Homebrewed html parsers are rarely as good as homebrewed beer... even after considerable aging.
Suggest you check the available modules with "parse" and/or "html" in their names; read their docs or at least each precis; and then pick one.
Update: just checked. In less than 2 months, you've posted nearly 50 questions. Perhaps you've seen this advice before in reply to one or more of them: study a good introductory text ("Learning Perl" for example); read the tuts here and also look around the Monastery for highly regarded, free tuts available at some (emphasis, "some;" as not all are worth the powder to blow them to hell) on-line college level tuts or courses; and study (hint: google site:perlmonks.org terms terms terms... or Super Search here) nodes that show how others dealt with your problem(s).
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
