• JBOSS Security: web.xml vs. jboss-web.xml

  - by sixtyfootersdude

  What is the relation between web.xml and jboss-web.xml? Seems like: Jboss-web.xml specifies the security domain (which can be found in login-config.xml) web.xml specifies what the security level is I don't understand what happens when jboss-web.xml specifies a weak security domain. Ie: one that cannot do what web.xml specifies. What happens then?

• Is xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" a special case in XML?

  - by Bytecode Ninja

  When we use a namespace, we should also indicate where its associated XSD is located at, as can be seen in the following example: <?xml version="1.0"?> <Artist BirthYear="1958" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.webucator.com/Artist" xsi:schemaLocation="http://www.webucator.com/Artist Artist.xsd"> <Name> <Title>Mr.</Title> <FirstName>Michael</FirstName> <LastName>Jackson</LastName> </Name> </Artist> Here, we have indicated that Artist.xsd should be used for validating the http://www.webucator.com/Artist namespace. However, we are also using the http://www.w3.org/2001/XMLSchema-instance namespace, but we have not specified where its XSD is located at. How do XML parsers know how to handle this namespace? Thanks in advance.

• Using XML as data storage

  - by Kian Mayne

  I was thinking about the XML format and the following quote: “XML is not a database. It was never meant to be a database. It is never going to be a database. Relational databases are proven technology with more than 20 years of implementation experience. They are solid, stable, useful products. They are not going away. XML is a very useful technology for moving data between different databases or between databases and other programs. However, it is not itself a database. Don't use it like one.“ -Effective XML: 50 Specific Ways to Improve Your XML by Elliotte Rusty Harold (page 230, Part 4, Item 41, 2nd paragraph) This seems to really stress that XML should not be used for data storage and should only be used for program to program interoperability. Personally, I disagree and .NET's app.config file that's used to store a program's settings is an example of data storage in an XML file. However for databases rather than configurations etc XML should not be used. To develop my point, I will use two examples: A) Data about customers with fields that are all on one level i.e. there are a number of fields all relating to one customer with no children B) Data about configuration of an application where nested fields and properties make a lot of sense So my question is, Is this still a valid statement and is it now acceptable to store data using XML? EDIT: I've sent an email to the author of that quote to ask for his input/extra context.

• What schema documentation tools exist for PostgreSQL

  - by Brad Koch

  MySQL has MySQL Workbench for designing and documenting your schema, and generates CREATE and ALTER scripts based on your design. We're looking at migrating to PostgreSQL in the near future, and we do need a practical way of documenting and modifying the schema structure. What similar tools exist for Postgres (that are OS X/Linux compatible)? Alternatively, what equivalent conventions would be followed for designing and documenting the structure of your Postgres database?

• Does searching documentation and samples look bad?

  - by Mick Aranha

  I am starting a new job in a company with many developers and media people, the layout of the place is open with computers around a skinny oval, I have worked in small teams and programming embedded C, the jobis for objective C I'm still in a medium stage, so I know what I don't know (haha), that means I have to google it and then implement it, So the question is how bad does it look if the guy next to you does lot of searching for coding I mean, at the end of the day I will get the job done, but want to look professional too!

• XML + Xslt -> Xml with PHP

  - by rokdd

  Hi, I know that there are really a mass of XML XSLT php merging threads at SO. But php specific i could not found what might my problem: $xml = new DOMDocument; $xml-load("f.xml"); $xsl = new DOMDocument; $xsl-load('test.xsl'); // init and configure processor $proc = new XSLTProcessor; $proc-importStyleSheet($xsl); // import xsl document $xml2=$proc-transformToXML($xml); echo $xml2; My xslt file looks a bit empty.. However i tried ´output method="xml"´. but it doesnot help.. PHP returns always the data as text or html but not in XML.. what i am doing wrong. I only want to edit the XML with xslt and save back to XML (file). THanks for your help!

• Perl XML SAX parser emulating XML::Simple record for record

  - by DVK

  Short Q summary: I am looking a fast XML parser (most likely a wrapper around some standard SAX parser) which will produce per-record data structure 100% identical to those produced by XML::Simple. Details: We have a large code infrastructure which depends on processing records one-by-one and expects the record to be a data structure in a format produced by XML::Simple since it always used XML::Simple since early Jurassic era. An example simple XML is: <root> <rec><f1>v1</f1><f2>v2</f2></rec> <rec><f1>v1b</f1><f2>v2b</f2></rec> <rec><f1>v1c</f1><f2>v2c</f2></rec> </root> And example rough code is: sub process_record { my ($obj, $record_hash) = @_; # do_stuff } my $records = XML::Simple->XMLin(@args)->{root}; foreach my $record (@$records) { $obj->process_record($record) }; As everyone knows XML::Simple is, well, simple. And more importantly, it is very slow and a memory hog - due to being a DOM parser and needing to build/store 100% of data in memory. So, it's not the best tool for parsing an XML file consisting of large amount of small records record-by-record. However, re-writing the entire code (which consist of large amount of "process_record"-like methods) to work with standard SAX parser seems like an big task not worth the resources, even at the cost of living with XML::Simple. What I'm looking for is an existing module which will probably be based on a SAX parser (or anything fast with small memory footprint) which can be used to produce $record hashrefs one by one based on the XML pictured above that can be passed to $obj->process_record($record) and be 100% identical to what XML::Simple's hashrefs would have been. I don't care much what the interface of the new module is - e.g whether I need to call next_record() or give it a callback coderef accepting a record.

• Generate HTML pages from some template

  - by Appu

  I have an open-source project for which I have to generate HTML pages to put on the web. I wanted to keep everything as simple HTML pages. The problem with this approach is if I need to change the design, I have to goto all the pages and change it. This will be tough as I have lot of pages. Is there some kind of HTML generators which can process simple annotated text files? This way, I can maintain the documentation and website contents as plain text files and run it through this program to generate static HTML pages. This also helps in keeping the design consistent. Any help would be great!

• How to document experimental or incomplete APIs like @deprecated?

  - by Michael Levy

  Is there a good term that is similar but different than "deprecate" to mean that a method or API is in the code base but should not be used because its implementation is not complete or will likely change? (Yeah, I know, those methods shouldn't be public, yada yada yada. I didn't create my situation, I'm just trying to make the best of it.) What do people suggest? Experimental, Incomplete, something else? If I'm building javadoc documentation for this API that is still in flux, should I use the @deprecated tag or is there a better convention? To me @deprecated implies that this API is old and a newer preferred mechanism is available. In my situation, there is no alternative, but some of the methods in the API are not finished and so should not be used. At this point I cannot make them private, but I'd like to put clear warnings in the docs.

• Loading class instance from XML with Texture2D

  - by Thegluestickman

  I'm having trouble with XML and XNA. I want to be able to load weapon settings through XML to make my weapons easier to make and to have less code in the actual project file. So I started out making a basic XML document, something to just assign variables with. But no matter what I changed it gave me a new error every time. The code below gives me a "XML element 'Tag' not found", I added and it started to say the variables weren't found. What I wanted to do in the XML file as well, was load a texture for the file too. So I created a static class to hold my texture values, then in the Texture tag of my XML document I would set it to that instance too. I think that's were the problems are occuring because that's where the "XML element 'Tag' not found" error is pointing me too. My XML document: <XnaContent> <Asset Type="ConversationEngine.Weapon"> <weaponStrength>0</weaponStrength> <damageModifiers>0</damageModifiers> <speed>0</speed> <magicDefense>0</magicDefense> <description>0</description> <identifier>0</identifier> <weaponTexture>LoadWeaponTextures.ironSword</weaponTexture> </Asset> </XnaContent> My Class to load the weapon XML: public class Weapon { public int weaponStrength; public int damageModifiers; public int speed; public int magicDefense; public string description; public string identifier; public Texture2D weaponTexture; } public static class LoadWeaponXML { static Weapon Weapons; public static Weapon WeaponLoad(ContentManager content, int id) { Weapons = content.Load<Weapon>(@"Weapons/" + id); return Weapons; } } public static class LoadWeaponTextures { public static Texture2D ironSword; public static void TextureLoad(ContentManager content) { ironSword = content.Load<Texture2D>("Sword"); } } I'm not entirely sure if you can load textures through XML, but any help would be greatly appreciated.

• XML documentation to context sensitive help

  - by Yonas

  These days a number of commercial and open source tools have been developed for this purpose. However(unfortunately), non of them meet my requirement for specific problem I am dealing with. Currently, I am working on a project that exposes a different classes and functions to user as scripting interface. the user can use the objects from custom scripting interface and call methods to solve some specific problem. The problem I am facing is users of my classes need some sort of documentation in order to write their script efficiently. To address this problem am planing to use the compiler generated XML file to provide context sensitive help, which allows users to mouse over on any of the controls and corresponding methods from the GUI and read the reference documentation of the class/method. Now ... here are my questions: Can I get the sample source code? Can any one give me someone point me to some sort of best approach to address the problem?

• VB.Net Validate an xml against a schema (strange problem)

  - by Apeksha

  I have written a small XML validator, that takes in an XML file and an XML schema and validates the XML files against that schema. It works well, except for an XML file, with this content: <?xml version="1.0" encoding="utf-8"?> <xc:program xmlns:xc="http:\\www.something.com\Schema\XC10" xc:version="4.0.22.0" > <xc:namespaceDecls> <xc:namespaceDecl xc:namespaceDeclURI="urn:swift:xsd:abc"> <xc:namespaceDeclPrefix>n</xc:namespaceDeclPrefix> </xc:namespaceDecl> </xc:namespaceDecls> </xc:program> I tried to validate this XML file against a bunch of different schemas. No matter which schema I select, this XML file comes out as valid. What is it that I am missing? Here is the relevant piece of code: 'Create a schema cache and add the given schema to it. Dim schemaCache As New Schema.XmlSchemaSet schemaCache.Add(targetNamespace, schemaFilename) 'Create an XML DOMDocument object. Dim xmlDom As New XmlDocument 'Assign the schema cache to the DOM document. 'schemas collection. xmlDom.Schemas = schemaCache 'Load selected file as the DOM document. xmlDom.Load(xmlFilename) xmlDom.Validate(AddressOf ValidationCallBack)

• An Xml Serializable PropertyBag Dictionary Class for .NET

  - by Rick Strahl

  I don't know about you but I frequently need property bags in my applications to store and possibly cache arbitrary data. Dictionary<T,V> works well for this although I always seem to be hunting for a more specific generic type that provides a string key based dictionary. There's string dictionary, but it only works with strings. There's Hashset<T> but it uses the actual values as keys. In most key value pair situations for me string is key value to work off. Dictionary<T,V> works well enough, but there are some issues with serialization of dictionaries in .NET. The .NET framework doesn't do well serializing IDictionary objects out of the box. The XmlSerializer doesn't support serialization of IDictionary via it's default serialization, and while the DataContractSerializer does support IDictionary serialization it produces some pretty atrocious XML. What doesn't work? First off Dictionary serialization with the Xml Serializer doesn't work so the following fails: [TestMethod] public void DictionaryXmlSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXml(bag)); } public string ToXml(object obj) { if (obj == null) return null; StringWriter sw = new StringWriter(); XmlSerializer ser = new XmlSerializer(obj.GetType()); ser.Serialize(sw, obj); return sw.ToString(); } The error you get with this is: System.NotSupportedException: The type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] is not supported because it implements IDictionary. Got it! BTW, the same is true with binary serialization. Running the same code above against the DataContractSerializer does work: [TestMethod] public void DictionaryDataContextSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXmlDcs(bag)); } public string ToXmlDcs(object value, bool throwExceptions = false) { var ser = new DataContractSerializer(value.GetType(), null, int.MaxValue, true, false, null); MemoryStream ms = new MemoryStream(); ser.WriteObject(ms, value); return Encoding.UTF8.GetString(ms.ToArray(), 0, (int)ms.Length); } This DOES work but produces some pretty heinous XML (formatted with line breaks and indentation here): <ArrayOfKeyValueOfstringanyType xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <KeyValueOfstringanyType> <Key>key</Key> <Value i:type="a:string" xmlns:a="http://www.w3.org/2001/XMLSchema">Value</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key2</Key> <Value i:type="a:decimal" xmlns:a="http://www.w3.org/2001/XMLSchema">100.10</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key3</Key> <Value i:type="a:guid" xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/">2cd46d2a-a636-4af4-979b-e834d39b6d37</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key4</Key> <Value i:type="a:dateTime" xmlns:a="http://www.w3.org/2001/XMLSchema">2011-09-19T17:17:05.4406999-07:00</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key5</Key> <Value i:type="a:boolean" xmlns:a="http://www.w3.org/2001/XMLSchema">true</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key7</Key> <Value i:type="a:base64Binary" xmlns:a="http://www.w3.org/2001/XMLSchema">Ki1C</Value> </KeyValueOfstringanyType> </ArrayOfKeyValueOfstringanyType> Ouch! That seriously hurts the eye! :-) Worse though it's extremely verbose with all those repetitive namespace declarations. It's good to know that it works in a pinch, but for a human readable/editable solution or something lightweight to store in a database it's not quite ideal. Why should I care? As a little background, in one of my applications I have a need for a flexible property bag that is used on a free form database field on an otherwise static entity. Basically what I have is a standard database record to which arbitrary properties can be added in an XML based string field. I intend to expose those arbitrary properties as a collection from field data stored in XML. The concept is pretty simple: When loading write the data to the collection, when the data is saved serialize the data into an XML string and store it into the database. When reading the data pick up the XML and if the collection on the entity is accessed automatically deserialize the XML into the Dictionary. (I'll talk more about this in another post). While the DataContext Serializer would work, it's verbosity is problematic both for size of the generated XML strings and the fact that users can manually edit this XML based property data in an advanced mode. A clean(er) layout certainly would be preferable and more user friendly. Custom XMLSerialization with a PropertyBag Class So… after a bunch of experimentation with different serialization formats I decided to create a custom PropertyBag class that provides for a serializable Dictionary. It's basically a custom Dictionary<TType,TValue> implementation with the keys always set as string keys. The result are PropertyBag<TValue> and PropertyBag (which defaults to the object type for values). The PropertyBag<TType> and PropertyBag classes provide these features: Subclassed from Dictionary<T,V> Implements IXmlSerializable with a cleanish XML format ToXml() and FromXml() methods to export and import to and from XML strings Static CreateFromXml() method to create an instance It's simple enough as it's merely a Dictionary<string,object> subclass but that supports serialization to a - what I think at least - cleaner XML format. The class is super simple to use: [TestMethod] public void PropertyBagTwoWayObjectSerializationTest() { var bag = new PropertyBag(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42,45,66 } ); bag.Add("Key8", null); bag.Add("Key9", new ComplexObject() { Name = "Rick", Entered = DateTime.Now, Count = 10 }); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag["key"] as string == "Value"); Assert.IsInstanceOfType( bag["Key3"], typeof(Guid)); Assert.IsNull(bag["Key8"]); //Assert.IsNull(bag["Key10"]); Assert.IsInstanceOfType(bag["Key9"], typeof(ComplexObject)); } This uses the PropertyBag class which uses a PropertyBag<string,object> - which means it returns untyped values of type object. I suspect for me this will be the most common scenario as I'd want to store arbitrary values in the PropertyBag rather than one specific type. The same code with a strongly typed PropertyBag<decimal> looks like this: [TestMethod] public void PropertyBagTwoWayValueTypeSerializationTest() { var bag = new PropertyBag<decimal>(); bag.Add("key", 10M); bag.Add("Key1", 100.10M); bag.Add("Key2", 200.10M); bag.Add("Key3", 300.10M); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag.Get("Key1") == 100.10M); Assert.IsTrue(bag.Get("Key3") == 300.10M); } and produces typed results of type decimal. The types can be either value or reference types the combination of which actually proved to be a little more tricky than anticipated due to null and specific string value checks required - getting the generic typing right required use of default(T) and Convert.ChangeType() to trick the compiler into playing nice. Of course the whole raison d'etre for this class is the XML serialization. You can see in the code above that we're doing a .ToXml() and .FromXml() to serialize to and from string. The XML produced for the first example looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value>Value</value> </item> <item> <key>Key2</key> <value type="decimal">100.10</value> </item> <item> <key>Key3</key> <value type="___System.Guid"> <guid>f7a92032-0c6d-4e9d-9950-b15ff7cd207d</guid> </value> </item> <item> <key>Key4</key> <value type="datetime">2011-09-26T17:45:58.5789578-10:00</value> </item> <item> <key>Key5</key> <value type="boolean">true</value> </item> <item> <key>Key7</key> <value type="base64Binary">Ki1C</value> </item> <item> <key>Key8</key> <value type="nil" /> </item> <item> <key>Key9</key> <value type="___Westwind.Tools.Tests.PropertyBagTest+ComplexObject"> <ComplexObject> <Name>Rick</Name> <Entered>2011-09-26T17:45:58.5789578-10:00</Entered> <Count>10</Count> </ComplexObject> </value> </item> </properties>   The format is a bit cleaner than the DataContractSerializer. Each item is serialized into <key> <value> pairs. If the value is a string no type information is written. Since string tends to be the most common type this saves space and serialization processing. All other types are attributed. Simple types are mapped to XML types so things like decimal, datetime, boolean and base64Binary are encoded using their Xml type values. All other types are embedded with a hokey format that describes the .NET type preceded by a three underscores and then are encoded using the XmlSerializer. You can see this best above in the ComplexObject encoding. For custom types this isn't pretty either, but it's more concise than the DCS and it works as long as you're serializing back and forth between .NET clients at least. The XML generated from the second example that uses PropertyBag<decimal> looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value type="decimal">10</value> </item> <item> <key>Key1</key> <value type="decimal">100.10</value> </item> <item> <key>Key2</key> <value type="decimal">200.10</value> </item> <item> <key>Key3</key> <value type="decimal">300.10</value> </item> </properties>   How does it work As I mentioned there's nothing fancy about this solution - it's little more than a subclass of Dictionary<T,V> that implements custom Xml Serialization and a couple of helper methods that facilitate getting the XML in and out of the class more easily. But it's proven very handy for a number of projects for me where dynamic data storage is required. Here's the code: /// <summary> /// Creates a serializable string/object dictionary that is XML serializable /// Encodes keys as element names and values as simple values with a type /// attribute that contains an XML type name.

The code implements ReadXml and WriteXml for the IXmlSerializable implementation using old school XmlReaders and XmlWriters (because it's pretty simple stuff - no need for XLinq here). Then there are two helper methods .ToXml() and .FromXml() that basically allow your code to easily convert between XML and a PropertyBag object. In my code that's what I use to actually to persist to and from the entity XML property during .Load() and .Save() operations. It's sweet to be able to have a string key dictionary and then be able to turn around with 1 line of code to persist the whole thing to XML and back. Hopefully some of you will find this class as useful as I've found it. It's a simple solution to a common requirement in my applications and I've used the hell out of it in the  short time since I created it. Resources You can find the complete code for the two classes plus the helpers in the Subversion repository for Westwind.Utilities. You can grab the source files from there or download the whole project. You can also grab the full Westwind.Utilities assembly from NuGet and add it to your project if that's easier for you.

• printable PHP manual - 'all but the Function Reference section'

  - by JW01

  My Motivation I find it easier to learn things by reading 'offline'. I'd like to lean back and read the narrative part of a paper version of the official php manual. My Scuppered Plan My plan was to download the manual, print all but the Function Reference section and then read it. I have downloaded the "Single HTML file" version of the manual from the php.net download page. (That version did not contain any images, so I patched-in the ones from the Many HTML files version with no problem.) My plan was to open that "Single HTML file" in an HTML editor, delete the Function Reference section then print it out. Unfortunately, although I have tried three different editors, I have not been able to successfully load-up that massive html file to be able to edit it. Its about (~40MB). I started to look into the phpdoc framework with a view to rendering my own html docs from the source...but that's a steep learning curve for a newby..and is a last resort. I would use a file splitter, but they tend to split files crudely with no regard for html/xml/xhtml sematics. So the question is... Does anyone know know where you can download the php manual in a version that is a kind of half-way house between the 'Single HTML file' and the 'Many HTML files'? Ideally with the docs split into 3 parts: File 1 - stuff before the function reference File 2 - function reference File 3 - stuff after the function reference Or Can you suggest any editors/tools will enable me to split up this file myself?

  - by Jayanth N

  I have some data in the database. I want those data in database to be stored as an xml file. I'm using postgresql 9.1 for database, for xml processing I'm using libxml (http://xmlsoft.org/). I'm writing the code in C language. Please help me. Detailed explanation: I have a client, which sends me a xml file. Server receives the xml file, parses the xml file and stores it in the db. From db i want to send the details in the form of an xml to the client. client: <employee> <name>glen</name> <telephone>123456789</telephone> </employee> <employee> <name>gwen</name> <telephone>123456789</telephone> </employee> server parses this xml file as displayed below: name : glen telephone:123456789 name : gwen telephone: 123456789 and saves it in a database(postgresql9.1) if the client requests for details of the employees, i've to send it in xml form from database.I don't know how to do it can u help me out.

• Is there any way to get Visual Studio 2008 to update .net style comments automatically?

  - by Jon Cage

  I've been writing a lot of VC++ 2008 / CLI software recently and am using the C#/CLI style documentation: /// <summary> /// Function the does stuff /// </summary> /// <param name="someParam">Specifies some option</param> /// <returns>true if it worked</returns> bool DoStuff( bool someParam ); I find myself re-typing those blocks quite frequently and frankly, it's getting repetitive. Is there any way to get Visual Studio to create / update those blocks automatically as you create new function definitions or update existing definitions?

• Loading XML from Web Service

  - by Lukasz

  I am connecting to a web service to get some data back out as xml. The connection works fine and it returns the xml data from the service. var remoteURL = EveApiUrl; var postData = string.Format("userID={0}&apikey={1}&characterID={2}", UserId, ApiKey, CharacterId); var request = (HttpWebRequest)WebRequest.Create(remoteURL); request.Method = "POST"; request.ContentLength = postData.Length; request.ContentType = "application/x-www-form-urlencoded"; // Setup a stream to write the HTTP "POST" data var WebEncoding = new ASCIIEncoding(); var byte1 = WebEncoding.GetBytes(postData); var newStream = request.GetRequestStream(); newStream.Write(byte1, 0, byte1.Length); newStream.Close(); var response = (HttpWebResponse)request.GetResponse(); var receiveStream = response.GetResponseStream(); var readStream = new StreamReader(receiveStream, Encoding.UTF8); var webdata = readStream.ReadToEnd(); Console.WriteLine(webdata); This prints out the xml that comes from the service. I can also save the xml as an xml file like so; TextWriter writer = new StreamWriter(@"C:\Projects\TrainingSkills.xml"); writer.WriteLine(webdata); writer.Close(); Now I can load the file as an XDocument to perform queries on it like this; var data = XDocument.Load(@"C:\Projects\TrainingSkills.xml"); What my problem is that I don't want to save the file and then load it back again. When I try to load directly from the stream I get an exception, Illegal characters in path. I don't know what is going on, if I can load the same xml as a text file why can't I load it as a stream. The xml is like this; <?xml version='1.0' encoding='UTF-8'?> <eveapi version="2"> <currentTime>2010-04-28 17:58:27</currentTime> <result> <currentTQTime offset="1">2010-04-28 17:58:28</currentTQTime> <trainingEndTime>2010-04-29 02:48:59</trainingEndTime> <trainingStartTime>2010-04-28 00:56:42</trainingStartTime> <trainingTypeID>3386</trainingTypeID> <trainingStartSP>8000</trainingStartSP> <trainingDestinationSP>45255</trainingDestinationSP> <trainingToLevel>4</trainingToLevel> <skillInTraining>1</skillInTraining> </result> <cachedUntil>2010-04-28 18:58:27</cachedUntil> </eveapi> Thanks for your help!

• synchronizing XML nodes between class and file using C#

  - by Sarah Vessels

  I'm trying to write an IXmlSerializable class that stays synced with an XML file. The XML file has the following format: <?xml version="1.0" encoding="utf-8" ?> <configuration> <logging> <logLevel>Error</logLevel> </logging> ...potentially other sections... </configuration> I have a DllConfig class for the whole XML file and a LoggingSection class for representing <logging> and its contents, i.e., <logLevel>. DllConfig has this property: [XmlElement(ElementName = LOGGING_TAG_NAME, DataType = "LoggingSection")] public LoggingSection Logging { get; protected set; } What I want is for the backing XML file to be updated (i.e., rewritten) when a property is set. I already have DllConfig do this when Logging is set. However, how should I go about doing this when Logging.LogLevel is set? Here's an example of what I mean: var config = new DllConfig("path_to_backing_file.xml"); config.Logging.LogLevel = LogLevel.Information; // not using Logging setter, but a // setter on LoggingSection, so how // does path_to_backing_file.xml // have its contents updated? My current solution is to have a SyncedLoggingSection class that inherits from LoggingSection and also takes a DllConfig instance in the constructor. It declares a new LogLevel that, when set, updates the LogLevel in the base class and also uses the given DllConfig to write the entire DllConfig out to the backing XML file. Is this a good technique? I don't think I can just serialize SyncedLoggingSection by itself to the backing XML file, because not all of the contents will be written, just the <logging> node. Then I'd end up with an XML file containing only the <logging> section with its updated <logLevel>, instead of the entire config file with <logLevel> updated. Hence, I need to pass an instance of DllConfig to SyncedLoggingSection. It seems almost like I want an event handler, one in DllConfig that would notice when particular properties (i.e., LogLevel) in its properties (i.e., Logging) were set. Is such a thing possible?

• Ruby on Rails: Using XML Builder Partials

  - by randombits

  Partials in XML builder are proving to be non-trivial. After some initial Google searching, I found the following to work, although it's not 100% xml.foo do xml.id(foo.id) xml.created_at(foo.created_at) xml.last_updated(foo.updated_at) foo.bars.each do |bar| xml << render(:partial => 'bar/_bar', :locals => { :bar => bar }) end end this will do the trick, except the XML output is not properly indented. the output looks something similar to: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> The <bar> element should align underneath the <last_updated> element, it is a child of <foo> like this: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> Works great if I copy the content from bar/_bar.xml.builder into the template, but then things just aren't DRY.

• How can I stop rails validating xml?

  - by Andrei T. Ursan

  I'm submitting to a rails webservice the following message: xmlPostData = "<message> <message-text>" + MESSAGE_WITH_XML + "</message-text> <name>" + subject + "</name> <f1>" + toPhone + "</f1> <f2>" + fromPhone + "</f2> </message>"; The problem is the the field with contain a text with XML data, is a workaround but I need to be able to submit that xml to the db and get it from there. Can I stop rails validating and replacing my xml in json format? this is how it looks: --- !map:HashWithIndifferentAccess smil: !map:HashWithIndifferentAccess head: !map:HashWithIndifferentAccess layout: !map:HashWithIndifferentAccess root_layout: !map:HashWithIndifferentAccess height: &quot;600&quot; background_color: white width: &quot;800&quot; type: text/smil-basic-layout body: !map:HashWithIndifferentAccess par: !map:HashWithIndifferentAccess text: !map:HashWithIndifferentAccess left: &quot;33&quot; begin: &quot;33&quot; dur: &quot;33&quot; val: 34343434343434343aaaaaaa height: &quot;33&quot; width: &quot;33&quot; top: &quot;33&quot; And this is the ruby method from the rails webservice: # POST /messages # POST /messages.xml def create @message = Message.new(params[:message]) respond_to do |format| if @message.save flash[:notice] = 'Message was successfully created.' format.html { redirect_to(@message) } format.xml { render :xml => @message, :status => :created, :location => @message } else format.html { render :action => "new" } format.xml { render :xml => @message.errors, :status => :unprocessable_entity } end end end Is a workaround but for the moment this has to work ...

• Perl - Read XML

  - by chinna_82

  XML <?xml version='1.0'?> <employee> <name>Smith</name> <age>43</age> <sex>M</sex> <department role='manager'>Operations</department> </employee> Perl use XML::Simple; use Data::Dumper; $xml = new XML::Simple; foreach my $data1 ($data = $xml->XMLin("test.xml")) { print Dumper($data1); } Above code managed to all the xml value like this. Output $VAR1 = { 'department' => { 'content' => 'Operations', 'role' => 'manager' }, 'name' => 'John Doe', 'sex' => 'M', 'age' => '43' }; How do I do, if I only want to get the role value. For this example I need to get Role = manager. Any advice or reference link is highly appreciated.
