• T-SQL XML Query, how to seperate matching nodes into individual rows?

  - by FlySwat

  I have a table that has a column full of XML like: <parent> <child> <name>Sally</name> </child> <child> <name>Bobby</name> </child> </parent> I'm trying to extract all of the names of the children into seperate rows. My desired resultset would look like: Sally Bobby However, if I do something like: SELECT data.query('data(//parents/child/name)') FROM stuff I get back a single row that looks like Sally Bobby What am I doing wrong with the XPath?

• TextView defined in main.xml - how to "name" it to be able to use - setText() method?

  - by Oliver Goossens

  Hi, I am exploring android and developement and I found one problem. My app UI is defined in main.xml I have 2 texts and 2 buttons defined - easy app. I read that I may be able to change TEXT in the ACTIVITY using the setText() method. And thats the problem - how do I POINT the setText() Method? How do I tell it to change a specified text? If I would declare the TextView inside the Activity with NEW TextView NAME Object, I would just need to use NAME.setText(STRING)... But I didnt so i dont have anything like NAME of the object? How can this be done? I read something about r.IDs but I truly dont have a idea how to use them, where to find them and how to implement it .... Please advise Thank you Oliver

• XML Table layout? Two EQUAL-width rows filled with equally width buttons??

  - by Oliver Goossens

  Hi heres a part from my XML for LAND format: <TableLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" android:stretchColumns="*"> <TableRow> <Button android:id="@+id/countbutton" android:text="@string/plus1"/> <Button android:id="@+id/resetbutton" android:text="@string/reset" /> </TableRow> </TableLayout> And now what I dont get - the WIDTH of one row and also of the button depends on the TEXT inside the button. If the both texts are equaly long lets say : TEXT its ok - the table half is in the middle of the screen. But if they have different size - lets say "A" and "THIS IS THE LONG BUTTON" the CENTER of the table isnt in the middle of the screen anymore and so the buttons are not equally width... Cant find any solution... Please advise... Thank you Oliver Goossens

• .NET WebService Custom Attribute

  - by DownChapel

  I would like to add a custom attribute to a asmx web service to determine if the request is valid based on the client IP address. This is a similar idea to the AuthorizeAttribute in ASP.NET MVC. Is there anywhere (e.g. a HTTP module) I can put the code to look at the attribute on the webservice and decide whether to allow the request or not? In my web.config the handler for asmx is the ScriptHandlerFactory from the System.Web.Extensions dll. I have already implemented the functionality with a HTTP module and a config file with a list of allowed URLs, but I would prefer to get rid of the config file and just add an attribute to the webservice class. Thanks

• Proper usage (best practices) of Browsable attribute in .NET for runtime grid component behavior

  - by Dan

  I understand how Browsable attribute is supposed to work. It's supposed to hide a property from showing up in a PropertyGrid in design time. It also has another effect in that it will stop a Property from showing up in components such as Grids, or specifically Infragistics WinGrid. I am not sure if it has this behaviour on regular Windows Forms grids. This works, but it doesn't sound like Browsable is being use as intended when being used for 'Run time' displaying of a property on a grid component. Any literature from Microsoft on proper use. Even though it works, I don't want to use this attribute to hide columns on a grid bound to a business object if it's not indeed the correct usage of the attribute, but rather something some grid vendors decided to use to determine property visibility on their grids.

• Custom XML Serialization, how to write custom root element?

  - by Beta033

  I'm probably just doing this wrong, i know. i'm using custom serialization and when the xml is generated it's putting the class name as the root element Example: <MyClassName> <MyIntendedRootNode> <ObjectType> <Property1/> <Property2/> ... I'm inoking the serialization by calling xmlserializer.Serialize(writer,Me) so i'm sure that has something to do with it. I've tried putting XMLRoot onto the class, but i think as vb is compiling this partial class with it's aspx page, it's either overwriting this property or ignoring it entirely. ideally i'd like to just tell it to either throw away everything it has and use a different root element. Anybody else do this except me? Thanks

• how to get namespace prefixes from XML document, using MSXML ?

  - by KaluSingh Gabbar

  For example, In this document < ?xml version="1.0" ? > < SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns1="http://opcfoundation.org/webservices/XMLDA/1.0/" xmlns:ns2="Service"> < SOAP-ENV:Body id="_0" > if I need to select the element "Body", I need to know the prefix "SOAP-ENV". How can I get that? getting a root element and slicing the colon (:) off seems a dirty idea to me, I am sure there should be a neat way to do that. Google does not help (may be I am not searching for the right thing).

• Blog Engine .NET with XML Data Storage How is it so fast ?

  - by Kubi

  I am looking for a way to embed a blog engine into my own application and I am too curious about Blog Engine algorithm. This may not be the correct place to ask but, How is that possible to store blog entry data in an XML file like BlogEngine.Net with Default Configuration. It must be getting slower everyday while the file is getting larger and larger. I am wondering the algorithm behind that. Is it loading with a different way ? Or Am I wrong with the time estimation ? I know it is open source but I thought it would be better to see a discussion here for some others might be thinking the same and this thread can be a reference.

• How can I convert convert docx or wordml xml files to xsl-fo?

  - by Jon Pastore

  I've been looking for a method to convert docx or wordml xml to xsl-fo. I read this post: http://stackoverflow.com/questions/156683/what-is-the-best-xslt-engine-for-perl but I'm having exceptional problems getting apache-fop going. I was able to download the bins and run it locally but the formatting was a little off and it didn't maintain the headers and footers or section 1 or section 3 (17 page doc 3 sections) it also overlapped the text over the outline numbers and did not maintain the font used. trying a more simple test caused fop to fail completely. I would like to find a way to create a PDF that is at least close to 100% accurate reproduction of the original doc.

• SOAP, REST or just XML for Objective-C/iPhone vs. server solution

  - by Nicsoft

  Hello, We are going to set up a solution where the iPhone is requesting data from the server. We have the option to decide what kind of solution to put in place and we are not sure about which way to go. Regarding SOAP I think I have the answer, there are no really stable solution for doing this (I know there are solutions, but I want something stable). How about REST? Or is it better to just create our own XML? It's not going to be so complicated reguest/respons-flow. Thanks in advance!

• XPath select an attribute based on value

  - by Apeksha

  Using VB.Net, I have an XmlNode object, xNode. I need to select an attribute of this node if it has a particular value. e.g. xNode.SelectSingleNode(".[@attr1='1']") I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set. When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']") It always returns Nothing, even if the attribute has a value of 1. I have tried a lot of different things, but no luck yet. Please help. Thanks.

• What is resource-ref in web.xml used for?

  - by Denise

  Hi everyone, I'm just wondering when/why you would define a resource-ref element in your web.xml file? I would have thought that it would be defined in your web/app server using JNDI and then look up the JNDI reference in your Java code? The resource-ref definition seems a bit redundant to me and I can't think of when it might be useful. Example: <resource-ref> <description>Primary database</description> <res-ref-name>jdbc/primaryDB</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>CONTAINER</res-auth> </resource-ref> Thanks!

• python object AttributeError: type object 'Track' has no attribute 'title'

  - by ccwhite1

  I apologize if this is a noob question, but I can't seem to figure this one out. I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem) class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest I use ObjectListView to create a list of tracks in a specific directory ....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... Now I want to iterate the list and print out a single value of each item list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle This fails with the error AttributeError: type object 'Track' has no attribute 'atrTitle' What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item list = self.TrackOlv.GetSelectedObject() print list.atrTitle

• Creating a list of integers in XML for android.

  - by Leif Andersen

  I would like to create a list of Integers in the /res folder of an android project. However, I want those integers to point resources in /res/raw. So for example, I would like something like this: <?xml version="1.0" encoding="utf-8"?> <resources> <integer-array name="built_in_sounds"> <item>@raw/sound</item> </integer-array> </resources> But id doesn't look like I can do that, is there any way to do this? Or should I just create the list in a java class? Thank you

• ASP MVC: Custom Validation Attribute

  - by user323395

  I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

• Attribute lost with yield

  - by Nelson

  Here's an interesting one... There is some code that I'm trying to convert from IList to IEnumerable: [Something(123)] public IEnumerable<Foo> GetAllFoos() { SetupSomething(); DataReader dr = RunSomething(); while (dr.Read()) { yield return Factory.Create(dr); } } The problem is, SetupSomething() comes from the base class and uses: Attribute.GetCustomAttribute(new StackTrace().GetFrame(1).GetMethod(), typeof(Something)) Yield ends up creating MoveNext(), MoveNext() calls SetupSomething(), and MoveNext() does not have the [Something(123)] attribute. I can't change the base class, so it appears I am forced to stay with IList or implement IEnumerable manually (and add the attribute to MoveNext()). Is there any other way to make yield work in this scenario?

• A reasonable way to add attributes to an xml root element.

  - by DrLazer

  The function "WriteStartElement" does not return anything. I find this a little bizzare. So up until now I have been doing it like this. XmlDocument xmlDoc = new XmlDocument(); XmlTextWriter xmlWriter = new XmlTextWriter(m_targetFilePath, System.Text.Encoding.UTF8); xmlWriter.Formatting = Formatting.Indented; xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'"); xmlWriter.WriteStartElement("client"); xmlWriter.Close(); xmlDoc.Load(m_targetFilePath); XmlElement root = xmlDoc.DocumentElement; Saving the doc, then reloading it to get hold of the start element so i can write attributes to it. Does anybody know the correct way of doing this because I'm pretty sure what I'm doing isn't right. I tried to use xmlWriter.AppendChild() but it doesnt seem to write out anything. :(

• DebuggerDisplay attribute does not work as expected!

  - by mark

  Dear ladies and sirs. I know that this attribute should work in C# and yet, in my case it does not. I have a class with a lazy property Children. Accessing this property may have a side effect of roundtripping to the server. So, naturally, I do not want this to happen when I just watch it in the debugger watch window. Omitting all the irrelevant details the source looks pretty ordinary: [DebuggerDisplay("(Frozen) {m_children}")] public IList<IEntityBase> Children { get { if (m_children == null) { m_children = FetchChildrenFromDB(this); } return m_children; } } And yet, when I watch the object and expand this in the watch window I do not see (Frozen) in the display, meaning the debugger simply ignores the attribute. Provided the image link is still valid it should be visible below: http://i28.tinypic.com/2zxo9s5.jpg The attribute is really there, according to Reflector. I use VS2008. Any ideas?

• How to efficiently replace characters in XML document in Java?

  - by Pregzt

  I'm looking for a neat and efficient way to replace characters in XML document. There is a replacement table defined for almost 12.000 UTF-8 characters, most of them are to be replaced by single characters, but some must be replaced by two or even three characters (e.g. Greek theta should become TH). The documents can be bulky (100MB+). How to do it in Java? I came up with the idea of using XSLT, but I'm not too sure if this is the best option.

• Find HTML based on partial attribute

  - by Kirean

  Is there a way with javascript (particularly jQuery) to find an element based on a partial attribute name? I am not looking for any of the selectors that find partial attribute values as referenced in these links: starts with [name^="value"] contains prefix [name|="value"] contains [name*="value"] contains word [name~="value"] ends with [name$="value"] equals [name="value"] not equal [name!="value"] starts with [name^="value"] but more something along the lines of <div data-api-src="some value"></div> <div data-api-myattr="foobar"></div> and $("[^data-api]").doSomething() to find any element that has an attribute that starts with "data-api".

• In Log4Net XML configuration is Priority the same thing as Level?

  - by Michael Levy

  I inherited some code that uses the priority element under the root in its xml configuraiton. This is just like the example at http://iserialized.com/log4net-for-noobs/ which shows: <root> <priority value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="ConsoleAppender"/> </root> However, the log4net configuration examples at http://logging.apache.org/log4net/release/manual/configuration.html always show it using the level element: <root> <level value="DEBUG" /> <appender-ref ref="A1" /> </root> In this type of configuration is <priority> the same as <level> ? Can someone point me to somewhere in the docs where this is explained?

• What are the advantages to use StringBuilder versus XmlDocument or related to create XML documetns?

  - by Rob

  This might be a bit of a code smell, but I have seen it is some production code, namely the use of StringBuilder as opposed to XmlDocument when creating XML documents. In some cases these are write once operations (e.g. create the document and save it to disk) where as others are passing the built string to an XmlDocument to preform an XslTransform to a document that is returned to the client. So obvious question: is there merit to doing things this way, is it something that should be done on a case-by-case basis, or is this the wrong way of doing things?

• XML multiline comments in C# - what am I doing wrong?

  - by Dave

  According to this article, it's possible to get multiline XML comments -- instead of using ///, use /** */. This is my interpretation of what multiline comments are, and what I want to have happen: /** * <summary> * this comment is on line 1 in the tooltip * this comment is on line 2 in the tooltip * </summary> */ However, when I use this form, the tooltip that pops up when I hover over my class name in my code is single-line, i.e. it looks exactly as if I had written my comment like this: /// <summary> /// this comment is on line 1 in the tooltip /// this comment is on line 2 in the tooltip /// </summary> Is this behavior actually possible still in VS2008?
