in reply to HTML stripper in WWW::Mechanize doesn't seem to work

I can't find in the documentationon your "content(format=>'text')" call. You probably should use some other parsers, such as HTML::TokeParser: 
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";
}

    I installed WWW::Mechanize (I may even end up using it someday), and looked through the docs: 
    $mech->content(...)

Returns the content that the mech uses internally for the last page
fetched. Ordinarily this is the same as $mech->response()->content(),
but this may differ for HTML documents if "update_html" is overloaded
(in which case the value passed to the base-class implementation of
same will be returned), and/or extra named arguments are passed to con
+-
tent():

$mech->content( format => "text" )
  Returns a text-only version of the page, with all HTML markup
  stripped. This feature requires HTML::TreeBuilder to be installed, o
+r
  a fatal error will be thrown.

    So it looks like the call is correct.

      Right, i have made the neccessary changes and i think the code works fine now. The problem is i don't quite think the content( format => "text" ); function in the WWW::Mechanize http://search.cpan.org/dist/WWW-Mechanize/lib/WWW/Mechanize.pm module works. I have used it with google and perlmonks.com and it gives me the whole content. Does anyone else have the same problem or is it something with my code?

      Updated code: 

      #!/usr/bin/perl 
use strict;

#Module used to go through the web pages, Can extract links, save them
+ and also strip the HTML of its contents
 use WWW::Mechanize;
 use URI;
  
 print "WEB CRAWLER AND HTML EXTRACTOR \n";
 print "Please input the URL of the site to be searched \n";
 print "Please use a full URL (eg. http://www.dcs.shef.ac.uk/) \n";
 
 #Create an instance of the webcrawler
 my $webcrawler = WWW::Mechanize->new();
  
 my $url_name = <STDIN>; # The user inputs the URL to be searched
 
 my $uri = URI->new($url_name); # Process the URL and make it a URI
 
 #Grab the contents of the URL given by the user
 $webcrawler->get($uri);
  
 # Put the links that exist in the HTML of the URL given by the user i
+n an array
 my @website_links = $webcrawler->links($uri);  
 
 # The HTML is stripped off the contents and the text is stored in an 
+array of  strings
 my $x = 0;
 my @stripped_html;
 $stripped_html[$x] = join ' ', $webcrawler->content( format => "text"
+ );
 print $stripped_html[$x];
 $x = $x + 1;
 exit;
