, I'd like to show the list beneath it. But I don't seem to be able to "watch for the most recently focused element, which exists now or in the future." To clarify: I'm not looking for the last occurrence of an element in the DOM tree. I'm looking to find the element that currently has focus, even if said element is not present upon original page load. So in the above image, if I were to focus on the second element, the list of words should appear under the second element. My focus is currently on the last element, so the words are displayed there. Do I have some sort of fundamental assumption wrong?

• Reverse ordered list for jquery submitted comments

  Hey guys I have one more question lol. I am using a script that allows users to submit comments through jquery ajax, however when they are submitted, the submitted comments submit at the bottom of the other comments which are sorted in descending order (newest on top) when the page first loads (due to mysql query). Is there a way to make it submit on top through some sort of sorting javascript function? function prepare(response) { var d = new Date(); count++; d.setTime(response.time*1000); var mytime = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); var string = '<li class="shoutbox-list" id="list-'+count+'">' + '<span class="date">'+mytime+'</span>' + '<span class="shoutbox-list-nick"><a href="statistics.php?user='+response.user+'">'+response.user+'</a>:</span>' + '<span class="msg">'+response.message+'</span>' +'</li>'; return string; } function success(response, status) { if(status == 'success') { lastTime = response.time; $('#daddy-shoutbox-list').append(prepare(response)); $('input[name=message]').attr('value', '').focus(); $('#list-'+count).fadeIn('slow'); timeoutID = setTimeout(refresh, 3000); } } <div id="daddy-shoutbox"> <ol id="daddy-shoutbox-list"></ol> </div>

  Create a DTD to record the sellers of merchandise to the Second-hand shop. Each seller has the child elements sellerID (in the format KSXXXXXXX), name, address, phone and sighted_identification. ? the name element has child elements of title and firstname and surname ? the address element has child elements address_line, suburb, state and postcode ? the sighted_identification can be any of the following – passport – drivers licence – birth certificate – Medicare card. –1.

Create an XML document for five sellers including at least two with multiple sighted identifications. 3. Create an XSLT style sheet to logically display all of the seller’s details. Note 1: it may help you to create lists for both sellers and for sighted_identification. Note 2: The shops database stores the sighted identification of sellers as p, dl, bc and mc rather than by their full name, so creating an entity for each type is required. Note 3: Your XSLT should order the sellers by sellerID – for this reason don’t have them ordered correctly in the XML file – rather sort the sellerID within the XSLT. OUTPUT SHOULD BE SOMETHING LIKE THIS SELLER ID : NAME: ADDRESS : PHONE : IDENTIFICATION : IDENTIFICATION : IDENTIFICATION :
