Parse domains from HTML page

I need a small program that will extract a list of sub domains from an HTML page. Each sub domain would be in the format *.*.* Each * would be alphanumeric. Each * must contain at least one alphabet. When extracting sub domains, it would eliminate repeats Once all the subdomains are extracted, it must ping or retrieve the IP of that sub domain and display it in the list, next to each sub domain.
