Updating xml using c
For example using Xml Document (the DOM implementation from Microsoft) this would be a typical way to create an XML tree. Inner Text = "206-555-0144"; Xml Element phone2 = doc. XDocument contacts Doc = new XDocument( new XDeclaration("1.0", "utf-8", "yes"), new XComment("LINQ to XML Contacts XML Example"), new XProcessing Instruction("My App", "1"), new XElement("contacts", new XElement("contact", new XElement("name", "Patrick Hines"), new XElement("phone", "206-555-0144"), new XElement("address", new XElement("street1", "123 Main St"), new XElement("city", "Mercer Island"), new XElement("state", "WA"), new XElement("postal", "68042") ) ) ) ); XML names LINQ to XML goes out of its way to make XML names as straightforward as possible.Xml Document doc = new Xml Document(); Xml Element name = doc. Inner Text = "Patrick Hines"; Xml Element phone1 = doc. Arguably, the complexity of XML names, which is often considered an advanced topic in XML literature, comes not from namespaces, which developers use regularly in programming, but from XML prefixes.A few examples include the following: You should be able to accomplish most XML programming tasks you run into using this technology. XML nodes are created in the context of the XML document.LINQ to XML is designed to be a lightweight XML programming API. If you want to use an element across multiple documents you must import the nodes across documents.LINQ to XML is a language-agnostic component of the LINQ Project. Functional construction is described further in the section titled "Creating XML From Scratch." Document "free" When programming XML your primary focus is usually on XML elements and perhaps attributes.The samples in most of this document are shown in C# for brevity. This makes sense because an XML tree, other than at the leaf level, is composed of XML elements and your primary goal when working with XML is traversing or manipulating the XML elements that make up the XML tree.XML prefixes can be useful for reducing the keystrokes required when inputting XML or making XML easier to read, however prefixes are just a shortcut for using the full XML Namespace.On input LINQ to XML resolves all prefixes to their corresponding XML Namespace and prefixes are not exposed in the programming API.
The next section of this document, "Programming XML", provides more detail on the in-memory XML Programming API aspect of LINQ to XML. XElement contacts = new XElement("contacts", new XElement("contact", new XElement("name", "Patrick Hines"), new XElement("phone", "206-555-0144", new XAttribute("type", "home")), new XElement("phone", "425-555-0145", new XAttribute("type", "work")), new XElement("address", new XElement("street1", "123 Main St"), new XElement("city", "Mercer Island"), new XElement("state", "WA"), new XElement("postal", "68042") ) ) ); Notice that by indenting (and squinting a bit) the code to construct the XML tree shows the structure of the underlying XML.Michael Champion February 2007 Applies to: Visual Studio Code Name "Orcas" .Net Framework 3.5 Summary: LINQ to XML was developed with Language-Integrated Query over XML in mind and takes advantage of standard query operators and adds query extensions specific to XML.Yet, from a development perspective, XML is still hard to work with.If you ask the average software developer to work in XML you will likely hear a heavy sigh.
