C# reading from a XML file

Question

I'm trying to read a XML in C#, using a button in WPF. I have this XML file:

<?xml version="1.0" encoding="utf-8" ?> <date> <Disciplina nume="Disc1" cadru="Cadru1"> <Student> <Nume>Student1</Nume> <Nota>9</Nota> </Student> </Disciplina> </date>

In the reading Button i have this code:

XmlTextReader rd = new XmlTextReader(@"Test.xml"); string dnume = "", dcadru = "", snume = "",snota="", element = ""; while ( rd.Read() ) { switch (rd.NodeType) { case XmlNodeType.Element: element = rd.Name; break; case XmlNodeType.Text: if (element == "Disciplina") { dnume = rd.GetAttribute("nume"); dcadru = rd.GetAttribute("cadru"); } else if (element == "Student") { } break; case XmlNodeType.EndElement: if (rd.Name == "Student1") { MessageBox.Show(""); } break; } } rd.Close();

The problem is that I don't know how to read the information from the Student node. Can you help me?

Any reason you really need to use XmlTextReader? It's considerably simpler to just load an XDocument... — Jon Skeet

I need to use this because this is what I'm using at the University. Is something for an exam. — Cristian Ch

If you really need to use XmlReader classes you can use a code like below in a Console Application:

var nestedLevel = 0; var studentNestedLevel = 0; using (var reader = XmlTextReader.Create(@"Test.xml")) { while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: nestedLevel++; if (studentNestedLevel > 0) Console.Write("{0}: ", reader.Name); if (reader.Name.ToLower() == "student") studentNestedLevel = nestedLevel; break; case XmlNodeType.Text: if (studentNestedLevel > 0) Console.WriteLine("{0}", reader.Value); break; case XmlNodeType.XmlDeclaration: case XmlNodeType.ProcessingInstruction: if (studentNestedLevel > 0) Console.WriteLine("{0}: {1}", reader.Name, reader.Value); break; case XmlNodeType.Comment: break; case XmlNodeType.EndElement: nestedLevel--; if (reader.Name.ToLower() == "student") studentNestedLevel = 0; break; } } }
