  • PHP/XPath: Iterating through ancestor nodes in XML using SimpleXML

    - by StackOverflowNewbie
    I need to loop through the Ancestors nodes in order to get corresponding BrowseNodeId and Name values. How do I do this using XPath? I'm trying something like the the following, but it's not working: //BrowseNode[1]//Ancestors[1]/BrowseNode/BrowseNodeId/text() //BrowseNode[1]//Ancestors[1]/BrowseNode/Name/text() I think the //Ancestors part of the XPath is actually searching the entire XML tree. What I need to do is visit each node to get the needed values. How do I do this? In the example below, I want: Europe - History - Subjects - Books. Example XML: <BrowseNode> <BrowseNodeId>4952</BrowseNodeId> <Name>France</Name> <Ancestors> <BrowseNode> <BrowseNodeId>4935</BrowseNodeId> <Name>Europe</Name> <Ancestors> <BrowseNode> <BrowseNodeId>9</BrowseNodeId> <Name>History</Name> <Ancestors> <BrowseNode> <BrowseNodeId>1000</BrowseNodeId> <Name>Subjects</Name> <IsCategoryRoot>1</IsCategoryRoot> <Ancestors> <BrowseNode> <BrowseNodeId>283155</BrowseNodeId> <Name>Books</Name> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode>

  • Measuring time spent in application / thread

    - by Adamski
    I am writing a simulation in Java whereby objects act under Newtonian physics. An object may have a force applied to it and the resulting velocity causes it to move across the screen. The nature of the simulation means that objects move in discrete steps depending on the time ellapsed between the current and previous iteration of the animation loop; e.g public void animationLoop() { long prev = System.currentTimeMillis(); long now; while(true) { long now = System.currentTimeMillis(); long deltaMillis = now - prev; prev = now; if (deltaMillis > 0) { // Some time has passed for (Mass m : masses) { m.updatePosition(deltaMillis); } // Do all repaints. } } } A problem arises if the animation thread is delayed in some way causing a large amount of time to ellapse (the classic case being under Windows whereby clicking and holding on minimise / maximise prevents a repaint), which causes objects to move at an alarming rate. My question: Is there a way to determine the time spent in the animation thread rather than the wallclock time, or can anyone suggest a workaround to avoid this problem? My only thought so far is to contstrain deltaMillis by some upper bound.

  • How do I create a class repository in Java and do I really need it?

    - by Roman
    I have a large number of objects which are identified by names (strings). So, I would like to have a kind of mapping from object name to the class instances. I was told that in this situation I can use a "repository" class which works like that: Server myServer = ServerRepository.getServer("NameOfServer"); So, if there is already an object (sever) with the "NameOfServer" it will be returned by the "getServer". If such an object does not exist yet, it will be created and returned by the "getServer". So, my question is how to program such a "repository" class? In this class I have to be able to check if there is an instance of a given class such that it has a given value of a given field. How can I do it? I need to have a kind of loop over all existing object of a given class? Another part of my question is why I cannot use associative arrays (associative container, map, mapping, dictionary, finite map)? (I am not sure how do you call it in Java) In more details, I have an "array" which maps names of objects to objects. So, whenever I create a new object, I add a new element to the array: myArray["NameOfServer"] = new Server("NameOfServer").

  • Will this class cause memory leaks, and does anything need disposing of? (asp.net vb)

  • How to count the Chinese word in a file using regex in perl?

    - by Ivan
    I tried following perl code to count the Chinese word of a file, it seems working but not get the right thing. Any help is greatly appreciated. The Error message is Use of uninitialized value $valid in concatenation (.) or string at word_counting.pl line 21, <FILE> line 21. Total things = 125, valid words = which seems to me the problem is the file format. The "total thing" is 125 that is the string number (125 lines). The strangest part is my console displayed all the individual Chinese words correctly without any problem. The utf-8 pragma is installed. #!/usr/bin/perl -w use strict; use utf8; use Encode qw(encode); use Encode::HanExtra; my $input_file = "sample_file.txt"; my ($total, $valid); my %count; open (FILE, "< $input_file") or die "Can't open $input_file: $!"; while (<FILE>) { foreach (split) { #break $_ into words, assign each to $_ in turn $total++; next if /\W|^\d+/; #strange words skip the remainder of the loop $valid++; $count{$_}++; # count each separate word stored in a hash ## next comes here ## } } print "Total things = $total, valid words = $valid\n"; foreach my $word (sort keys %count) { print "$word \t was seen \t $count{$word} \t times.\n"; } ##---Data---- sample_file.txt ??????,???????,????.??????.????:"?????????????,??????,????????.????????,?????????, ???????????.????????,???????????,??????,??????.???:`??,???????????.'?????, ??????????."??????,??????.????.???, ????????????,????,??????,?????????,??????????????. ????????,??????,???????????,????????,????????.????,????,???????, ??????????,??????,????????.??????.

  • Finding cause of memory leaks in large PHP stacks

    - by Mike B
    I have CLI script that runs over several thousand iterations between runs and it appears to have a memory leak. I'm using a tweaked version of Zend Framework with Smarty for view templating and each iteration uses several MB worth of code. The first run immediately uses nearly 8MB of memory (which is fine) but every following run adds about 80kb. My main loop looks like this (very simplified) $users = UsersModel::getUsers(); foreach($users as $user) { $obj = new doSomethingAwesome(); $obj->run($user); $obj = null; unset($obj); } The point is that everything in scope should be unset and the memory freed. My understanding is that PHP runs through its garbage collection process at it's own desire but it does so at the end of functions/methods/scripts. So something must be leaking memory inside doSomethingAwesome() but as I said it is a huge stack of code. Ideally, I would love to find some sort of tool that displayed all my variables no matter the scope at some point during execution. Some sort of symbol-table viewer for php. Does anything like that or any other tools that could help nail down memory leaks in php exist?

  • PHP/Javascript: Need help removing line break from code

    - by Josh K
    I am trying to get names from a .txt file. I am using file('filename.txt') but if i use a php for loop to try and trim the names, it comes out on multiple lines: This is the actual line that prints the javascript (NOTE: I am going to be putting these names into a select box, if you can fix the problem at hand the rest of the code should work so unless you a big problem with it you don't need to comment) <?php for($i=1; $i < 27; $i++){ echo "selbox.options[selbox.options.length] = new Option('".lines[$i]."','".$lines[$i]."');\n"; } ?> Heres how it comes out on the browser: selbox.options[selbox.options.length] = new Option('Djamal ABDOUN ','First1 Last1 '); selbox.options[selbox.options.length] = new Option('Chadli AMRI ','First2 Last2 '); I need those to be on one line so i dont get a unterminated string literal js error Any ideas on what i can do here? EDIT: Oh i should probably mention, the $lines var is initiated like this: $lines = file('filename.txt'); and inside that file i have formatted like this First1 Last1 First2 Last2 First3 Last3 etc. and i hit delete after each Last name until the next first name is touching, then hit enter to put it on a new line (Editor is notepad++)

  • How to prevent ADO.NET from altering double values when it reads from Excel files

    - by Khnle
    I have the following rows in my Excel input file: Column1 Column2 0-5 3.040 6 2.957 7 2.876 and the following code which uses ADO.NET to read it: string fileName = "input.xls"; var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName); var dbConnection = new OleDbConnection(connectionString); dbConnection.Open(); try { var dbCommand = new OleDbCommand("SELECT * FROM [Sheet1$]", dbConnection); var dbReader = dbCommand.ExecuteReader (); while (dbReader.Read()) { string col1 = dbReader.GetValue(0).ToString(); string col2 = dbReader.GetValue(1).ToString(); } } finally { dbConnection.Close(); } The results are very disturbing. Here's why: The values of each column in the first time through the loop: col1 is empty (blank) col2 is 3.04016411633586 Second time: col1 is 6 col2 is 2.95722928448829 Third time: col1 is 7 col2 is 2.8763272933077 The first problem happens with col1 in the first iteration. I expect 0-5. The second problem happens at every iteration with col2 where ADO.NET obviously alters the values as it reads them. How to stop this mal-behavior?

  • Looping through my table, how do I know if the checkbox is checked?

    - by radbyx
    How I build my table: for (var i = 0; i < result.length; i++) { var item = result[i]; // Firma, BygningselementNavn, BrugerNavn, EmailAdresse, Telefon tbody = tbody + '<tr class="modtagerRow"><td>' + item.FirmaNavn + '</td>' + '<td>' + item.BygningselementNavn + '</td>' + '<td>' + item.BrugerNavn + '</td>' + '<td>' + item.EmailAdresse + '</td>' + '<td>' + item.Telefon + '</td>' // Medtag tbody = tbody + '<td style="text-align:center"><input type="checkbox" value="' + item.BygningselementId + '_' + item.BrugerId + '" name="BygningsElementBrugerComboIds"></td>' + '</tr>'; } $('#ModtagereTable tbody').append(tbody) How I am trying to loop through the rows and adding a CSS class to rows that has it's checkbox checked. 1) I get the indexies to the console, but I can't make the if condition for all the checked checkboxes. 2) Also I am not sure if I can you $( this ) or I should use something else, when adding the class .hideForSendMailConfirm? // Looping rows in table $( ".modtagerRow" ).each(function(index, element) { console.log('index: ' + index); // if if (element.checked) { $( this ).addClass(".hideForSendMailConfirm"); } });

  • Learning Java, how to type text on canvas?

    - by Voley
    I'm reading a book by Eric Roberts - Art and science of java and it got an excersise that I can't figure out - You have to make calendar, with GRect's, 7 by 6, that goes ok, the code part is easy, but also you have to type the numbers of the date on those rectangles, and it's kinda hard for me, there is nothing about it in the book. I tried using GLabel thing, but here arises the problem that I need to work on those numbers, and it says "can't convert from int to string and vice versa". GLabel (string, posX, posY) - it is not accepting int as a parameter, only string, I even tried typecasting, still not working. For example I want to make a loop int currentDate = 1; while (currentDate < 31) { add(new Glabel(currentDate, 100, 100); currentDate++; This code is saying that no man, can't convert int to string. If i try changing currentDate to string, it works, but I got a problem with calculation, as I can't manipulate with number in string, it doesn't even allow to typecast it into int. How can I fix it? Maybe there is another class or method to type the text over those rectangles? I know about println but it doen't have any x or y coordinates, so I can't work with it. And I think it's only for console programs.

  • What is the complexity of this specialized sort

    - by ADB
    I would like to know the complexity (as in O(...) ) of the following sorting algorithm: there are B barrels that contains a total of N elements, spread unevenly across the barrels. the elements in each barrel are already sorted The sort takes combines all the elements from each barrel in a single sorted list: using an array of size B to store the last sorted element of each barrel (starting at 0) check each barrel (at the last stored index) and find the smallest element copy the element in the final sorted array, increment array counter increment the last sorted element for the barrel we picked from perform those steps N times or in pseudo: for i from 0 to N smallest = MAX_ELEMENT foreach b in B if bIndex[b] < b.length && b[bIndex[b]] < smallest smallest_barrel = b smallest = b[bIndex[b]] result[i] = smallest bIndex[smallest_barrel] += 1 I thought that the complexity would be O(n), but the problem I have with finding the complexity is that if B grows, it has a larger impact than if N grows because it adds another round in the B loop. But maybe that has no effect on the complexity?

  • AddEvenLister fires off immediately after being attached

    - by Diego
    I want to know how to correctly add an Event Listener like onClick to a dynamic div. Here’s my snippet: var $menu = new Array(2); createDiv('yes'); function createDiv(title) { var $class = 'menuLink'; var $title = 'title'; for(var i=0; i<$menu.length;i++) { $title = 'title'; var newdiv = document.createElement('div'); newdiv.setAttribute('class', $class); newdiv.setAttribute('id', 'item'+i); newdiv.addEventListener('onclick', clickHandle(newdiv.id),false); if (title) { newdiv.innerHTML = $title; } else { newdiv.innerHTML = "No Title"; } document.getElementById('menu').appendChild(newdiv); showMenu(); } } function clickHandle(e) { if(e == 'item0') { alert('Link is' + ' ' + e); }else{ alert('Another Link'); } } Here's my problem, the snippet works fine, It creates my divs, adds id's values and all, but the event fires off as soon as the event is attached, so while the for loop is creating the divs the alert window says: Link is item0, and immediately after this it says: Another Link. Am I misunderstanding this? (I used this method zillions of times in AS3 with the expected result, just attached a function waiting for a click). What I want is that my Divs wait for the user to click on them, not to fire off immediately after of being attached. Thanks for any hint on this one. Greetings. Ps. IE doesn't support addEventListener, but I want to resolve this before cross to the IE sea of madness, but I will appreciate the IE approach as well. - I tried "onclick" and just 'click' into the addEventListener line, both with the same result described above.

  • Is there a more elegant way to act on the first and last items in a foreach enumeration than count++

    - by Edward Tanguay
    Is there a more elegant way to act on the first and last items when iterating through a foreach loop than incrementing a separate counter and checking it each time? For instance, the following code outputs: >>> [line1], [line2], [line3], [line4] <<< which requires knowing when you are acting on the first and last item. Is there a more elegant way to do this now in C# 3 / C# 4? It seems like I could use .Last() or .First() or something like that. using System; using System.Collections.Generic; using System.Text; namespace TestForNext29343 { class Program { static void Main(string[] args) { StringBuilder sb = new StringBuilder(); List<string> lines = new List<string> { "line1", "line2", "line3", "line4" }; int index = 0; foreach (var line in lines) { if (index == 0) sb.Append(">>> "); sb.Append("[" + line + "]"); if (index < lines.Count - 1) sb.Append(", "); else sb.Append(" <<<"); index++; } Console.WriteLine(sb.ToString()); Console.ReadLine(); } } }

  • Optimizing a bin-placement algorithm

    - by user258651
    Alright, I've got two collections, and I need to place elements from collection1 into the bins (elements) of collection2, based on whether their value falls within a given bin's range. For a concrete example, assume I have a sorted collection objects (bins) which have an int range ([1...4], [5..10], etc). I need to determine the range an int falls in, and place it in the appropriate bin. foreach(element n in collection1) { foreach(bin m in collection2) { if (m.inRange(n)) { m.add(n); break; } } } So the obvious NxM complexity algorithm is there, but I really would like to see Nxlog(M). To do this I'd like to use BinarySearch in place of the inner foreach loop. To use BinarySearch, I need to implement an IComparer class to do the searching for me. The problem I'm running into is this approach would require me to make an IComparer.Compare function that compares two different types of objects (an element to its bin), and that doesn't seem possible or correct. So I'm asking, how should I write this algorithm?

  • VB.NET Syntax Coding

    - by Yiu Korochko
    I know many people ask how some of these are done, but I do not understand the context in which to use the answers, so... I'm building a code editor for a subversion of Python language, and I found a very decent way of highlighting keywords in the RichTextBox through this: bluwords.Add(KEYWORDS GO HERE) If scriptt.Text.Length > 0 Then Dim selectStart2 As Integer = scriptt.SelectionStart scriptt.Select(0, scriptt.Text.Length) scriptt.SelectionColor = Color.Black scriptt.DeselectAll() For Each oneWord As String In bluwords Dim pos As Integer = 0 Do While scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) >= 0 pos = scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) scriptt.Select(pos, oneWord.Length) scriptt.SelectionColor = Color.Blue pos += 1 Loop Next scriptt.SelectionStart = selectStart2 End If (scriptt is the richtextbox) But when any decent amount of code is typed (or loaded via OpenFileDialog) chunks of the code go missing, the syntax selection falls apart, and it just plain ruins it. I'm looking for a more efficient way of doing this, maybe something more like visual studio itself...because there is NO NEED to highlight all text, set it black, then redo all of the syntaxing, and the text begins to over-right if you go back to insert characters between text. Also, in this version of Python, hash (#) is used for comments on comment only lines and double hash (##) is used for comments on the same line. Now I saw that someone had asked about this exact thing, and the working answer to select to the end of the line was something like: ^\'[^\r\n]+$|''[^\r\n]+$ which I cannot seem to get into practice. I also wanted to select text between quotes and turn it turquoise, such as between the first quotation mark and the second, the text is turquoise, and the same between the 3rd and 4th etcetera... Any help is appreciated!

I have an array of players as follows: var player; var players = new Array(); //loop for number of players player = new Object(); player.id = theID; players[i] = player; Then my AJAX call looks like this: JSONplayers = JSON.stringify(players); $.ajax({ type: "POST", url: "php/ajax_send_players.php", data: { "players" : JSONplayers } On the PHP side the decode function looks like this $players = $_REQUEST['players']; echo var_dump($players); $players = json_decode($players); echo 'players: ' .$players. '--'. $players[0] . '--'. $players[0]->id; Debugging in chrome, the JSON players var looks like this before it is sent: JSONplayers: "[{"id":"Percipient"},{"id":"4"}]" And when I vardump in PHP it looks OK, giving this: string(40) "[{\"id\":\"Percipient\"},{\"id\":\"4\"}]" But I can't access the PHP array, and the echo statement about starting with players: outputs this: players: ---- Nothing across the board...maybe it has something to do with the \'s in the array, I am new to this and might be missing something very simple. Any help would be greatly appreciated. note I've also tried json_decode($players, true) to get it as an assoc array but get similar results.

  • Options for displaying OG groups a node is published for on node page?

    - by Erik Töyrä
    What I want I have several OG groups in which content can be published. I would like to display which OG groups a node has been published for when viewing the node page. Like in "This page is published for: Department A, Department B." The code snipped below shows the data I have in the $node object in node.tpl.php. This data is generated by the OG module. Extracted data from $node ... [og_groups] => Array ( [993] => 993 [2078] => 2078 ) [og_groups_both] => Array ( [993] => Department A [2078] => Department B ) ... I know I could loop through the og_groups_both array in node.tpl.php and generate the output from there, but it feels like a quite dirty solution. The ideal solution would be to have a $og_groups variable in node.tpl.php, similiar to how $submitted is used in node.tpl.php (see below). Example of how $submitted is used <?php if ($submitted): ?> <div class="submitted"><?php print $submitted; ?></div> <?php endif; ?> Should I use hook_load() in a custom module to insert the new variable $og_groups in $node? What options do I have and which solution would you recommend?

  • Strange behaviour of NSScanner on simple whitespace removal

    - by Michael Waterfall
    I'm trying to replace all multiple whitespace in some text with a single space. This should be a very simple task, however for some reason it's returning a different result than expected. I've read the docs on the NSScanner and it seems like it's not working properly! NSScanner *scanner = [[NSScanner alloc] initWithString:@"This is a test of NSScanner !"]; NSMutableString *result = [[NSMutableString alloc] init]; NSString *temp; NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet]; while (![scanner isAtEnd]) { // Scan upto and stop before any whitespace [scanner scanUpToCharactersFromSet:whitespace intoString:&temp]; // Add all non whotespace characters to string [result appendString:temp]; // Scan past all whitespace and replace with a single space if ([scanner scanCharactersFromSet:whitespace intoString:NULL]) { [result appendString:@" "]; } } But for some reason the result is @"ThisisatestofNSScanner!" instead of @"This is a test of NSScanner !". If you read through the comments and what each line should achieve it seems simple enough!? scanUpToCharactersFromSet should stop the scanner just as it encounters whitespace. scanCharactersFromSet should then progress the scanner past the whitespace up to the non-whitespace characters. And then the loop continues to the end. What am I missing or not understanding?

  • How to encapsulate a WinAPI application into a C++ class

    - by Semen Semenych
    There is a simple WinAPI application. All it does currently is this: register a window class register a tray icon with a menu create a value in the registry in order to autostart and finally, it checks if it's unique using a mutex As I'm used to writing code mainly in C++, and no MFC is allowed, I'm forced to encapsulate this into C++ classes somehow. So far I've come up with such a design: there is a class that represents the application it keeps all the wndclass, hinstance, etc variables, where the hinstance is passed as a constructor parameter as well as the icmdshow and others (see WinMain prototype) it has functions for registering the window class, tray icon, reigstry information it encapsulates the message loop in a function In WinMain, the following is done: Application app(hInstance, szCmdLIne, iCmdShow); return app.exec(); and the constructor does the following: registerClass(); registerTray(); registerAutostart(); So far so good. Now the question is : how do I create the window procedure (must be static, as it's a c-style pointer to a function) AND keep track of what the application object is, that is, keep a pointer to an Application around. The main question is : is this how it's usually done? Am I complicating things too much? Is it fine to pass hInstance as a parameter to the Application constructor? And where's the WndProc? Maybe WndProc should be outside of class and the Application pointer be global? Then WndProc invokes Application methods in response to various events.
