Linq xml updating file fort nelson dating girls

, which only contains 2 strings, name and description. Then I populate a new list, which contains many of the same names, but some of them contains descriptions that the other list did not contain.How can I check if the name in the current XML file contains a value other than "no description", which is the default for "nothing"?

Equals("Java") select ele; foreach (var e in elements To Delete) xml Doc.

I'm trying to figure out how I can go about updating my XML file.

Value == item ID select new foreach (var item in items) "; XDocument xml Doc = XDocument. I've seen junior developers get it into their heads that you need a To List or To Array after every single query regardless of usage. Map Path("data.xml")); var items = (from item in xml Doc.

Save("data.xml"); Can we really recommend calls to To List?

Part of the xml file: In the foreach loop how do I check if the person's name is already there, and then check if the description is something other than "no description", and if it is, update it with the new information?

You can use the Nodes-Method on XElement and check manually.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. The example code below gets all ements from the xml file, stores them in elements collection variable and outputs titles of books in the collection. Load("d:/data.xml"); var elements= from ele in xml Doc. However, you will use the Add method to add a new element to the file. The code below will update the author sub-element of a Book element that has "Java" attribute title and its "Dara" author sub-element. Load("d:/data.xml"); var items = from item in xml Doc. I’ve had many questions lately on how you can query for a specific node in an XML document (or fragment) and change it’s value using LINQ.(This must mean that people are really starting to use this stuff so I’m pretty excited.) This is really easy to do because you can modify the values of the selected XElements from your queries and that will change the source XML. Now, you will learn how to read, add, edit, and delete elements of the xml file that is stored in your computer. Then you will use the Remove method of the XElement class to delete that element. If you find any error, please report it then we will take actions to correct it as soon as possible.
