(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.
Here’s an example: Couple things to note above, remember to import any namespaces being used in the XML otherwise your query will yield no results.
Value == "Java") select item; foreach (var item in items) xml Doc. Save("d:/data.xml"); 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. NET, HTML, CSS, JQuery, Java Script and other applications such as MS Excel, MS Access, and MS Word.
Equals("Java") select ele; foreach (var e in elements To Delete) xml Doc.
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"?
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?
I want to update an existing XDocument File that looks like this: What is the easiest way to change a value in a specific Element?
Of course, you can load the XML from a file (or URI) instead of using a literal and and get the same results.
The main reason for doing this is that most of the collections you retrieve from an XML tree are yielded using deferred execution.
If you do not first materialize them into a list, or if you do not use the extension methods, it is possible to encounter a certain class of bugs.
However, when removing collections of elements or attributes, you should first materialize a collection into a list, and then delete the elements or attributes from the list.
The best approach is to use the Remove extension method, which will do this for you.
