What is the LINQ To XML positioning method?

This article introduces the relevant knowledge of "what is the positioning method of LINQ To XML". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

LINQ To XML positioning method

The 1.LINQ To XML positioning method-- Ancestors: returns all the parent elements of the specified node. (AncestorsAndSelf: returns all the parent elements that include yourself)

XElement Students = new XElement ("Students", new XElement ("Student" new XElement ("Name", "Zhang San"), new XElement ("Sex", "male"), new XElement ("Age", new XAttribute ("Year", "1989-8-22"), 20); foreach (var el in Students.Element ("Student"). Element ("Sex"). Ancestors () {Console.WriteLine (el);}

The 2.LINQ To XML location method-- Descendants: returns a collection of all subsequent identical elements for all specified element names.

XElement Students = new XElement ("Students", new XElement ("Student", new XElement ("Name", "Zhang San"), new XElement ("Sex", "male"), new XElement ("Age", new XAttribute ("Year", "1989-8-22"), 20), new XElement ("Student", new XElement ("Name", "Li Si"), new XElement ("Sex", "female"), new XElement ("Age", new XAttribute ("Year") "1990-8-22"), 20)) Foreach (var v in Students.Descendants ()) {Console.WriteLine (v); Console.WriteLine ("- -");}

3.LINQ To XML positioning method-ElementsAfterSelf: returns all nodes after the current node. (ElementsBeforeSelft: returns all nodes before the current node)

XElement Students = new XElement ("Students", new XElement ("Student", new XElement ("Name", "Zhang San"), new XElement ("Sex", "male"), new XElement ("Age", new XAttribute ("Year", "1989-8-22"), 20), new XElement ("Student", new XElement ("Name", "Li Si"), new XElement ("Sex", "female"), new XElement ("Age", new XAttribute ("Year") "1990-8-22"), 20)) This is the end of foreach (var v in Students.Element ("Student"). ElementsAfterSelf () {Console.WriteLine (v); Console.WriteLine ("- -");} "what is the LINQ To XML positioning method". Thank you for reading.
