now, im curious, how is html code being read? what program on the system (let's assume its a Unix system) must exist for an html page to be read and processed?
Are you talking about in the context of a file manager? So you go into a folder and you can see by the icons that you have a perl script, or a python script, or an html file; and clicking on the icon will run the script or open the html file in a browser?

html::display::common
HTML::Display::Common(3pm) User Contributed Perl Documentation HTML::Display::Common(3pm)
NAME
HTML::Display::Common - routines common to all HTML::Display subclasses
__PACKAGE__->new %ARGS
Creates a new object as a blessed hash. The passed arguments are stored within the hash. If you need to do other things in your
constructor, remember to call this constructor as well :
package HTML::Display::WhizBang;
use parent 'HTML::Display::Common';
sub new {
my ($class) = shift;
my %args = @_;
my $self = $class->SUPER::new(%args);
# do stuff
$self;
};
$display->display %ARGS
This is the routine used to display the HTML to the user. It takes the following parameters :
html => SCALAR containing the HTML
file => SCALAR containing the filename of the file to be displayed
base => optional base url for the HTML, so that relative links still work
location (synonymous to base)
Basic usage :
my $html = "<html><body><h1>Hello world!</h1></body></html>";
my $browser = HTML::Display->new();
$browser->display( html => $html );
Location parameter :
If you fetch a page from a remote site but still want to display it to the user, the "location" parameter comes in very handy :
my $html = '<html><body><img src="/images/hp0.gif"></body></html>';
my $browser = HTML::Display->new();
# This will display part of the Google logo
$browser->display( html => $html, base => 'http://www.google.com' );
