Iterating through all nodes in XML

Question

I am very new to C#. I've got XML file. I would like to iterate through all nodes and show values node by node. And at the end, i want to store this value in strings. For example, i want something like this:

First iterate:

string name: Belgian Waffles
string price: $5.95
string description:Two of our famous Belgian Waffles with plenty of real maple syrup
string calories: 650

Second iterate:

string name: Strawberry Belgian Waffles
string price: $7.95
string description:Light Belgian waffles covered with strawberries and whipped cream
string calories: 900

and etc

 <?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
<food>
    <name>Belgian Waffles</name>
    <price>$5.95</price>
    <description>

Maybe you could start with reading on how this is done. For example : https://stackoverflow.com/questions/642293/how-do-i-read-and-parse-an-xml-file-in-c. And then come back if have specific issues. — Sebastien, May 15 '20 at 13:01
I'd suggest you **deserialize** the XML into a C# class first. And it's generally bad practice to model numeric values as strings when appropriate numeric types are available. — Jason, May 15 '20 at 13:36

Here's a console app that does what you want. You'll need to include System.XML.Linq

using System;
using System.Xml.Linq;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {

            var doc = XDocument.Load("C:\\Temp\\menu.xml");

            foreach (XElement xe in doc.Descendants("food"))
            {
                Console.WriteLine("Name:" + xe.Element("name").Value);
                Console.WriteLine("Price:" + xe.Element("price").Value);
                Console.WriteLine("Description:" + xe.Element("description").Value);
                Console.WriteLine("Calories:" + xe.Element("calories").Value);
            }

            Console.Read();
        }
    }
}
