[C# Console App] Output All Node Names in a XML file.

[abhijit]

This came up as a requirement in one of our projects. The objective of this is to put all node names in an excel file. The example I have uses a recursive function to output all node names.

using System;
using System.Xml;
 
namespace StripMe
{
    class Class1
    {
        public static int GetNodeTypeCount(XmlNode node, XmlNodeType nodeType)
        {
            // Recursively loop through the given node and return 
            // the number of occurences of a specific nodeType.
            int i = 0;
 
            if (node.NodeType == nodeType)
                i = i + 1;
 
            if (node.HasChildNodes)
                foreach (XmlNode cNode in node.ChildNodes)
                {
                    i = i + GetNodeTypeCount(cNode, nodeType);
                    if (cNode.NodeType == XmlNodeType.Element)
                        Console.WriteLine(cNode.Name);
                }   
            return i;
        }
 
        [STAThread]
        static void Main(string[] args)
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(args[0]);
                XmlNodeList nodeList = doc.GetElementsByTagName("*");
                Class1.GetNodeTypeCount(doc.DocumentElement, XmlNodeType.Element);
                Console.ReadLine();
            }
            catch (XmlException xmlEx)        // Handle the XML Exceptions here.         
            {
                Console.WriteLine("{0}", xmlEx.Message);
            }
            catch (Exception ex)              // Handle the Generic Exceptions here.
            {
                Console.WriteLine("{0}", ex.Message);
            }
        }
    }
}

The way to use this is pass the file name that you want to parse as the first parameter.
For e.g -
c:\>TraverseXML Quote.XML
