Updating xml with linq
Serialization/Deserialization is a cool and important feature of an application.It is required when your want to communicate/send data to other applications.Load("Data.xml"); XElement new Tree = new XElement("Root", root. However, if you have many changes to make to an XML tree, the non functional approach will become quite complex and somewhat obtuse.
For this example, suppose you want to modify the following simple XML document so that the attributes become elements.
Here is the XML file created in the previous lesson. Add(new XElement("Book", new XAttribute("title", "AJAX"), new XElement("author", "Khemrin"), new XElement("year", "2000"))); xml Doc. You need to query the elements that meet your criteria. Here is an example code that removes the element that has "Java" title attribute. Load("d:/data.xml"); var elements To Delete = from ele in xml Doc. Delete Xml Data By Expression("~/App_Data/XML/persons.xml", "Persons/Person[Age='27']"); 2017-10-03 This website intents to provide free and high quality tutorials, examples, exercises and solutions, questions and answers of programming and scripting languages: C, C , C#, Java, VB.

By using Linq query expression, you can easily read all elements of the xml file. = null select ele; foreach (var e in elements) The Linq expression to add a new element to the xml file is similary to reading from that file. Save("d:/data.xml"); Simetimes, you might want change or udate a element of xml file. Then assign new values to their attributes or sub-elements. However, we don't guarantee all things of the web are accurate.
In this post LINQ to XML Update Element Values, we shall see how to update the values of elements in an existing XML structure.
We will load an XML file from the disk, update the values of the elements and save the updated XML to the disk.

After designing an entity, we have Deserialization Object() method, which takes XML data parameter and returns object.
