   Hi,   
      
   I want to build a tool for data mining from an html page. I want the user to   
   select an element from a web page, and train my application to recognize it   
   in its later updates. For example, suppose the user wants to extract some   
   data from a financial. He want to extract his total balance, plus the table   
   of the last transactions. What he should do is to highlight the elements   
   inside the html page. After doing that, the application should analyze the   
   html element structure, and learns how to find it in similar pages (even   
   when they are not identical). What I really need is an algorithm to   
   "understand" a single element (by it's structure, position in page or any   
   other methods), and then I want to look in a new page, and choose the most   
   similar element (which should probably be the right one).   
      
   Does anyone has an idea for it?   
      
   Regards,
