  • tabs on web page and seo

    - by GaVrA
    I know there is a lot of js plugins to do "tabs", but also i can do it my self. Just have some elements with display:none and when you click some other element display changes to block, or something like that. Now, i have a one site i am developing, where i am giving specific users(all within one usergroup) access to edit only one page which i have created. That part is done. Now i have a request to give those users ability to edit 2 more sub pages, but since its all gonna be the same, like text with some pictures, i was thinking to put 3 textarea's so they will have 1 page where they can edit content of all those 3 pages. What i also thought was to only have one page and on it to have 3 tabs. Each tab for each possible page. When i started thinking about that the only concern was seo. How does seo works regarding elements with display:none? What jquery tabs plugin do you recommend that has the ability to access tabs via id of the element in url? I was looking at jquery ui demo but there when you get the url of one of those tabs and try to open it in new window, that tab is not opened. For example this link: http://jqueryui.com/demos/tabs/#tabs-2 It does not open tab #2... Any help is appreciated!

  • SQL group results as a column array

    - by Radek
    Hi guys, this is an SQL question and don't know which type of JOIN, GROUP BY etc. to use, it is for a chat program where messages are related to rooms and each day in a room is linked to a transcript etc. Basically, when outputting my transcripts, I need to show which users have chatted on that transcript. At the moment I link them through the messages like so: SELECT rooms.id, rooms.name, niceDate, room_transcripts.date, long FROM room_transcripts JOIN rooms ON room_transcripts.room=rooms.id JOIN transcript_users ON transcript_users.room=rooms.id AND transcript_users.date=room_transcripts.date JOIN users ON transcript_users.user=users.id WHERE room_transcripts.deleted=0 AND rooms.id IN (1,2) ORDER BY room_transcripts.id DESC, long ASC The result set looks like this: Array ( [0] => Array ( [id] => 2 [name] => Room 2 [niceDate] => Wednesday, April 14 [date] => 2010-04-14 [long] => Jerry Seinfeld ) [1] => Array ( [id] => 1 [name] => Room 1 [niceDate] => Wednesday, April 14 [date] => 2010-04-14 [long] => Jerry Seinfeld ) [2] => Array ( [id] => 1 [name] => Room 1 [niceDate] => Wednesday, April 14 [date] => 2010-04-14 [long] => Test Users ) ) I would like though for each element in the array to represent one transcript entry and for the users to be grouped in an array as the entry's element. So 'long' will be an array listing all the names. Can this be done? At the moment I just append the names and when the transcript date and room changes I echo them retrospectively, but I will do the same for files and highlighted messages and it's messy. Thanks.

  • Virtual properties duplicated during serialization when XmlElement attribute used

    - by Laramie
    The Goal: XML serialize an object that contains a list of objects of that and its derived types. The resulting XML should not use the xsi:type attribute to describe the type, to wit the names of the serialized XML elements would be an assigned name specific to the derived type, not always that of the base class, which is the default behavior. The Attempt: After exploring IXmlSerializable and IXmlSerializable with eerie XmlSchemaProvider methods and voodoo reflection to return specialized schemas and an XmlQualifiedName over the course of days, I found I was able to use the simple [XmlElement] attribute to accomplish the goal... almost. The Problem: Overridden properties appear twice when serializing. The exception reads "The XML element 'overriddenProperty' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element." I attempted using a *Specified property (see code), but it didn't work. Sample Code: Class Declaration using System; using System.Collections.Generic; using System.Xml.Serialization; [XmlInclude(typeof(DerivedClass))] public class BaseClass { public BaseClass() { } [XmlAttribute("virt")] public virtual string Virtual { get; set; } [XmlIgnore] public bool VirtualSpecified { get { return (this is BaseClass); } set { } } [XmlElement(ElementName = "B", Type = typeof(BaseClass), IsNullable = false)] [XmlElement(ElementName = "D", Type = typeof(DerivedClass), IsNullable = false)] public List<BaseClass> Children { get; set; } } public class DerivedClass : BaseClass { public DerivedClass() { } [XmlAttribute("virt")] public override string Virtual { get { return "always return spackle"; } set { } } } Driver: BaseClass baseClass = new BaseClass() { Children = new List<BaseClass>() }; BaseClass baseClass2 = new BaseClass(){}; DerivedClass derivedClass1 = new DerivedClass() { Children = new List<BaseClass>() }; DerivedClass derivedClass2 = new DerivedClass() { Children = new List<BaseClass>() }; baseClass.Children.Add(derivedClass1); baseClass.Children.Add(derivedClass2); derivedClass1.Children.Add(baseClass2); I've been wrestling with this on and off for weeks and can't find the answer anywhere.

  • Switch statement usage - C

    - by Jamie Keeling
    Hello, I have a thread function on Process B that contains a switch to perform certain operations based on the results of an event sent from Process A, these are stored as two elements in an array. I set the first element to the event which signals when Process A has data to send and I have the second element set to the event which indicates when Process A has closed. I have began to implement the functionality for the switch statement but I'm not getting the results as I expect. Consider the following: // //Thread function DWORD WINAPI ThreadFunc(LPVOID passedHandle) { for(i = 0; i < 2; i++) { ghEvents[i] = OpenEvent(EVENT_ALL_ACCESS, FALSE, TEXT("Global\\ProducerEvents")); if(ghEvents[i] == NULL) { getlasterror = GetLastError(); } } dwProducerEventResult = WaitForMultipleObjects( 2, ghEvents, FALSE, INFINITE); switch (dwProducerEventResult) { case WAIT_OBJECT_0 + 0: { //Producer sent data //unpackedHandle = *((HWND*)passedHandle); MessageBox(NULL,L"Test",L"Test",MB_OK); break; } case WAIT_OBJECT_0 + 1: { //Producer closed ExitProcess(1); break; } default: return; } } As you can see if the event in the first array is signalled Process B should display a simple message box, if the second array is signalled the application should close. When I actually close Process A, Process B displays the message box instead. If I leave the first case blank (Do nothing) both applications close as they should. Furthermore Process B sends data an error is thrown (When I comment out the unpacking): Have I implemented my switch statement incorrectly? I though I handled the unpacking of the HWND correctly too, any suggestions? Thanks for your time.

  • TranslateTransform for drag and drop in Silverlight

    - by fuzzyman
    We're trying to implement drag and drop in Silverlight (3). We want users to be able to drag elements from a treeview onto another part of a UI. The parent element is a Grid, and we've been trying to use a TranslateTransform along with the MouseLeftButtonDown, MouseMove (etc) events, as recommended by various online examples. For example: http://www.85turns.com/2008/08/13/drag-and-drop-silverlight-example/ We're doing this in IronPython, but that should be more or less irrelevant. The drag start is correctly initiated, but the item we are dragging appears in the 'wrong' location (offset a few hundred pixels to the right and down from the cursor) and I can't for the life of me work out why. Basic xaml: <Grid x:Name="layout_root"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition Height="120"/> </Grid.RowDefinitions> <Border x:Name="drag" Background="LightGray" Width="40" Height="15" Visibility="Collapsed" Canvas.ZIndex="10"> <Border.RenderTransform> <TranslateTransform x:Name="transform" X="0" Y="0" /> </Border.RenderTransform> <TextBlock x:Name="dragText" TextAlignment="Center" Foreground="Gray" Text="foo" /> </Border> ... </Grid> The startDrag method is triggered by the MouseLeftButtonDown event (on a TextBlock in a TreeViewItem.Header). onDrag is triggered by MouseMove. In the following code self.root is Application.Current.RootVisual (top level UI element from app.xaml): def startDrag(self, sender, event): self.root.drag.Visibility = Visibility.Visible self.root.dragText.Text = sender.Text position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y self.root.CaptureMouse() self._captured = True def onDrag(self, sender, event): if self._captured: position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y The dragged item follows the mouse move, but is offset considerably. Any idea what I am doing wrong and how to correct it?

  • restrict documents for mapreduce with mongoid

    - by theBernd
    I implemented the pearson product correlation via map / reduce / finalize. The missing part is to restrict the documents (representing users) to be processed via a filter query. For a simple query like mapreduce(mapper, reducer, :finalize => finalizer, :query => { :name => 'Bernd' }) I get this to work. But my filter criteria is a little bit more complicated: I have one set of preferences which need to have at least one common element and another set of preferences which may not have a common element. In a later step I also want to restrict this to documents (users) within a certain geographical distance. Currently I have this code working in my map function, but I would prefer to separate this into either query params as supported by mongoid or a javascript function. All my attempts to solve this failed since the code is either ignored or raises an error. I did a couple of tests. A regular find like User.where(:name.in => ['Arno', 'Bernd', 'Claudia']) works and returns #<Mongoid::Criteria:0x00000101f0ea40 @selector={:name=>{"$in"=>["Arno", "Bernd", "Claudia"]}}, @options={}, @klass=User, @documents=[]> Trying the same with mapreduce User.collection. mapreduce(mapper, reducer, :finalize => finalizer, :query => { :name.in => ['Arno', 'Bernd', 'Claudia'] }) fails with `serialize': keys must be strings or symbols (TypeError) in bson-1.1.5 The intermediate query parameter looks like this :query=>{#<Mongoid::Criterion::Complex:0x00000101a209e8 @key=:name, @operator="in">=>["Arno", "Bernd", "Claudia"]} and at least @operator looks a bit weird to me. I'm also uncertain if the class name can be omitted. BTW - I'm using mongodb 1.6.5-x86_64, and the mongoid 2.0.0.beta.20, mongo 1.1.5 and bson 1.1.5 gems on MacOS. What am I doing wrong? Thanks in advance.

  • Get notified when objective-c dom updates are ready initiated from webview

    - by Josh
    I am programmatically updating the DOM on a WebKit webview via DOMElement objects - for complex UI, there is usually a javascript component to any element that I add. This begs the need to be notified when the updates complete -- is there any such event? I know regular divs dont fire an onload or onready event, correct? The other assumption I had, which may be totally wrong, is that DOMElement updates aren't synchronous, so I can't do something like this and be confident it will meet with the label actually in the DOM: DOMElement *displayNameLabel = [document createElement:@"div"]; [displayNameLabel setAttribute:@"class" value:@"user-display-name"]; [displayNameLabel setTextContent:currentAvatar.avatarData.displayName]; [[document getElementById:@"user-card-content"] appendChild:displayNameLabel]; id win = [webView windowScriptObject]; [win evaluateWebScript:@"javascriptInstantiateLabel()"]; Is this true? I am using jquery within the body of the html already, so I don't mind subscribing to a particular classes set of events via "live." I thought I might be able to do something like: $(".some-class-to-be-added-later").live( "ready", function(){ // Instantiate some fantastic javascript here for .some-class }); but have experienced no joy so far. Is there any way on either side (objective-c since I don't programmatically firing javascript post load, or javascript) to be notified when the element is in the DOM? Thanks, Josh

  • 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"); } });

  • Open XML document ContentControls problem with signed id's

    - by willvv
    I have an application that generates Open XML documents with Content Controls. To create a new Content Control I use Interop and the method ContentControls.Add. This method returns an instance of the added Content Control. I have some logic that saves the id of the Content Control to reference it later, but in some computers I've been having a weird problem. When I access the ID property of the Content Control I just created, it returns a string with the numeric id, the problem is that when this value is too big, after I save the document, if I look through the document.xml in the generated document, the <w:id/> element of the <w:sdtPr/> element has a negative value, that is the signed equivalent of the value I got from the Id property of the generated control. For example: var contentControl = ContentControls.Add(...); var contentControlId = contentControl.ID; // the value of contentControlId is "3440157266" If I save the document and open it in the Package Explorer, the Id of the Content Control is "-854810030" instead of "3440157266". What have I figured out is this: ((int)uint.Parse("3440157266")).ToString() returns "-854810030" Any idea of why this happens? This issue is hard to replicate because I don't control the Id of the generated controls, the Id is automatically generated by the Interop libraries.

  • How to resize table via javascript in IE?

    - by MartyIX
    I've got this table: <table id="correctness" style="overflow: hidden;"> <tr><td style="overflow: hidden;"> <div id="correctness-message"></div> <span class="hide"> <button type="button" class="hide" onclick="new DisplayEffect('correctness').Hide(500);">Hide</button> </span> </td> </tr> </table> and a function for resizing the table: function resize(element, size) { element.style.height = size + "px";}; which is called for a certain amount of time (e.g. 1 second) with the ID of table (i.e. "correctness") in order to resize the table from zero height to its full height. This code works in Firefox and Chrome but it doesn't work in IE8. What it does is that it displays right away whole table even thought the height set in "resize" method is much lower. It seems that the cell sets the height of parent table and not the other way around. Is it possible to change the behaviour? I like changing the height of the table better because I can set visibility of the table easily. Thanks for any help!

  • Flex wordwrap issue with multiple text instances

    - by Craig Myles
    Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  • Absolutely positioned div on right causing scrollbar when the left doesn't

    - by Michael Snyder
    I'm trying to "flank" a centered div with some design elements that are absolutely positioned outside the main div's width. I'm getting a scroll bar due to the element on the right, but not the element on the left (IE6/7/8, Chrome, Firefox). How can I get rid of that horizontal scrollbar? <html> <head> <style type="text/css"> html, body { height: 100%; width: 100%; margin: 0; } body { text-align: center; } .wrapper { margin: 0 auto; position: relative; width: 960px; z-index: 0; } .main { background: #900; height: 700px; } .right, .left { position: absolute; height: 100px; width: 100px; } .right { background: #090; top: 0px; left: 960px; z-index: 1; } .left { background: #009; top: 0px; left: -100px; z-index: 1; } </style> </head> <body> <div class="wrapper"> <div class="main"></div> <div class="left"></div> <div class="right"></div> </div> </body> </html>

  • LINQ to XML contents of child records.

    - by Fossaw
    I have this LINQ to XML enquiry... var Records = from Item in XDoc.Root.Elements("Item") where (string)Item.Element("ItemNumber") == item.ID.ToString select Item; ... where ItemNumber is a reference number used in the XML, (originally written by this program but manually edited by "others"), and item.ID is the database version of the same thing. The query executes, and I can test for the number of entries in the result fine... if (Records.Count() < 1) ... you get the idea. I have established that there is only one record. Each Item has several child fields. I want to test the values of the child fields are reasonable before passing them on to the database update sub-system. The XML is produced by the program, but edited by users, so I need to really check what is coming back. So I tried... if (DB_English.ToString() != Records.Elements("English").ToString()) ... DB_English is from the database, but the XML in Records, does not contain the contents of that field, it contains... System.Xml.Linq.Extensions+<GetElements>d__29`1[System.Xml.Linq.XElement] ... so, how do I get the value of this element in the XML file? I need to check the field in the XML has not been altered, (the manual editors of this data file are not potentially 100% reliable).

  • Creating a custom Configuration

    - by Rob
    I created a customer configuration class Reports. I then created another class called "ReportsCollection". When I try and do the "ConfigurationManager.GetSection()", it doesn't populate my collection variable. Can anyone see any mistakes in my code? Here is the collection class: public class ReportsCollection : ConfigurationElementCollection { public ReportsCollection() { } protected override ConfigurationElement CreateNewElement() { throw new NotImplementedException(); } protected override ConfigurationElement CreateNewElement(string elementName) { return base.CreateNewElement(elementName); } protected override object GetElementKey(ConfigurationElement element) { throw new NotImplementedException(); } public Report this[int index] { get { return (Report)BaseGet(index); } } } Here is the reports class: public class Report : ConfigurationSection { [ConfigurationProperty("reportName", IsRequired = true)] public string ReportName { get { return (string)this["reportName"]; } //set { this["reportName"] = value; } } [ConfigurationProperty("storedProcedures", IsRequired = true)] public StoredProceduresCollection StoredProcedures { get { return (StoredProceduresCollection)this["storedProcedures"]; } } [ConfigurationProperty("parameters", IsRequired = false)] public ParametersCollection Parameters { get { return (ParametersCollection)this["parameters"]; } } [ConfigurationProperty("saveLocation", IsRequired = true)] public string SaveLocation { get { return (string)this["saveLocation"]; } } [ConfigurationProperty("recipients", IsRequired = true)] public RecipientsCollection Recipients { get { return (RecipientsCollection)this["recipients"]; } } } public class StoredProcedure : ConfigurationElement { [ConfigurationProperty("storedProcedureName", IsRequired = true)] public string StoredProcedureName { get { return (string)this["storedProcedureName"]; } } } public class StoredProceduresCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { throw new NotImplementedException(); } protected override ConfigurationElement CreateNewElement(string elementName) { return base.CreateNewElement(elementName); } protected override object GetElementKey(ConfigurationElement element) { throw new NotImplementedException(); } public StoredProcedure this[int index] { get { return (StoredProcedure)base.BaseGet(index); } } } } And here is the very straight-forward code to create the variable: ReportsCollection reportsCollection = (ReportsCollection) System.Configuration.ConfigurationManager.GetSection("ReportGroup");

  • Efficient method to calculate the rank vector of a list in Python

    - by Tamás
    I'm looking for an efficient way to calculate the rank vector of a list in Python, similar to R's rank function. In a simple list with no ties between the elements, element i of the rank vector of a list l should be x if and only if l[i] is the x-th element in the sorted list. This is simple so far, the following code snippet does the trick: def rank_simple(vector): return [rank for rank in sorted(range(n), key=vector.__getitem__)] Things get complicated, however, if the original list has ties (i.e. multiple elements with the same value). In that case, all the elements having the same value should have the same rank, which is the average of their ranks obtained using the naive method above. So, for instance, if I have [1, 2, 3, 3, 3, 4, 5], the naive ranking gives me [0, 1, 2, 3, 4, 5, 6], but what I would like to have is [0, 1, 3, 3, 3, 5, 6]. Which one would be the most efficient way to do this in Python? Footnote: I don't know if NumPy already has a method to achieve this or not; if it does, please let me know, but I would be interested in a pure Python solution anyway as I'm developing a tool which should work without NumPy as well.

  • How do I render *parts* of a svg file?

    - by Fake Code Monkey Rashid
    Hello good people! :) I want to render parts of a svg file by name but for the life of me I cannot figure out how to do so (using python + gtk). Here's the svg file in question: http://david.bellot.free.fr/svg-cards/files/SVG-cards-2.0.1.tar.gz On his site, David, says: You can draw a card either by rendering the file onto a pixmap and clipping each card manually or by using the card's name through a DOM interface. All cards are embedded into a SVG group. I don't know what he means by a DOM interface. I have done some searching and the best result I found that seems to fit what I want to do is: QSvgRenderer *renderer = new QSvgRenderer(QLatin1String("SvgCardDeck.svg")); QGraphicsSvgItem *black = new QGraphicsSvgItem(); QGraphicsSvgItem *red = new QGraphicsSvgItem(); black->setSharedRenderer(renderer); black->setElementId(QLatin1String("black_joker")); red->setSharedRenderer(renderer); red->setElementId(QLatin1String("red_joker")); Notice however that it is for Qt and is not even written in python. This is what I have so far: #!/usr/bin/env python from __future__ import absolute_import import cairo import gtk import rsvg from xml import xpath from xml.dom import minidom window = gtk.Window() window.set_title("Foo") window.set_size_request(256, 256) window.set_property("resizable", False) window.set_position(gtk.WIN_POS_CENTER) window.connect("destroy", gtk.main_quit) window.show() document = minidom.parse("cards.svg") element = xpath.Evaluate("//*[@id='1_club']", document)[0] xml = element.toxml() svg = rsvg.Handle() svg.write(xml) pixbuf = svg.get_pixbuf() image = gtk.Image() image.set_from_pixbuf(pixbuf) image.show() window.add(image) gtk.main() It doesn't work, of course. What am I missing?

  • C pointers and addresses

    - by yCalleecharan
    Hi, I always thought that *&p = p = &*p in C. I tried this code: #include <stdio.h> #include <stdlib.h> char a[] = "programming"; char *ap = &a[4]; int main(void) { printf("%x %x %x\n", ap, &*(ap), *&(ap)); /* line 13 */ printf("%x %x %x\n\n", ap+1, &*(ap+1), *&(ap+1)); /* line 14 */ } The first printf line (line 13) gives me the addresses: 40b0a8 40b0a8 40b0a8 which are the same as expected. But when I added the second printf line, Borland complains: "first.c": E2027 Must take address of a memory location in function main at line 14 I was expecting to get: 40b0a9 40b0a9 40b0a9. It seems that the expression *&(ap+1) on line 14 is the culprit here. I thought all three pointer expressions on line 14 are equivalent. Why am I thinking wrong? A second related question: The line char *ap = a; points to the first element of array a. I used char *ap = &a[4]; to point to the 5th element of array a. Is the expression char *ap = a; same as the expression char *ap = &a[0]; Is the last expression only more verbose than the previous one? Thanks a lot...

  • Why does XPath.selectNodes(context) always use the whole document in JDOM

    - by Simeon
    Hi, I'm trying to run the same query on several different contexts, but I always get the same result. This is an example xml: <root> <p> <r> <t>text</t> </r> </p> <t>text2</t> </root> So this is what I'm doing: final XPath xpath = XPath.newInstance("//t"); List<Element> result = xpath.selectNodes(thisIsThePelement); // and I've debuged it, it really is the <p> element And I always get both <t> elements in the result list. I need just the <t> inside the <p> I'm passing to the XPath object. Any ideas would be of great help, thanks.

  • How to access non-first matches with xpath in Selenium RC ?

    - by Gj
    I have 20 labels in my page: In [85]: sel.get_xpath_count("//label") Out[85]: u'20' And I can get the first one be default: In [86]: sel.get_text("xpath=//label") Out[86]: u'First label:' But, unlike the xpath docs I've found, I'm getting an error trying to subscript the xpath to get to the second label's text: In [87]: sel.get_text("xpath=//label[2]") ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multi-line statement', (216, 0)) ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multi-line statement', (1186, 0)) --------------------------------------------------------------------------- Exception Traceback (most recent call last) /Users/me/<ipython console> in <module>() /Users/me/selenium.pyc in get_text(self, locator) 1187 'locator' is an element locator 1188 """ -> 1189 return self.get_string("getText", [locator,]) 1190 1191 /Users/me/selenium.pyc in get_string(self, verb, args) 217 218 def get_string(self, verb, args): --> 219 result = self.do_command(verb, args) 220 return result[3:] 221 /Users/me/selenium.pyc in do_command(self, verb, args) 213 #print "Selenium Result: " + repr(data) + "\n\n" 214 if (not data.startswith('OK')): --> 215 raise Exception, data 216 return data 217 Exception: ERROR: Element xpath=//label[2] not found What gives?

  • Ocaml Pattern Matching

    - by Atticus
    Hey guys, I'm pretty new to OCaml and pattern matching, so I was having a hard time trying to figure this out. Say that I have a list of tuples. What I want to do is match a parameter with one of the tuples based on the first element in the tuple, and upon doing so, I want to return the second element of the tuple. So for example, I want to do something like this: let list = [ "a", 1; "b", 2"; "c", 3; "d", 4 ] ;; let map_left_to_right e rules = match e with | first -> second | first -> second | first -> second If I use map_left_to_right "b" list, I want to get 2 in return. I therefore want to list out all first elements in the list of rules and match the parameter with one of these elements, but I am not sure how to do so. I was thinking that I need to use either List.iter or List.for_all to do something like this. Any help would be appreciated. Thanks!

  • How do I select the shallowest matching elements with XPath?

    - by harpo
    Let's say I have this document. <a:Root> <a:A> <title><a:B/></title> <a:C> <item><a:D/></item> </a:C> </a:A> </a:Root> And I have an XmlNode set to the <a:A> element. If I say A.SelectNodes( "//a:*", namespaceManager ) I get B, C, and D. But I don't want D because it's nested in another "a:" element. If I say A.SelectNodes( "//a:*[not(ancestor::a:*)]", namespaceManager ) of course, I get nothing, since both A and its parent are in the "a" namespace. How can I select just B and C, that is, the shallowest children matching the namespace? Thanks. Note, this is XPath 1.0 (.NET 2), so I can't use in-scope-prefixes (which it appears would help).
