[c#] XML Reader / Writer

[jayfella]

Here's a handly little class that i use very often to read/write XML files. Its a very handy little tool to save settings or anything else you wish to read/write often.

Hope you find it useful

Useage:

setting mySettings = new settings("myFile.xml");

//  To Retrieve Values
string myString = mySettings.getSettings("myNodeName");

// To Set Values
mySetting.setSettings("myNodeName", "myValue");

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.IO;

namespace Jayfella.XMLParser
{
    class Settings
    {
        private string xmlFile;
        private XmlDocument xmldoc = new XmlDocument();
        
        public Settings(string xmlFile)
        {
            this.xmlFile = xmlFile;
            initXml();
        }

        private bool initXml()
        {
            try
            {
                xmldoc.Load(xmlFile);
            }
            catch (Exception)
            {
                TextWriter writer = new StreamWriter(xmlFile);
                writer.WriteLine("<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>");
                writer.WriteLine("<Settings>");
                writer.WriteLine("</Settings>");
                writer.Close();
            }
            return true;
        }

        public string getSetting(string settingNode)
        {
            xmldoc.Load(xmlFile);
            XmlNodeList list = xmldoc.GetElementsByTagName("Settings");
            try
            {
                foreach (XmlNode searchNode in list)
                {
                    return searchNode.SelectSingleNode(settingNode.Replace(" ", "_")).InnerText;
                }
            }
            catch (Exception)
            { }
            return "";
        }
        
        public bool setSetting(string settingNode, string newValue)
        {
            xmldoc.Load(xmlFile);
            XmlNodeList list = xmldoc.SelectNodes("Settings");
            try
            {
                foreach (XmlNode searchNode in list)
                {
                    XmlNode node = searchNode.SelectSingleNode(settingNode.Replace(" ", "_"));
                    if (node == null)
                    {
                        XmlElement element = xmldoc.CreateElement(settingNode.Replace(" ", "_"));
                        xmldoc.DocumentElement.AppendChild(element);
                        searchNode.SelectSingleNode(settingNode.Replace(" ", "_")).InnerText = newValue;
                    }
                    else
                        searchNode.SelectSingleNode(settingNode.Replace(" ", "_")).InnerText = newValue;
                }
            }
            catch (Exception)
            { return false; }
            xmldoc.Save(xmlFile);
            return true;
