Introduction

This is HTML parser for getting Titles, Texts and Links from the page, it is a dll file using C# but you can transform it in an easy way to any programming language when you know, how to get the HTML code from the page

Basic Idea

The idea behind this code is,you parse through the HTML code character by character then if you get the title tag represent the text after it to the title string, if you go to body tag then accept all text which not language script or CSS, and the same for the links

Brief Code Description

i make lookup table for some special characters like when you read in the HTML code the characters &lt; this represent the < character

public string GetTitle(string Source)
{
        int len=Source.Length;
    string title="      ";
    char c;
    for(int i=0;i<len;i++)
    {
        c=Convert.ToChar(Source.Substring(i,1));
        title=title.Remove(0,1);
        title+=c;
        if(title.ToLower()=="<title")
        {
            while(c!='>')
            {
                i++;
                c=Convert.ToChar(Source.Substring(i,1));
            }
            title="";
            i++;
            c=Convert.ToChar(Source.Substring(i,1));
            while(c!='<')
            {
                title+=c;
                i++;
                c=Convert.ToChar(Source.Substring(i,1));
            }
            break;
        }
    }
    return title.Trim();
