It seems to me from your curt description that you want to download a HTML page and look for text in it. If you want to emulate a browser, WWW::Mechanize could be a fit for your problem. Also, possibly Web::Scraper might be a solution. It's unclear to me whether you have searched CPAN or whether you actually know enough about HTTP and HTML to attack the problem with Perl.

...or, given the majority of previous postings from the OP, whether there's even sufficient familiarity with perl or ... to put it another way, one wonders if the OP is attempting to run before being able to walk ?
A user level that continues to overstate my experience :-))

I believe anbutechie is a social experiment. Three people actually post questions, only one is a programmer, but all three are completely uninterested in the questions they ask. Their goal is to get solutions to the questions with the least effort/interest and zero follow through. People always attempt to help, but it never leads to a resolution. Maybe its a hope experiment?

'in view source( "Application messages which is defined in server side script can be called from web span")'

I have no idea what you mean by that. This looks like an update to a previous post of yours. As Corion has pointed out WWW::Mechanize is a good starting point, for processing/stripping the HTML you may want to look at HTML::TokeParser::Simple.
