Free SEO Tools And VB.NET, XML and RegEx Code Snippets

I have been coding and designing websites for quite sometime. I like what I do very much, but there are a few things I wish I did not have to deal with. Like getting stuck with a minor coding problem and having to spend hours trying to find a solution. There is nothing more frustrating in my line of work than wasting precious time only to find out that the solution was as easy as 1-2-3. I would like to thank all those generous souls who posted on countless webmaster forums and helped me out. Thank you so very much. Below is a list of code snippets and SEO tools that I find most useful and that I would like to share with you. Feel free to suggest improvements or report bugs. All tools have been tested using Google Chrome browser only.
