HTML::SimpleLinkExtor

[Nandita Shenvi]

Hallo All,

I tried to solve my problem using HTML::SimpleLinkExtor and HTML::LinkExtor.In both cases I got a similar error message.

my scrpit is as follows:
#!/usr/bin/perl -w



use strict;
use HTML::TreeBuilder; #Parser that builds HTML syntax
tree
use HTTP::Request::Form; #Construct HTTP::Request objects for
Form processing
use HTML::Parse;
use HTTP::Request::Common; #Construct common HTTP::Request objects
use LWP::UserAgent; #Provides an object for clients,
UserAgent object acts as a browser
use LWP::Simple;
use URI::URL;
use HTML::SimpleLinkExtor; #Module to extract Links
use Data::Dumper;
use HTTP::Headers;

# Upload the Website
my $url = url 'http://some_host/navitune.html';
my $ua = new LWP::UserAgent; # Create a LWP::UserAgent
object
$ua->requests_redirectable ( ['POST'] ); # Add METHOD POST for
redirection
my $res = $ua->request(POST $url);


# Parse the website and extract the Form
my $tree = new HTML::TreeBuilder->parse( $res->content);
$tree->eof(); #Signals that
you are finished with parsing content into the tree
my @forms = @{ $tree->extract_links('FORM') };

# The first Form
my $f = HTTP::Request::Form->new( $forms[0][1], $url ); #Constructs a new
form processor
#$f->dump(); # Prints the extrachted Form on the STDOUT

# Fill and Send the Form
$f->field( 'wav_file', 'st11.wav' ); # retrieves or sets a field-value ,
where the fieldname =wav_file ,fieldvalue
= st11.wav, which is also the file to be Uploaded

my $response = HTTP::Response->new;
$response = $ua->request($f->press('submit')); # Practically it clicks the
Submit button and the form is sent.

# Response from the Serverside
$response->as_string(); #as_string is a method of HTTP::Request.It
returns the text version of the request object
as a string with \n placed after each line.

# Parse the website and extrach the first three Links using HTML::LinkExtor
my $linkparser = HTML::SimpleLinkExtor->new(); #Create
SimpleLinkExtor object
$linkparser->parse($response); #Parse response

my @all_links = $linkparser->links; #Gets a list if links

print Dumper \@all_links; #Print list of links out



when i execute this script, I get this: $VAR1 = [ ];

I donot have much experience in perl programming, so i cannot figure out the mistake or am I doing some mistake in my scrpit ?

I would be thankful if somebody could invest time to answer my question.

thanks in advance
