  • XML/C#: Read content if only if attribute is correct

    - by Zach
    Hi Guys, I have an XML file as follows, and I'm trying to read the content of the Name tag, only if the attribute of the Record tag is what I want. (continued below code) The XML file is: <?xml version="1.0" encoding="utf-8" ?> <Database> <Record Number="1"> <Name>John Doe</Name> <Position>1</Position> <HoursWorked>290</HoursWorked> <LastMonthChecked>0310</LastMonthChecked> </Record> <Record Number="2"> <Name>Jane Doe</Name> <Position>1</Position> <HoursWorked>251</HoursWorked> <LastMonthChecked>0310</LastMonthChecked> </Record> </Database> This is the C# code I have so far: public static string GetName(int EmployeeNumber) { XmlTextReader DataReader = new XmlTextReader("Database.xml"); DataReader.MoveToContent(); while (DataReader.Read()) { if (DataReader.NodeType == XmlNodeType.Element && DataReader.HasAttributes && DataReader.Name == "Record") { DataReader.MoveToAttribute(EmployeeNumber); DataReader.MoveToContent(); if (DataReader.NodeType == XmlNodeType.Element && DataReader.Name == "Name") { return DataReader.ReadContentAsString(); } } } } So for example, if 2 is passed to the function, I want it to return the string "Jane Doe". I'm new to XML parsing, so any help would be appreciated. Thanks.

  • Xpath fails if an element has a a xmlns attribute

    - by Callum Lamb
    Im trying to use xml to parse a .COLLADA file. The problem is I can't seem to use xpath() to access elements if the root tag has a xmlns attribute. For example this works: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); But this doesn't: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); How does the xmlns suddenly make the xml tree unusable? I thought it just defined the namespace so you could tell it apart from other identical tags in other namespaces. What am I missing?

  • How to change attribute on Scala XML Element

    - by Dave
    I have an XML file that I would like to map some attributes of in with a script. For example: <a> <b attr1 = "100" attr2 = "50"> </a> might have attributes scaled by a factor of two: <a> <b attr1 = "200" attr2 = "100"> </a> This page has a suggestion for adding attributes but doesn't detail a way to map a current attribute with a function (this way would make that very hard): http://www.scalaclass.com/book/export/html/1 What I've come up with is to manually create the XML (non-scala) linked-list... something like: // a typical match case for running thru XML elements: case Elem(prefix, e, attributes, scope, children @ _*) => { var newAttribs = attributes for(attr <- newAttribs) attr.key match { case "attr1" => newAttribs = attribs.append(new UnprefixedAttribute("attr1", (attr.value.head.text.toFloat * 2.0f).toString, attr.next)) case "attr2" => newAttribs = attribs.append(new UnprefixedAttribute("attr2", (attr.value.head.text.toFloat * 2.0f).toString, attr.next)) case _ => } Elem(prefix, e, newAttribs, scope, updateSubNode(children) : _*) // set new attribs and process the child elements } Its hideous, wordy, and needlessly re-orders the attributes in the output, which is bad for my current project due to some bad client code. Is there a scala-esque way to do this?

  • Applying the Hibernate filter attribute to a Bag with a many-to-many relationship

    - by David P
    Consider the following Hibernate mapping file: <hibernate-mapping ...> <class name="ContentPackage" table="contentPackages"> <id name="Id" column="id" type="int"><generator class="native" /></id> ... <bag name="Clips" table="contentAudVidLinks"> <key column="fk_contentPackageId"></key> <many-to-many class="Clip" column="fk_AudVidId"></many-to-many> <filter name="effectiveDate" condition=":asOfDate BETWEEN startDate and endDate" /> </bag> </class> </hibernate-mapping> When I run the following command: _session.EnableFilter("effectiveDate").SetParameter("asOfDate", DateTime.Today); IList<ContentPackage> items = _session.CreateCriteria(typeof(ContentPackage)) .Add(Restrictions.Eq("Id", id)) .List<ContentPackage>(); The resulting SQL has the WHERE clause on the intermediate mapping table (contentAudVidLinks), rather than the "Clips" table even though I have added the filter attribute to the Bag of Clips. What am I doing wrong?

  • Cannot get new product attribute in grid display

    - by russjman
    I added a new attribute to my products(a boolean "yes/no" field). It is a variable to enable/disable the price from displaying on the product detail page, and grid view. I managed to get it work on the product info page. But on product grid page I cant seem to access that variable. Specifically, the template i am working with is catalog/product/price.phtml. From what i can tell, the price is being displayed by the same group of if-statements on both the product detail page, and grid page. This has me confused because i cant find any code on that template to handle multiple products, just a bunch of nested if statements. this is how im attempting to access this new variable using $_displayPrice. on line 36 of catalog/product/price.html <?php $_product = $this->getProduct(); ?> <?php $_id = $_product->getId() ?> <?php $_displayPrice = $_product->getDisplayPrice() ? "Yes" : "No"; echo $_displayPrice;?> What has me further confused is that when display $_product-getData(), my new variable isn't anywhere among that data. thanks in advance

  • Suppressing PostSharp Multicast with Attribute

    - by Dan Bryant
    I've recently started experimenting with PostSharp and I found a particularly helpful aspect to automate implementation of INotifyPropertyChanged. You can see the example here. The basic functionality is excellent (all properties will be notified), but there are cases where I might want to suppress notification. For instance, I might know that a particular property is set once in the constructor and will never change again. As such, there is no need to emit the code for NotifyPropertyChanged. The overhead is minimal when classes are not frequently instantiated and I can prevent the problem by switching from an automatically generated property to a field-backed property and writing to the field. However, as I'm learning this new tool, it would be helpful to know if there is a way to tag a property with an attribute to suppress the code generation. I'd like to be able to do something like this: [NotifyPropertyChanged] public class MyClass { public double SomeValue { get; set; } public double ModifiedValue { get; private set; } [SuppressNotify] public double OnlySetOnce { get; private set; } public MyClass() { OnlySetOnce = 1.0; } }

  • 'NoneType' object has no attribute 'data'

    - by Bill Jordan
    Hello guys, I am sending a SOAP request to my server and getting the response back. sample of the response string is shown below: <?xml version = '1.0' ?> <env:Envelope xmlns:env=http:////www.w3.org/2003/05/soap-envelop . .. .. <env:Body> <epas:get-all-config-resp xmlns:epas="urn:organization:epas:soap"> ^M ... ... <epas:property name="Tom">12</epas:property> > > <epas:property name="Alice">34</epas:property> > > <epas:property name="John">56</epas:property> > > <epas:property name="Danial">78</epas:property> > > <epas:property name="George">90</epas:property> > > <epas:property name="Luise">11</epas:property> ... ^M </env:Body? </env:Envelop> What I noticed in the response is that there is an extra character shown in the body which is "^M". Not sure if this could be the issue. Note the ^M shown! when I tried parsing the string returned from the server to get the names and values using the code sample: elements = minidom.parseString(xmldoc).getElementsByTagName("property") myDict = {} for element in elements: myDict[element.getAttribute('name')] = element.firstChild.data But, I am getting this error: 'NoneType' object has no attribute 'data'. May be its something to do with the "^M" shown on the xml response back! Any ideas/comments would be appreciated, Cheers

  • Give a reference to a python instance attribute at class definition

    - by Guenther Jehle
    I have a class with attributes which have a reference to another attribute of this class. See class Device, value1 and value2 holding a reference to interface: class Interface(object): def __init__(self): self.port=None class Value(object): def __init__(self, interface, name): self.interface=interface self.name=name def get(self): return "Getting Value \"%s\" with interface \"%s\""%(self.name, self.interface.port) class Device(object): interface=Interface() value1=Value(interface, name="value1") value2=Value(interface, name="value2") def __init__(self, port): self.interface.port=port if __name__=="__main__": d1=Device("Foo") print d1.value1.get() # >>> Getting Value "value1" with interface "Foo" d2=Device("Bar") print d2.value1.get() # >>> Getting Value "value1" with interface "Bar" print d1.value1.get() # >>> Getting Value "value1" with interface "Bar" The last print is wrong, cause d1 should have the interface "Foo". I know whats going wrong: The line interface=Interface() line is executed, when the class definition is parsed (once). So every Device class has the same instance of interface. I could change the Device class to: class Device(object): interface=Interface() value1=Value(interface, name="value1") value2=Value(interface, name="value2") def __init__(self, port): self.interface=Interface() self.interface.port=port So this is also not working: The values still have the reference to the original interface instance and the self.interface is just another instance... The output now is: >>> Getting Value "value1" with interface "None" >>> Getting Value "value1" with interface "None" >>> Getting Value "value1" with interface "None" So how could I solve this the pythonic way? I could setup a function in the Device class to look for attributes with type Value and reassign them the new interface. Isn't this a common problem with a typical solution for it? Thanks!

  • Selecting a div with same ID as the rel attribute of clicked link

    - by Chris
    Hi there, This is a two-part question. I'm using jQuery for a project and wanting to click a link and toggle the class name "highlight" to that link and also to the div with the same id as the rel attribute of the link. I then want to be able to link to the next div without the classname of "highlight". Here's the HTML for it: <ul> <li><a href="#" rel="panel1">Item 1</a></li> <li><a href="#" rel="panel2">Item 2</a></li> <li><a href="#" rel="panel3">Item 3</a></li> </ul> <a href="">go to next div without class of highlight</a> <div id="panel1">some text</div> <div id="panel2">some text</div> <div id="panel3">some text</div> Can anyone help with jQuery side of things? Many thanks in advance!

  • IE ignores added onclick attribute

    - by user357034
    The Jquery code below works ok with firefox, Safari, Opera but not with IE. I kinda know why this isn't working in IE after reading a lot about it but I do not know how to fix it. My understanding (I think) is that this method will assign a attribute of "onclick" in IE rather than an event method. Therefore it will not fire in IE and the href fires instead which in this case is "#" which is exactly what is happening. What is the correct way of adding the onclick event. <a id="product_photo_zoom_url" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"><img id="product_photo" src="/v/vspfiles/photos/9857-116-003-2T.jpg" border="0" alt="9857-116-003 Ignition box" /></a> <br /><a id="product_photo_zoom_url2" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"> <img src="/v/vspfiles/templates/100/images/buttons/btn_largerphoto.gif" border="0"></a> var global_URL_Encode_Current_ProductCode; var global_Config_ProductPhotosFolder; var global_Current_ProductCode; var titleattr = $("a#product_photo_zoom_url").attr("title"); var picurl='tb_show(titleattr, \'/PhotoDetails.asp?ShowDESC=N&ProductCode=\' + global_URL_Encode_Current_ProductCode + \'&TB_iframe=true&height=600&width=520\');return false;' $("a#product_photo_zoom_url").attr('onclick', picurl); $("a#product_photo_zoom_url").attr('href', '#'); $("a#product_photo_zoom_url2").attr('onclick', picurl); $("a#product_photo_zoom_url2").attr('href', '#');

  • XSD: Different sub-elements depending on attribute/element value

    - by AndiDog
    Another XSD question - how can I achieve that the following XML elements are both valid: <some-element> <type>1</type> <a>...</a> </some-element> <some-element> <type>2</type> <b>...</b> </some-element> The sub-elements (either <a> or <b>) should depend on the content of <type> (could also be an attribute). It would be so simple in RelaxNG - but RelaxNG doesn't support key integrity :( Is there a way to implement this in XSD? Note: XML schema version 1.1 supports <xs:alternative>, which might be a solution, but afaik no reference implementation (e.g. libxml2) supports this yet. So I'm searching for workarounds. The only way I've come up with is: <type>1</type> <some-element type="1"> <!-- simple <xs:choice> between <a> and <b> goes here --> <a>...</a> </some-element> <!-- and now create a keyref between <type> and @type -->

  • [Rails] checkbox to update attribute

    - by Jeff
    [Updated a bit] I have a Task model that has a :completed boolean attribute. If I click on it I want it to execute the 'finish' method. The main problem is that I am displays a series of checkboxes in a list and subsequent checkboxes after the first one are ignored. The method is never called for the given task/checkbox combo. I have this chunk of code in my view: <% current_user.tasks.each do |t|%> <% if t.completed == false %> <%= check_box_tag :completed, true, checked = false %> <%= observe_field :completed, :url => { :controller => 'tasks', :action => :finish , :id => t.id }, :frequency => 0.25, :update => :completed, :with => true %> and my finish method looks like this: def finish @task = Task.find(params[:id]) new = {:completed => true} @task.update_attributes(new) render :update do |page| page.replace_html "taskListing", :partial => 'home/task_listing' end

  • Howto: Access a second related model in a nested attribute builder block

    I have a basic has_many through relationship: class Foo < ActiveRecord::Base has_many :bars, :dependent => :destroy has_many :wtfs :through => :bars accepts_nested_attributes_for :bars, :wtfs end On my crud forms I have a builder block for the wtf, but I need the label to come from the bar (an attribute called label for instance).

  • Apply [ThreadStatic] attribute to a method in external assembly

    - by Sen Jacob
    Can I use an external assembly's static method like [ThreadStatic] method? Here is my situation. The assembly class (which I do not have access to its source) has this structure public class RegistrationManager() { private RegistrationManager() {} public static void RegisterConfiguration(int ID) {} public static object DoWork() {} public static void UnregisterConfiguration(int ID) {} } Once registered, I cannot call the DoWork() with a different ID without unregistering the previously registered one. Actually I want to call the DoWork() method with different IDs simultaneously with multi-threading. If the RegisterConfiguration(int ID) method was [ThreadStatic], I could have call it in different threads without problems with calls, right? So, can I apply the [ThreadStatic] attribute to this method or is there any other way I can call the two static methods same time without waiting for other thread to unregister it? If I check it like the following, it should work. for(int i=0; i < 10; i++) { new Thread(new ThreadStart(() => Checker(i))).Start(); } public string Checker(int i) { public static void RegisterConfiguration(i); // Now i cannot register second time public static object DoWork(i); Thread.Sleep(5000); // DoWork() may take a little while to complete before unregistered public static void UnregisterConfiguration(i); }

  • Changing the href attribute on hover with jQuery

    - by AverageJoe
    Ok, I have an html page that is loaded into another html page via PHP (ok so its a PHP page, whatever). The page that is loaded is a list of hyperlinks. I need to change the href attribute to make the hyperlinks relative to the location of the stored images they refer too. When i load the page containing the hyperlinks the links are relative to the web host server, not the server that the page is actually hosted from. Somthing like this: <div #screenshots) <p><a href="image1.htm">Image1</a></p> <p><a href="image2.htm">Image2</a></p> <p><a href="image3.htm">Image3</a></p> <p><a href="image4.htm">Image4</a></p> <p><a href="image5.htm">Image5</a></p> </div> When I mouse over the links, the status bar shows the reference as "http://webHostServer.com/image1.htm". If I click it I get a 404 error. I need the href to change to something like this when I mouse over it: "http://www.actualImageHostServerIPaddress/image1.htm" I looked at this for assitance and came out with the following jQuery code, but for some reason none of it works: $(document).ready(function(){ $("button").click(function() { $("#screenshots a").addClass('ss'); }); $(".ss").each(function() { $(this).data("oldHref", $(this).attr("href")); orig = $(this).attr("href"); over = "http://208.167.244.33/208.167.244.33/"; $(this).hover(function() { $(this).attr("href", $(this).attr("href").replace(orig, over+orig)); }, function() { $(this).attr("href", $(this).data("oldHref")); }); }); When I click the button it dosen't add the class to the anchor tags, so when I hover over them nothing changes. Any help here would be great.

  • Enum.TryParse with Flags attribute

    - by Sunny
    I have written code to TryParse enum either by value or by its name as shown below. How can I extend this code to include parsing enums with Flags attribute? public static bool TryParse<T>(this T enum_type, object value, out T result) where T : struct { return enum_type.TryParse<T>(value, true, out result); } public static bool TryParse<T>(this T enum_type, object value, bool ignoreCase, out T result) where T : struct { result = default(T); var is_converted = false; var is_valid_value_for_conversion = new Func<T, object, bool, bool>[]{ (e, v, i) => e.GetType().IsEnum, (e, v, i) => value != null, (e, v, i) => Enum.GetNames(e.GetType()).Any(n => String.Compare(n, v.ToString(), i) == 0) || Enum.IsDefined(e.GetType(), v) }; if(is_valid_value_for_conversion.All(rule => rule(enum_type, value, ignoreCase))){ result = (T)Enum.Parse(typeof(T), value.ToString(), ignoreCase); is_converted = true; } return is_converted; } Currently this code works for the following enums: enum SomeEnum{ A, B, C } // can parse either by 'A' or 'a' enum SomeEnum1 : int { A = 1, B = 2, C = 3 } // can parse either by 'A' or 'a' or 1 or "1" Does not work for: [Flags] enum SomeEnum2 { A = 1, B = 2, C = 4 } // can parse either by 'A' or 'a' // cannot parse for A|B Thanks!

  • Issue with changing an attribute with jquery

    - by rshivers
    Hello, I'm having an issue with changing the attribute for an id and can't seem to figure out what I'm doing wrong. I guess it doesn't help that I'm new to this also. I have a function that tests to make sure that I am pulling the correct id from the row in my form that I have dynamically created. It goes something like this: myFunction() { var id = $(id).attr("id"); alert("This is my id " + id); } This works with no problem and when I click the button assigned to alert me of my id it will give give me the id of the dynamic row in my form. The issue is now when I try to change the id with this: changeId() { var newId = $(id).attr("id", "x"); alert("This is my new id " + newId); } What happens in this case is that it will alert saying "This is my new id [object Object]" instead of giving me the new id. Any suggestions? I'd really appreciate any help with this.

  • Laravel4: Checking many-to-many relationship attribute even when it does not exist

    - by Simo A.
    This is my first time with Laravel and also Stackoverflow... I am developing a simple course management system. The main objects are User and Course, with a many-to-many relationship between them. The pivot table has an additional attribute, participant_role, which defines whether the user is a student or an instructor within that particular course. class Course extends Eloquent { public function users() { return $this->belongsToMany('User')->withPivot('participant_role')->withTimestamps(); } } However, there is an additional role, system admin, which can be defined on the User object. And this brings me mucho headache. In my blade view I have the following: @if ($course->pivot->participant_role == 'instructor') { // do something here... } This works fine when the user has been assigned to that particular $course and there is an entry for this user-course combination in the pivot table. However, the problem is the system administrator, who also should be able to access course details. The if-clause above gives Trying to get property of non-object error, apparently because there is no entry in the pivot table for system administrator (as the role is defined within the User object). I could probably solve the problem by using some off-the-shelf bundle for handling role-based permissions. Or I could (but don't want to) do something like this with two internal if-clauses: if (!empty($course->pivot)) { if ($course->pivot->participant_role == 'instructor') { // do something... } } Other options (suggested in partially similar entries in Stackoverflow) would include 1) reading all the pivot table entries to an array, and use in_array to check if a role exists, or even 2) SQL left join to do this on database level. However, ultimately I am looking for a compact one-line solution? Can I do anything similar to this, which unfortunately does not seem to work? if (! empty ($course->pivot->participant_role == 'instructor') ) { // do something... } The shorter the answer, the better :-). Thanks a lot!

  • Exclude notes based on attribute wildcard in XSL node selection

    - by C A
    Using cruisecontrol for continuous integration, I have some annoyances with Weblogic Ant tasks and how they think that server debug information are warnings rather than debug, so are shown in my build report emails. The XML output from cruise is similar to: <cruisecontrol> <build> <target name="compile-xxx"> <task name="xxx" /> </target> <target name="xxx.weblogic"> <task name="wldeploy"> <message priority="warn">Message which isn't really a warning"</message> </task> </target> </build> </cruisecontrol> In the cruisecontrol XSL template the current selection for the task list is: <xsl:variable name="tasklist" select="/cruisecontrol/build//target/task"/> What I would like is something which selects the tasklist in the same way, but doesn't include any target nodes which have the attribute name="*weblogic" where * is a wildcard. I have tried <xsl:variable name="tasklist" select="/cruisecontrol/build//target[@name!='*weblogic']/task"/> but this doesn't seem to have worked. I'm not an expert with XSLT, and just want to get this fixed so I can carry on the real development of the project. Any help is much appreciated.
