XElement.SetElementValue(XName, Object) Method (System.Xml ..

Scenario. I've got a very simple scenario.I have data in an XML document and its big. I know the document has books (an inventory of books) with important details about each book. I would like to use LINQ and its condition features, such as, the where clause, to filter XML elements based on a search value.. For example, I would enter the name of the book and I get the details about the. XElement root = new XElement (Record); The string Record is automatically converted to an XName object and this is used to set the Name property of the new XElement. An XName is used instead of a simple string because XML names have some additional behaviour because of namespaces - more later

The code checks if the set value is of type DynamicXElement (this means that we want to add a container element) as a child the default constructor gets called here). In that case, we just create a blank container element. If not, we just add a child with the specified name and value Question. How to set an empty element with an attribute xsl:nil=true using XSLT To update a XML element using LINQ to XML, first an element attribute or sub-child is queried out from all of the elements using LINQ then a 'SetValue' method of 'XElement' or 'XAttribute' is called to set a new value. Following example demonstrates this concept Product Value: This simply is how much bang for the buck you get from your Xelement Motorcycle Boots.

C# Declaring a 2D array without knowing its size from XML

Hi all I'm trying to learn how to read and iterate though XML data using .element and .attribute and then for each loops e.g trying things like 'XMLData(my variable).Element(data).Element(columns).Attribute(Age).ToString' but I've noticed the XML data is set up slightly differently to what I've seen in that it has columns information then records (as opposed to. public XElement Element { set { this.MyVar1 = value.Element( MyVar1).Value; // this element is missing - exception!!! this.MyVar2 = value.Element( MyVar2).Value; } }. I discovered that when a database column contains NULL as its value, and the stored procedure will not return the desired/expected XML child element for the row, the code shown above will throw an exception

XElement.SetValue, System.Xml.Linq C# (CSharp) Code ..

We are excited to announce that the ASP.NET Forums are moving to the new Microsoft Q&A experience A C# helper class to read and write XML from and to objects - XmlHelper.c The reason is that once the XDocument is loaded, every element in the tree gets prefixed with the namespace name. So we need to change them all, and so I wrote the following method that does this: static void Main ( string [] args) {. // Load the xml document. XDocument source = XDocument.Load ( @instance.xml ) /// Set a save value in the root node so that the containing xml file class /// knows that the file has changed, and therefore saves the changes. /// Instead of saving the file everytime even when no changes were made

c# - How to add value between tags using XElement? - Stack

In every tag we used the same XElement with two arguments. The first is a Name of the tag and the next is its corresponding value. After doing this, add the element to its upper hierarchy element (or parent element). At last, we used the WriteLine() method to display the whole format of the XML file will set an existing XElement child of root with XName Tel to a value of 123 or if such a XElement doesn't exist it will first create a new instance. There is some apparently odd behaviour here in that the value 123 is applied between a new pair of tags <Tel>123</Tel> but it is also appended to root's Value property as if.

home > topics > visual basic .net > questions > xelement, xattribute default values Post your question to a community of 468,629 developers. It's quick & easy The previous pattern involved in creating XML is to create a node, set a value, and append the child. This involves multiple lines of code. LINQ to XML introduces a number of helper objects in the System.Xml.Linq namespace designed to allow developers to build and manage XML contents through parameter arrays and other functions that allow for.

I got it to work with a few minor changes. For some reason it was throwing a null ref exception when I set the DataSource directly to the IEnumerable<XElement> property so I created a new 'root' XElement and set the DataContext to it and bound the grid to its Elements () like this: <Grid DataContext= {Binding Jobs}> There are two ways to do so: Using the XElement class or the XDocument class. Both the classes contain the 'Load()' method which accepts a file, a URL or XMLReader and allows XML to be loaded In the LoadProducts procedure, you will use the Load method of the XElement class to load the XML file. Once the XML file has been loaded, you write a LINQ query to iterate over the Product descendants in the XML file. This will automatically add a key called Name and set the value Bruce into that location. Using the key/value. An XElement/XDocument is not strongly typed, it is a representation of a Xml document; One must write code to pull information from the XElement/XDocument. This is straight forward with Linq to Xml, but complexities can arise. One must convert the string values to appropriate data types as needed

GetDescendants(name, true) : XElement.EmptySequence; 3770/// Returns the default <see cref=XNamespace/> of an <see cref=XElement/> 3778/// Get the namespace associated with a particular prefix for this <see cref=XElement/> 3802XElement e = this; 3823e = e.parent as XElement; 3837/// <see cref=XElement/> and initializing it from a data. Yes, why not. But I strongly suggest giving better names - ElementExists does not indicate that you get the Descendents, e.g. DescendentsOrEmpty instead of ElementExists. You are also a bit over-using parenthesis. Finally, the lib is never null in this context, so, you can directly access lib.Value - the Value may be null, so you might want to return lib.Value ?? string.Empty to always have a. And I know how to convert an XElement into an. I understand generics, anonymous functions, delegates, all the more complicated language features of C#, but I cannot, for the life of me, figure out XML in C# (or why it has to be so difficult) XML is not as popular as it once was, but there's still a lot of XML based configuration and data floating around today. Today I ran into a recurring issue where I needed to convert a string to a properly encoded XML string. Seems simple enough but it's not as straightforward as you might think to generate an XML Encoded string properly. This post shows a few different ways to retrieve a. Dim productIDIncrementCounter As Integer = Me.GetMaxProductID () productElement.SetElementValue (ProductID, productIDIncrementCounter + 1) 'Add the XElement to the Products node. productsElement.Add (productElement) Return productElement End Function 'helper method to get the max CategoryID in the XML file Private Function GetMaxCategoryID.

  2. So above we have a small XML file catag my two cats. Within the Info tags you may notice that the first Cat entry has a superfluous character, 0x13; this falls outside of the valid XML character set [1]. The W3C recommendation, however, is no guarantee that every XML file that you encounter will follow the recommendations to a tee
  3. LINQ or Language Integrated Query, as you know is set of features introduced first with .Net framework 3.5 (Visual Studio 2008), which provides powerful queries (language) to read and update literally any kind of data storage.LINQ provides necessary classes, methods and properties to read and update XML documents too. Here in this article, I am going to show you, with small examples, on how to.
  4. for this XDocument I want to add one child XElement() under . I want to write a generic method for this. I can do the above like this. XDocument xdoc=new XDocument() XElement xelem=new XElement(Leaf1, new XAttribute(name,ADO.NET))

  6. As you can see, the item element has been automatically pluralized to items and the array contains two record values that consist of the value attribute. The conversion function is a recursive function that takes a XElement and produces JsonValue. It builds JSON records (using JsonValue.Record) and arrays (using JsonValue.Array)
  7. g model to read, construct and write XML data. We can use LINQ to XML to perform LINQ queries over XML. It provides much richer querying support than the low-level XmlReader/XmlWriter API in .NET. It uses less memory and more efficient than the XmlDocument.

  3. VB.NET LINQ Examples - Dot Net Perls. VB.NET LINQ Examples Use LINQ, a set of extensions to the language that enables query expressions. dot net perls. LINQ. This stands for Language Integrated Query. In VB.NET we import the System.Linq namespace—this provides many extension methods, ones that act on collections. LINQ allows queries
  4. LINQ to XML allows querying XML data. A new namespace in .NET 3.5, System.Xml.Linq, contains classes for creating and querying XML trees, in the XPath style: XName, used for namespace qualified identifies (Qname), used both as element and attribute name; XName objects are atomized, which means that if two XName objects have the same namespace.
  5. gElement object
  6. Mean is the statistical average of a set of numbers. This one is easy with LINQ because of the Average function. In C#: int[] numbers = { 4, 4, 4, 4, 3, 2, 2, 2, 1 }; The C# code uses the XElement methods and the VB code uses XML literals. You could use object initializer syntax in this example to initialize all of the objects to some.
  7. To work with LINQ and XML, we will add one XML file in our application. For that, we will right-click on the application-> Select Add-> Select New Item, as shown below: After clicking on the new item, a new popup will open in that select XML file from the Data Section → Give a name to the XML File->Click Add button, as shown below

c# - Get XML elements with a particular attribute value

LINQ to XML is a programming interface that lets the developers use LINQ (Language Integrated Query) to manage XML data. It simplifies a lot of XML data manipulation procedures, for example. Deserialize old version of xml¶. In standard XMLSerializer you can't deserialize XML in case you change model. In ExtendedXMLSerializer you can create migrator for each class separately. E.g.: If you have big class, that uses small class and this small class will be changed you can create migrator only for this small class I have to remove all child nodes from every row node except for the WarehouseCode node. I tried this method but obviously I'm wrong and nothing changes: XDocument xdoc = XmlHelper.LoadXDocFromString (xmlOITM) The value of an element is the item displayed on the right side of the start-tag. It is also called the text of the element. In the case of <Director>Jonathan Lynn</Director>, the Jonathan Lynn string is the value of the Director element. To support the text or value of an element, the XmlElement class is equipped with the Value property will set an existing XElement child of root with XName Tel to a value of 123 or if such a XElement doesn't exist it will first create a new instance. There is some apparently odd behaviour here in that the value 123 is applied between a new pair of tags <Tel>123</Tel> but it is also appended to root's Value property as.

To implement a selection in the MVVM style, enable the selection feature using the ChartControl.SelectionMode property. Set this property to a value different from None. Then, use the ChartControl.SelectedItem property to set or get a single selected view model object, or the ChartControl.SelectedItems property to set or get. Attributes - two overloads; the first accepts no input parameters and returns all attributes of the XElement; the second overload accepts an attribute name and returns a collection of attributes of the XElement with a matching name. And like XElement, The XAttribute class has a Value property, which returns the value of the attribute Binding data from XML. To bind XML data to a TabNavigation control, convert the XML data to a collection like Observable collection or ILIST collection, and then bind the collection by using the ItemsSource property of the TabNavigation control

LINQ to XML does introduce a new class hierarchy in .NET 3.5. The essential class in this hierarchy is the XElement class in the System.Xml.Linq namespace. One technique you can utilize with XElement is the functional construction of XML as shown in the following code sample Notice above how I'm using the explicit conversion operator support on the XElement class to retrieve strongly typed values from the XML. This enables me to just cast the c.Element(YearsAtCompany) value to an int - and it will then automatically convert the string value to an integer for me, and type the YearsAtCompany property on my.

Essentially, static ctors are commonly best used to set static members of the class (whether the class itself is static or not). With a static class, the only operations that execute when the class is created is the assignment of static field values, and the static ctor. = entry.Key.ToString() let value = (entry.Value == null) ? null.

  3. C# List (List<T>) In c#, List is a generic type of collection, so it will allow storing only strongly typed objects, i.e., elements of the same data type. The size of the list will vary dynamically based on our application requirements, like adding or removing elements from the list. In c#, the list is same as an ArrayList, but the only.
  4. Using LINQ to SQL is simple but introduces code that is tightly-coupled with this kind of data access method. One way to solve this is to use the repository pattern.
