Please specify reason you are doing it (education, assignment, code to be used). Depending on the reson answers will be different. Note that HTMLAgility pack is traditional answer to this question... — Alexei Levenkov, Apr 19 '13 at 05:25
Than most likely you want to use existing library - it does not look like you are interested in learning all intricacies of parsing markup yourself. — Alexei Levenkov, Apr 19 '13 at 05:36
If you are wanting to parse the HTML, your best bet will be to use a library, like [the HTML Agility Pack](http://htmlagilitypack.codeplex.com/) — Kevin Anderson, Apr 19 '13 at 05:25
For one scenario on a single page, should I use this library or my custom function? — khawarPK, Apr 19 '13 at 05:29

You can use XML schema related classes for the same.

using System;
using System.IO;
using System.Xml;

public class Sample
{

    public static void Main()
    {

        XmlDocument doc = new XmlDocument();
        doc.LoadXml("<input title='Meluha' Value='1-861001-75-7'>" +
                    "<title>The Imortals of Meluha</title>" +
                    "</input>");

        XmlNode root = doc.DocumentElement;

        XmlNode value = doc.SelectNodes("//input/@value")[0];

        Console.WriteLine("Inner text: " + value.InnerText);

    XmlNode value = doc.SelectNodes("//title/@value")[0];

    Console.WriteLine("Title text: " + value.InnerText);
     } 
}

But HTML is not quite XML. Will it work for self closing html tags? — nam, Apr 07 '21 at 22:15
