Reading HTML Page(Source Code) Control Properties.

Hii Experts.
My requirement is like
1. The requirement is, I have to read all/some of the Control's Name, Type, Properties and Data Entered in Controls of a given page (Dynamic page)
2. Save the data in excel sheet in corresponding fields.
What i did is 
 I had developed one Web Page in VS with one URl Text Box.
 
Just enter any one working url in that TextBox.
 
By Clicking ?Get Script? Button. The url?s Webpage Source code injected in to our developed Webpage.
txtPageHTML.Text = oUTF8.GetString(PageHTMLBytes);
ClientScript.RegisterOnSubmitStatement(
this.GetType(), "ConfirmSubmit", oUTF8.GetString(PageHTMLBytes));
 
Now I am looping through all the control ...
