Hi there, i have been testing some code i found in this website and i 've realized it works a bit funny when i change some things on it and i dont understand why. The initial code is this:

use WWW::Mechanize;
use HTML::TokeParser;

my $webcrawler = WWW::Mechanize->new();
$webcrawler->get("http://www.google.com");
my $content = $webcrawler->content;
my $parser = HTML::TokeParser->new(\$content);
while($parser->get_tag){
    print $parser->get_trimmed_text(),"\n";
}

[download]

It gives me the output i want, stripping almost all the HTML from a web page and leaving the contents.Now, if i don't have the webpage specified here and i try to get it with the <STDIN> command when i try to compile and run the program with the perl command then the script gets stuck. It won't even let me type a URL in.

$url_name = <STDIN>; # The user inputs the URL to be searched
 $webcrawler->get($url_name);

The 3rd version is when the while statement starts i want to save the $parser variable instead of printing it. I tried to save it as an element of an array and a variable on its own.So at the it would change to:

while($parser->get_tag){
   my $stripped_html = $parser->get_trimmed_text(),"\n";
    #print $parser->get_trimmed_text(),"\n";
   print $stripped_html;
    }

But this gets stuck again for some reason and looking at the proccesses it takes a lot of my CPU power so it probably gets stuck somewhere although i dont know where.This is the same if i initialize an array and use the first element of that array to write the $parser in. Any ideas?Thanks in advance
